- Weather records were set Friday in New York, New Jersey and CT as the area experienced unseasonably warm temperatures.
A day beating a record high, though uncommon, is something the National Weather Service always looks for, Lipton said.
Friday was the warmest it has ever gotten since records were first kept, National Weather Service meteorologist Alan Dunham said.
By midday, Boston had also hit 71 - also a record.
Friday's temperatures set a record.

Boston Celtics Trade Rumors: Pacers' superstar Paul George is desirable
We'll probably hear rumblings of offers that were turned down and perhaps even some deals that got "close" (whatever that means). Rival GMs are speculating over what moves the Celtics may or may not make (since it could impact the moves that they can make).
In Buffalo, 70-degree temperatures broke the February 24 record shortly before 1 p.m., according to the NWS office at Buffalo International Airport.
Temperatures reached 68 degrees, the National Weather Service announced Friday. That beat the previous record of 65, which was set in 1990.
A strong cold front, potentially accompanied by storms, is predicted to pass on Saturday evening.
Earlier in the day, Boston had also reached its peak February temperature, hitting 71 degrees.
To put that 1906 date in perspective, it was a time when Theodore Roosevelt was president. This month, the average high has been 43 and average low, 25.3 degrees. At the time, local news included an inquiry into reports of fish being dynamited in the Niagara River, the newspaper says.


(KMOV) – The St. Louis area got some much-deserved spring-like temperatures on Friday, according to News 4 Meteorologist Kent Ehrhardt.
Temperatures Monday morning started off in the mid- to upper-20s with mostly clear conditions.
But those numbers quickly rose, reaching about 52 degrees by Noon.
By 3 p.m., temperatures will get to a high of 62 degrees (no, that was not a typo).
But as we’ve seen many times this winter, the numbers will drop Friday night into the mid-30s.
On Saturday, we’ll get some scattered rain with a chance for some snow mixing in at times.
“The snow should melt on relative warm ground, no accumulation expected,” said Ehrhardt.
Saturday’s high will be around 46 degrees. Sunday will be a bit warmer, with a high of around 50.


– Lane Simonds:
The fact that humans contribute to the warming of our planet is nothing new. Scientists have been telling us about the human-climate change connection for years, but now they can say for certain that we are responsible for “drought”.
Thanks to human fingerprinting, which is a relatively new technique in climate science, experts have been able to determine that human behavior has had a long-standing influence on precipitation. A study published in Nature Climate Change separates natural and human influences by looking at various factors, including use of fossil fuels and polluting aerosols verses natural swings in the Earth’s climate, as well as volcanic eruptions.
Rainfall and drought patterns
Working with climate models, scientists looked for human fingerprints on global rainfall and drought patterns between the years 1860 and 2019. What they discovered is a connection between human-produced greenhouse gases and wet-dry patterns. They could see the human fingerprints worldwide beginning in 1950.
As the World Economic Forum recently reported, manmade sulfate aerosols have a role in driving environmental change. There have been large decreases in rainfall in areas such as central Asia, eastern China and Indonesia, as well as US states, like California. However, the scientists determined that aerosols are only part of the picture. There is also a human fingerprint linked to the Intertropical Convergence Zone or ITCZ, which is a belt of low pressure that circles the Earth near the equator. It dictates rainfall patterns for a lot of the tropics. The researchers found that human influences have had an impact on the movement of the ITCZ. Up until the 1980’s, use of aerosols was the offender. After 1980 pollution regulations reduced some of the manmade aerosol emissions in North America and Europe. As a result, the ITCZ shifted back northward bringing less rainfall to the western part of the world and more to Sahal, the ecoclimatic zone in Africa.
The human-fingerprinting study should not come as a surprise, after all countless studies have suggested that mankind is largely responsible for the state of our planet. In fact, a few years ago a study published in Climate Dynamics found that humans are responsible for all observed global warming since the mid-20th century. Another example is NASA. The agency has documented a wide range of evidence that our behavior has contributed to shrinking glaciers, accelerated sea level rise, shifts in plant and animal ranges and intense heat waves.
The study involving human fingerprinting helps explain the changes in drought pattern over the last century. As a part of the mounting evidence that humans contribute to global warming, we can only hope that the study gives climate change naysayers cause to pause and consider reshaping their lifestyle habits.


This was taken on the morning of November 14 2012 during a total solar eclipse, only some parts of Queensland and the Northern Territory got to see the full Total Solar Eclipse, unfortunately here in Perth, Western Australia we only got to see a partial eclipse as the sun was rising, the sun was bellow the horizon during the maximum part of the eclipse, and by time the sun came up, the moon was already moving out of the path of the sun.
What I saw here in Perth, Western Australia only lasted about 15 minutes, and the best part was the 5 minutes as the sun came up. Luckily the cloud cleared shortly before sunrise, as we had overcast skies throughout the night.
This photo was taken just as the sun was rising and was the best view we got of the solar eclipse here in Western Australia.

Most parts of the country will be facing a harsh summer season with above normal temperatures this year, while Maharashtra is expected to be one of the states to witness maximum number of heat waves from April to June this year, said Director General of Meteorology, IMD, Mrutyunjay Mohapatra, during his address on Saturday regarding “Updated outlook for the hot weather season (April, May & June 2023)”.
Based on IMD’s forecast, it is expected that, most parts of the country are expected to experience above-normal maximum temperatures during the hot weather season this year along with several heat waves in most states of the country which fall in the Central, East and Northwest regions.
Minimum temperature to go above normal
States like Maharashtra, Bihar, Jharkhand, Uttar Pradesh, Chhattisgarh, Gujarat, Punjab and Haryana are among the Indian states that are likely to witness a significantly higher number of heatwaves from April to June this year.
"A significantly higher number of heatwave days are predicted however, the country is also set to likely receive normal rainfall in April,” said IMD Director General Mrutyunjay Mahapatra. Normal to above-normal minimum temperatures are very likely over most parts of the country, barring some areas in northeast and northwest India and isolated pockets of the peninsular region, the IMD said.
Precipitation levels to go up in northwest
The IMD also predicted normal to above normal precipitation over most parts of northwest, central and peninsular regions, while below-normal rainfall is predicted in east and northeast India this year.
Narrowing down further, in regards to Mumbai’s weather between April to June, Colaba IMD official, Sushma Nair said that as the city falls in the Konkan belt, the probability of heatwaves in Mumbai in the coming months is less. “The heatwaves predicted over Maharashtra are most likely for Central and Vidarbha region in the state, meanwhile the moisture in the air over Mumbai will start increasing from April which will increase the hot-humid climate in the summer season,” said the official.
High temperatures were expected in March
High temperature degrees were mostly expected in the month of March for Mumbai, therefore the chances for the temperature to go above 39 degrees Celsius in the coming months is less, added the official.
On Saturday, Santacruz witnessed a minimum temperature of 22.0 degrees Celsius and a maximum of 31.6 degrees Celsius, with 71% relative humidity. Colaba experienced a minimum temperature of 24.1 degrees Celsius and a maximum of 31.4 degrees Celsius, with 73% relative humidity.

National Weather Service Honolulu HI
830 PM HST Sun Jul 21 2019
A trough of low pressure will pass by a few hundred miles to the
south of the islands during the next couple of days, spreading
clouds and showers from southeast to northwest across the island
chain through Tuesday. Drier weather and decreasing cloud cover is
expected by Wednesday. Moderate to locally breezy trades and typical
windward and mauka showers with the occasional leeward spillover for
the smaller islands will then prevail into next weekend.
Persistent surface high pressure far north coupled with a trough of
low pressure passing south of the islands are bringing moderate to
locally breezy trade winds to the islands this evening into early
Monday morning. There is also an upper level low northwest of the
area. It would be typical trade wind weather for the islands if not
for the upper level feature as well as the low level trough.
Moisture from the passing trough reached the Big Island earlier.
Meanwhile, airmass in the island vicinity is somewhat unstable due
to the present of that upper level low. Hence, thunderstorms did
develop over the Big Island earlier Sunday afternoon. Looks like
much of the unstable weather may just clip the extreme southern Big
Island with a slight chance of thunderstorm and locally heavy rain,
while rest of the islands will see trade wind weather, with some
enhanced showers affecting mainly windward and mountain areas. Winds
will be strong enough to carry some clouds and showers to the lee
areas of the smaller islands through early Monday morning.
This trough of low pressure will move almost parallel to the islands
through Tuesday. Thus, it will stay south of the main Hawaiian
islands. But then, moisture associated with this system will be
spreading northwest. In the mean time, the aforementioned upper
level low will be shifting east but still providing some airmass
instability to the area. Therefore, still expect much of the
unsettled weather will remain south and west of the islands Monday.
The only exception is the Big Island, where atmospheric conditions
will be unstable and moist enough to see a slight chance of
thunderstorms during Monday afternoon and evening. Rest of the
islands may also see an increase in clouds and showers.
The upper level low will be far west enough by Tuesday for more
stable atmospheric conditions to spread from the east, though Kauai
weather may still be under the influence of the low. Latest forecast
solutions have the bulk of the moisture just southwest of Kauai.
Thus unsettled weather may still affect western and southern coastal
waters of Kauai Tuesday. Rest of the islands will see a return of
the typical trade wind weather, with passing low clouds and showers
affecting mainly windward and mountain areas.
Latest GFS indicated a trough may deepen just northwest of the
islands by the middle of the week, with high pressure current far
north of the area moving to the northeast. Forecast solutions also
show high pressure aloft moving to near the islands over later part
of the week. Looks like the islands will see seasonal trade wind
weather for the most part by then, though wind direction may turn
slight southeast due to that possible deepening trough to the
A high will remain nearly stationary far north of the main Hawaiian
islands as a trough passes southwest of the area. The pressure
gradient between these systems will maintain locally strong east
winds over the area. AIRMET TANGO is in effect for moderate
turbulence below 8,000ft and this AIRMET will likely continue
Clouds and showers that developed over the slopes of the Big Island
and Maui Sunday afternoon will gradually dissipate. The low level
winds will carry scattered to broken low clouds over east sections
of the smaller islands. Isolated MVFR ceilings are possible over
these areas tonight, but we don't expect the ceilings to be
extensive enough to require AIRMET SIERRA for MTN OBSC.
An area of layered clouds and isolated thunderstorms associated with
the trough passing southwest of the area lies just south of the Big
Island of Hawaii. These clouds are expected to remains offshore
overnight, but moisture from this system may fuel heavy showers and
isolated thunderstorms over the Big Island Monday afternoon. AIRMET
SIERRA may be needed for MTN OBSC.
Fresh to locally strong easterly trades will continue through the
week as high pressure remains north of the area and weak low
pressure passes to the south. Stronger winds will remain across the
typically windier locations from Maui County to the Big Island due
to terrain accelerations. The current Small Craft Advisory through
Monday night will likely be extended into the week.
Heavy showers and a few thunderstorms will remain a possibility
across the waters around South Point of the Big Island overnight
into Monday, then over the leeward waters of the smaller islands
Monday through Tuesday night as the aforementioned area of low
pressure to the south tracks northwestward.
Rough surf will continue along east facing shores due to strong
onshore trades. A slight downward trend is expected for a brief
period Monday through Tuesday as upstream trades relax. A slight
uptick is expected once again Wednesday into Thursday as upstream
Surf along south facing shores will remain small through tonight,
then trend up late Monday through midweek out of the south-southwest
due to a recent system that passed near the Tasman Sea. Heights
should remain below advisory levels as this swell moves through and
peaks Tuesday. A south-southeast long-period swell associated with a
recent compact gale southeast of the Tuamotus will be possible
Thursday night through Friday. Surf will rise along exposed shores
but should remain below advisory levels.
Small Craft Advisory until 6 PM HST Monday for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
Island Southeast Waters.

Excessive heat warnings and heat advisories likely late this weekend into next week.
Will we hit 100°? I think there's a decent chance it happens, but let's not focus on that. The heat index may exceed 110°. With football practice, band, etc, this is a major concern for EVERYONE.
The upcoming heat is NOT record breaking and is very typical in Arkansas. However, we must always remember heat is the number 1 weather related killer. We want to get through this heat without anyone getting hurt. Please take care of yourself and your neighbors!
For the actual air temperature to hit 100°, we look for 3 things: complete sunshine, a ridge of high pressure centered on our region, and a dry ground. The ground may have dried up enough for it to happen. The ridge of high pressure will flex its muscles over the region starting Sunday, then move slowly westward by Wednesday. It will cool down a little, but probably not much at that time.
I hope the models are wrong, but it's looking likely we'll see some serious heat and humidity. Nothing unusual and nothing record breaking, but you don't need that to cause problems. Take care.


Gale force winds and bands of heavy rain are expected to buffet the country this week bringing possible surface flooding and damage to trees and powerlines.
A front moving up from the South Island tomorrow would bring a spell of strong winds and heavy rain with it.
MetService said from Wednesday a strong disturbed westerly flow would affect the country bringing the foul weather.
It was a similar situation to last weekend, MetService meteorologist Angus Hines said.
"A number of severe weather watches and warnings have been issued this morning to reflect the weather that is coming in the next couple of days."
A front would sweep east across the North Island early in the morning on Wednesday.
There was moderate confidence, a 40 per cent chance, of heavy rain from Kapiti northwards, and moderate confidence that northwest gales would be severe early morning from Wellington to the central North Island high country and the ranges of Gisborne and the eastern Bay of Plenty.
On Thursday another front was expected to sweep east on to the country.
There was a high confidence, 60 per cent chance, in heavy rain in Westland and Fiordland and a moderate confidence in the west from Taranaki southwards.
On Friday a strong westerly flow affected the North Island and there was moderate confidence in severe westerly gales there.
A heavy rain warning was in place for the Canterbury High Country until 8pm tomorrow, and for Westland until 6pm tomorrow.
A warning was also in place for Fiordland and the headwaters of Otago rivers and lakes until early afternoon on Tuesday.
Streams and rivers could rise rapidly and surface flooding a slips were possible in the rain, Hines said.
A strong wind warning was in place for Wellington and Marlborough to 11pm Tuesday and in place for Canterbury High Country until 5pm Tuesday.
That wind could be hazardous to motorcycles and high-sided vehicles and damage to trees and powerlines was possible, Hines said.


Sunny, Windy & Seasonable This Afternoon
Monday’s Forecast High: 66°F, Tonight’s Forecast Low: 48°F
After a cool, fall weekend, temperatures will be more seasonable today. Plenty of sunshine this afternoon with highs in the mid 60s. Winds are strong out of the south with gusts in the 30-40 mph range.
Clear to partly cloudy tonight, and not as cold. Lows will fall into the mid to upper 40s, which is where we should be for this time of the year.
Temperatures will warm even more Tuesday. Winds will still be breezy, but not as strong as today. Partly sunny tomorrow with highs in the low 70s.
There will be a very slight chance of a shower Tuesday night as a cool front moves through the Upper Midwest.
Behind the cool front, temperatures will be a few degrees cooler for Wednesday and Thursday. Highs will top out in the upper 60s to 70 degrees.
Winds will shift back out of the south and increase on Friday. These strong winds paired with sunshine will help temperatures warm well above average into the mid to upper 70s.
Warmer than average for the weekend with sunshine. Our next chance of rain arrives early next week.
Enjoy your day! –Michelle Poedel


2”-5” of snow fell today. While that doesn’t sound like a lot, the impact for this storm was higher because of the cold air!
With temperatures in the teens, every snowflake that fell accumulated on the roads. With the peak of the storm hitting during rush hour, numerous roads became congested and snow covered. But that’s over now! Snow is winding down. Shoveling aside, we get a prolonged break from the snow.
With this recent cold and snowy pattern, you would think a white Christmas was a given this year. Not so fast. A warming trend is underway that will slowly chip away at the snow on the ground. Wednesday will be partly to mostly sunny with high temperatures in the mid and upper 30s. 40s are likely Friday and Saturday. The warm up peaks Sunday with highs in the 50s and periods of rain. Temperatures will get back to average around Christmas time but little (or no) snow cover will remain.
Tonight: Lingering flurry. Low: Teens.
Tomorrow: Partly to mostly sunny, breezy. Not as cold as recent days. High temperatures in the middle to upper 30s.
Thursday: Partly cloudy, a bit milder. High temperatures in the upper 30s inland, lower 40s for the shoreline.
Friday: Increasing clouds, noticeably milder. Chance for showers late in the day or at night. High temperatures in the middle 40s.
Saturday: Early showers followed by some clearing. Showers redeveloping at night. High temperatures in the middle 40s inland, upper 40s for the shoreline.
Sunday: Periods of rain, foggy and very warm! High temperatures in the 50s statewide.


Well, I am going to have to eat some crow.
Back in early October, I unwisely predicted there would be 18 Category 4 or 5 hurricanes globally in the year 2007. At the time, there had been 14. Since then there has only been one more the incredibly devastating Cyclone Sidr bringing the global total to 15. And with the year almost out, at this point I don't see any chance of not being wrong in my prediction.
In fact and as we'll see barring some sudden dramatic tropical eruption, 2007 is going to turn out to be a below-average year for overall global intense hurricane activity. That's not to say there weren't some serious hotspots particularly the North and South Indian Ocean basins. But for anyone convinced that global warming is causing an increase in the intensity of the average hurricane, it's hard to make the case that 2007 serves as a data point in your favor.
To see that, though, let's first survey the total storm activity in all the major hurricane basins. My source for this data is Unisys Weather, but I have made a few corrections in places where that data seem incorrect (e.g., Cyclone Indlala is only listed as a tropical storm by Unisys when in fact it was a Category 4).
In the Atlantic and Northeast Pacific, where storms are tracked by the U.S. National Hurricane Center, I counted all storms that were given names (which occurs once the storms reach maximum sustained wind speeds of 35 knots 40 mph or higher, the cutoff for Tropical Storm status). For other basins, where there are multiple measurements used in classifying storms and multiple monitoring agencies, I am counting all storms in the Unisys database that had a maximum sustained wind speed of 35 knots or higher.
That process leaves you with the following numbers, as of Dec. 19, 2007:
Tropical Storm Tracks, 2007 Northwest Pacific Basin Unisys Weather
What can we read into these numbers?
Well, first off, the average total number of storms per year is generally in the 80-90 range, so there's nothing particularly noteworthy about 2007 in that respect.
However, when you come to the total number Category 4 and 5 storms, it's another story entirely. Here, the average per year is 17, and the record in one year is 25. By these lights, 2007 is definitely a below average year.
Granted, 2004, 2005, and 2006 were all above average, with 23, 22, and 19 Category 4 and 5 storms, respectively. So 2007 may just be a quiet anomaly. Moreover, there were a number of borderline Category 3/Category 4 storms this year, which might have been bumped up a category had they occurred in the Atlantic region.
But nevertheless, the official 15 storm total which, to be sure, could increase by the end of the year, but probably not by more than one storm at the absolute most clearly does not help the argument that global warming is intensifying hurricanes.
Next week I will go more in depth, and look in more detail at some of the most remarkable and troubling storms of 2007.

Fishermen cautioned of rough seas
December 3, 2019 02:55 pm
Due to the low-level atmospheric disturbance to the south of Sri Lanka, showery and windy condition is expected to enhance over south-eastern and southern sea areas, the Met. Department said.
Accordingly, active clouds can develop in the deep and shallow sea areas off the coast extending from Galle to Pottuvil via Hambanthota.
Therefore, the possibility for heavy thundershowers and sudden roughness, associated with sudden increase of wind speed up to 70-80 kmph in the above given sea areas is high.
Naval and fishing communities are requested to be vigilant in this regard, the department said issuing a special advisory for rough seas.
For Land areas:
Due to the low-level atmospheric disturbance in the vicinity of Sri Lanka (south of Sri Lanka),prevailing showery condition is expected to enhance over Northern, Eastern, North-central, Uva and Central provinces from tonight, particularly during December 04 and 05.
Very heavy showers above 150 mm are likely at some places in Trincomalee, Batticaloa, Ampara, Mullaitivu, Nuwara-Eliya, Badulla and Monaragala districts.
Heavy showers above 100 mm are likely at some places in North-Central, Sabaragamuva, Southern and Western provinces and in Matale, Kandy, Jaffna, Mannar, Kilonochchi and Vavuniya districts. (Anuradhapura, Polonnaruwa, Galle, Matara, Hambanthota, Kegalle, Ratnapura, Gampaha, Colombo and Kalutara).
General public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
Fairly strong gusty winds up to 55 kmph can be expected over the island particularly in North-Western, Southern, Central, Uva and North-Central provinces.


I have always been a big fan of statistics, especially after I took that valuable course back in my college days at Rutgers University.
I saw this press release from the Ohio State University in regards to statisticians using statistical analysis of different climate models in order to estimate projections of temperature changes and certainty for the years 2021 to 2070 across North America.
"One of the criticisms from climate-change skeptics is that different climate models give different results, so they argue that they don't know what to believe," says Noel Cressie, professor of statistics and director of Ohio State's Program in Spatial Statistics and Environmental Statistics. "We wanted to develop a way to determine the likelihood of different outcomes, and combine them into a consensus climate projection. We show that there are shared conclusions upon which scientists can agree with some certainty, and we are able to statistically quantify that certainty."
Using regional climate models' temperature values from 1971 to 2000 in addition to their projections for 2041 to 2070, the research team estimated that average land temperatures across North America will rise around 4.5 degrees F or 2.5 degrees C by 2070.
Through this analysis, the team also determined that there is a 97.5% probability that average temperatures will rise by at least 3.6 degrees F or 2.0 degrees C over a large area of North America by 2070. You can see those maps right here.
No surprise, the northeast part of North America in Canada is projected to see the greatest increase in temperatures over the winter with a rise of about 10.7 degrees F or 6.0 degrees C by 2070 as sea ice continues to diminish, allowing more of the sun's energy to be absorbed, instead of reflected back to space.
Also from the OSU release.......
Cressie cautioned that this first study is based on a combination of a small number of models. Nevertheless, he continued, the statistical computations are scalable to a larger number of models. The study shows that climate models can indeed be combined to achieve consensus, and the certainty of that consensus can be quantified.
Much more in depth discussion about this research can be found on the statisticians' website.
How did November 2014 rank in terms of global surface temperature?
Global extreme temperature anomalies are rising faster than average temperature anomalies.
People's perceptions of global warming are influenced most by their political orientation and not by actual changes in climate.
Current record-breaking sea surface temperatures indicate that the 14-year pause in ocean warming has ended, according to a new study.
Will 2014 end up as the warmest year on record?
New research tries show a better way of understanding what happens to the Earth under climate change.


AN ASSESSMENT OF SEVERITY OF ENVIRONMENTAL AEROSOL PARTICLES DURING PRECIPITATION
Keywords:Atmospheric aerosols, Biomass, Classification rule, Multinomial model, Precipitation, Severity index
Africa is one of the sources of biomass burning emissions. It is estimated that about 6 million tons of fuel per day is consumed in the southern hemisphere. Biomass burning has an important contribution on aerosol particle concentrations in the atmosphere. Efforts have been made to conduct research in Gaborone to monitor the concentration of atmospheric aerosols in atmosphere. These studies were mainly confined to measurement of concentration of aerosols and establishing a relation with determinants such as carbon dioxide concentration, biomass burning, and precipitation among others. However, very little seems to have been done in relating the empirical data to a mathematical model or to study quantitatively the impact of precipitation on the concentration of aerosols larger than 0.3?m in the atmosphere. In this paper we provide an objective criterion for classifying measurements on concentration of atmospheric aerosol particles and build a mathematical model that helps us to understand variations in weekly aerosol concentrations in terms of their severity. We also construct an index of severity which when applied to different seasons under the study period indicates that precipitation significantly scavenges atmospheric aerosols.

Air temperatures at Baltimore Washington International Airport in
March and April fluctuated mostly between 50-80 degrees F with frequent rain events.
According to the National Weather Service, this was the wettest April since 1983. The
maximum daily air temperature then warmed steadily from 51 degrees F (April 27) to 92
degrees F (May 7 and 8) with very little rain.

year and showed a gradual increase in the density of
minimum from 106 cells/milliliter on March 7 to 3551 cells/milliliter
on April 18. The sunny, warmer weather in late April and early May generated
a steep rise in the surface water temperature. The temperature rise
coincided with the significant bloom of Prorocentrum to 57,000

Reports from India are pointing to an intense Indian monsoon this year [Indian monsoon death toll soars], saying "the rain on Tuesday was the heaviest recorded in a single day in India... More than 65cm (26 inches) fell in Mumbai."
I just wanted to post this article as yet another reminder that global climate change doesn't just affect the temperature. As global warming progresses, it is extremely likely that regional monsoons will be affected (in different ways in different regions). Similarly, some studies suggest the intensity of monsoons, droughts, tropical and midlatitude cyclones will all be larger in a warmer climate, or at least that variability will increase.
This matters for more than forecasting weather. People's lives are at stake, especially for the millions of people (most of them poor, despite places like Malibu) who live in low-lying coastal areas that are impacted by seasonal inclement weather. In places like Mumbai (and Malibu, I suppose), severe weather events can cost millions of dollars in damages, affecting local and non-local economies. Climate change has far-reaching consequences, as you knew already.


Sneaky Warm and a Bit Too Dry: April 2008 Overview
New Jersey State Climatologist

May 2, 2008
Its cool, damp conclusion may have convinced many that there wasn't much of a surplus of heat or a dearth of precipitation in April; however it proved to be a mild, dry month. April temperatures averaged 53.0°, or 2.5° above the long-term average, making this the 12th warmest April since 1895 (see table below). Having the last four days come in below average was enough to knock it from the top 10. This is the 5th consecutive month of below average temperatures and makes 10 of the past 12 on the warm side of the ledger.
The warmest afternoon was the 18th, when temperatures were in the 80s statewide (even High Point), with the exception of coastal areas where temperatures stayed in the 60s. The 18th saw a diurnal temperature range of 51° in Hillsborough (Somerset County: max 87°, min 36°), while on the coast, Harvey Cedars' range was 11° (Ocean County: max 61°, min 50°). The morning of the 3rd was by far the coldest, with some northwest and Pinelands valleys in the mid teens and all but the immediate coast below freezing.
What was on its way to be a very dry month proved to be only a moderately dry one thanks to a general statewide soaking on the 28th (though as has been commonplace for the past year, the south didn't prove quite as wet as the north). Monthly precipitation totaled 3.08", or 0.85" below normal, making this the 44th driest on record. Without the rain on the 28th, the ranking would have been knocking on the door of the top 10 driest. But as seen with the temperatures, it takes a full month of observations and every day counts. Other days with notable precipitation in April include the 3rd-4th and 11th-12th. There was no measurable snow in the state during the month.

What is PM10?
“PM”, Particulate Matter, is not a single pollutant, but refers to a complex mixture of solids and aerosols of varying shape, size, and chemical composition and may contain many chemical species like organic compounds, inorganic ions, metallic compounds, elementary carbon, etc. So, these atmospheric particles are defined by their diameter for air quality regulatory purposes.
The inhalable particles that are less than or equal to 10 micrometers in diameter are collectively known as PM10, they tend to settle as they are heavier. Once released, they stay in the air for minutes or hours and travel as little as 100 meters to 50 kilometers. Also, examples of such coarse particles include construction dust, pollen, mold, etc.
Particulate matter PM10 is either directly emitted from a source (primary PM) or is formed through the chemical reactions of gases such as oxides of sulfur (SOx), nitrogen oxides (NOx), organic compounds, etc. in the atmosphere (secondary PM). Whereas, the natural sources of particulate matter are wind-blown dust from open land, pollen, spores, mold, dirt, soil erosion, and forest fires. Meanwhile, anthropogenic sources of PM10 include:
- Burning fossil fuels such as gasoline, oil, diesel, or wood,
- Also, waste-burning activities
- Dust emitted from unpaved and also the paved roads
- Crushing and grinding of rocks
- Also, uncontrolled construction activities
- Dust from factories, agriculture, and also from landfills
- Emissions from energy supply and industrial processes
- Metal and steel production as well as the reloading of bulk material
- Also, wear and tear of brakes and tires of vehicles
- Also, organic compounds released from industrial processes and motor vehicle exhaust
Permissible levels of PM10
The breakpoint concentrations describing the quality of air based on the PM10 concentrations for different countries are given below. In India, the daily average PM10 levels of up to 100 μg/m3 are considered satisfactory. The Air quality guidelines by the World Health Organization suggest a 24-hr mean of 50 μg/m3.
Breakpoints of PM10 (μg/m3)
Table: Breakpoints of PM10 (μg/m3)
|India (24-hr)||US (24-hr)||China (24-hr)||EU (8-hr)|
|AQI Category||Breakpoint concentration||AQI Category||Breakpoint concentration||AQI Category||Breakpoint concentration||AQI Category||Breakpoint concentration|
|Moderately polluted||250||Unhealthy for sensitive||250||Lightly Polluted||250||Medium||50|
|Very Poor||430||Very Unhealthy||420||Heavily Polluted||420||Very high||100+|
Health & Environmental Impact of PM10
The potential of particulate matter to affect human health depends directly on the size of particulate matter. The particles with < 10μm diameter generally pass through the nose and throat and enter the lung. PM10, although less of an immediate health concern than PM2.5 due to its size, is still small enough to pass through the nose and throat and enter the lungs.
When inhaled, PM10 deposits on the surface of the airways in the upper region of the lung, inducing tissue damage, and lung inflammation. It can irritate the nose, throat, and even eyes, short-term exposure to PM10 aggravates already present respiratory diseases such as asthma while long-term exposure can affect respiratory mortality. Sensitive groups of people such as children, elderly with chronic heart or lung disease, or people suffering from asthma are more susceptible to adverse health effects of particulate exposure.
The major environmental impacts of PM10 pollution are visibility reduction and deposition. Whereas, high levels of PM10 cause visible air pollution affecting the aesthetics of the surrounding environment. Additionally, the settling of the air-borne PM10 on plants, soil, and water ecosystems has harmful effects on them. The metal and organic compounds reduce plant growth and yield while the deposition of PM into water bodies affects its quality and clarity.
Atmospheric particles also affect the heating and cooling of the atmosphere. Some components of PM such as black carbon promote climate warming while some components such as sulfates and nitrates have cooling properties.
Possible corrective measures
The primary step is PM10 monitoring to identify the areas with high particulate levels or areas where air quality does not meet the PM10 national standards, In addition to this, the following corrective measures can be taken:
- Limit outdoor activities and close windows and vents during times of high air pollution.
- Avoid keeping your vehicle idle for so long.
- Avoid areas with traffic congestions, construction activities, or unpaved roads, breathing such polluted air daily also leads to health effects in the long run.
- Also, eliminate the use of the fireplace, wood stove, gas-powered lawn, or garden equipment.
- And also eliminate the open burning of leaves, trash, or other materials
Measurement methods of PM10 monitoring
Different working principles for particulate matter monitoring in the ambient environment are Gravimetric, TOEM, Beta Attenuation (BAM), and also Laser scattering
High-volume Gravimetric Method
The PM10 monitors based on the gravimetric principle take in the ambient air for 24 hours at a constant flow rate through a size-selective inlet that only allows particulate matter with an aerodynamic diameter of 10µm or less to pass through. Also, the collection of the particulate matter is on a pre-weighed filter at constant temperature and humidity conditions. Then after the 24-hour sampling period, the filter is conditioned again under the same temperature-humidity conditions and reweighted. Therefore, The difference in the weight corresponds to the mass collected on the filter, which along with the known flow rate, sampling period, and the total volume of the air sampled is used to calculate the PM10 concentration.
Tapered Element Oscillating Microbalance (TOEM)
It is a proprietary system for particulate matter monitoring, subsequently, the PM10 monitors based on TOEM determine the PM10 concentration by continuously weighing the particulates deposited on the filter attached to a hollow tapered element that oscillates in an applied electric field. Also, the oscillating frequency decreases with the accumulation of particulates on the filters. As a result thermal mass flow controllers constantly control and measure the flowrate of the PM10 monitor which along with the mass concentration, temperature, and other factors is used to continuously calculate the PM10 concentrations.
Beta Attenuation Monitor (BAM)
The PM10 monitoring based on the BAM principle measures the particle mass density using beta radiation attenuation, the particulates in the ambient air drawn into the PM10 monitor are deposited on a paper-band filter and exposed to beta rays (i.e. electrons with energies in the 0.01 to 0.1 MeV range) which get attenuated as a function of the particulate mass. As a result, the beta count reduces with an increase in the PM10 mass and is recorded by the detector and converted to concentration.
The PM10 monitor based on the physical principle of light scattering, also known as optical particle counter (OPC), measures dust particles illuminated by laser light at a 90° angle. Whereas, the light scattered from each particle is collected at approximately 90° by a mirror and detected by a photo-diode. This signal is then fed into a multi-channel size classifier where a pulse height analyzer is used to classify each pulse that is proportional to the particle size. As a result, the counts in the channel corresponding to PM10 are converted to the concentration of PM10.
Among all the above principles of PM10 monitoring, PM monitors based on laser scattering are typically found to be preferred for ambient air monitoring because they yield quick and accurate measurements and are inexpensive in cor
Oizom’s working principle for PM10 monitoring
Oizom’s DUSTROID is an online particulate monitoring system that measures the concentration of various particulate sizes ranging from 1 micron to 100 microns such as PM1, PM2.5, PM10, and PM100 in the ambient air. Our PM sensor works on the principle of laser scattering hence, the active sampling-powered sensor-based air quality monitor DUSTROID is deployed across several cities, campuses, and universities. They are also used for drawing actionable insights to tackle the rise in ambient PM2.5 concentrations. Also, refer to case studies on air pollution for more information.
5 reasons why PM10 monitoring is important:
- PM10 is a complex mixture of solids and aerosols of very small size that can easily pass through the nose and throat and also penetrate the lungs.
- Particulate matter is emitted into the atmosphere from processes such as combustion processes, cruising or grinding of rocks, and resuspension of dust and dirt from roads, soil, etc. They also form in the atmosphere from various chemical reactions of other air pollutants such as NOx and SOx.
- When inhaled, it irritates the eyes, nose, throat, and airways and can also lead to aggravation of respiratory diseases.
- PM10 monitoring is an efficient way to detect high concentrations of particulate matter and also prevent high-level exposures.
- Real-time monitoring of PM10 levels helps in calculating the air quality index to deliver health advisories as well as formulating an action plan to meet standards.

Clear & Seasonably Cool Tonight, Areas of Fog Possible Late -Bill Graul
Fog Could Again Impact the AM Commute on Wednesday
Tonight’s Forecast Low: 61F / Wednesday’s Forecast High: 87F…
It’s another really nice summer evening for outdoor plans. It will be clear tonight with seasonably cool lows in the 50s for most, but likely around 60F in La Crosse. Dew points will be a bit higher tonight, making it feel a little muggy… but not bad for this time of year.
Winds will be light, which could again lead to areas of fog late tonight into Wednesday morning… especially in the river valleys. Keep in mind this could impact the Wednesday morning commute for some of you.
Any fog that develops will quickly mix out by about 9 a.m. or so… then expect sunny to partly cloudy skies. It will be warmer Wednesday with highs in the 82-87F range, and a bit more humid too. A weak boundary will bring a small chance (only 10-20% at best) for an isolated shower or sprinkles in spots Wednesday evening.
Thursday and Friday will be a bit cooler with a mix of clouds and sun. Expect highs in the upper 70s to low 80s, with lower humidity as well.
Looking Ahead… Warmer and more humid for the weekend with highs in the 80s. Small chance of t-showers on Saturday, with Sunday looking mainly dry. A bit better chance for scattered showers and t-storms next Monday, then Tuesday and Wednesday look dry at this time. Highs will be in the low-mid 80s Monday, then upper 70s to around 80F Tuesday and Wednesday.
Have a great Tuesday night! -Meteorologist Bill Graul

Delhi's air quality in 'poor' category with AQI 235
The air quality in the national capital on Wednesday morning was in the 'poor' category with the overall air quality index (AQI) touching 235, according to the "System of Air Quality and Weather Forecasting And Research (SAFAR)".
Several areas in the national capital, including Delhi University, Pusa, Lodhi Road and Indira Gandhi International Airport (Terminal 3) recorded air quality in the 'poor' category with an AQI of 262, 249, 228, and 215 respectively.
The air quality at IIT-Delhi was, however, in the moderate category with AQI at 176.
The PM 2.5 and PM 10 levels were recorded at 101 in the 'poor' category and 192 in the 'moderate' category respectively.
The SAFAR in its bulletin said that AQI is likely to improve on February 19 and 20 due to high wind speed and strong dispersion.
"The AQI today indicates 'Lower end of Poor'. Low wind speed for the next three days (February 16, 17, and 18) is likely to reduce ventilation, and the AQI is expected to worsen to 'upper end of poor' or 'lower end of very poor'," it said.
The AQI in Noida (Uttar Pradesh) is in the 'poor' category with AQI at 273 and in Gurugram (Haryana) in the 'moderate' category with AQI at 148.
As per the government agencies, AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.


BOZEMAN – A pattern change is coming to Montana beginning Wednesday with a blast of snow and cold start Thursday.
High-pressure over the Pacific NW has diverted the Polar Jet Stream up into the Gulf of Alaska and dropping down through Alberta Canada into Montana. This will open the door for colder air to sink southward by the end of the week into the weekend. Temperatures will be slightly colder than normal this weekend but at this time we are not expecting extremely cold below zero conditions.
Several Pacific storms following the jet stream will add increasing moisture in the northerly flow aloft beginning Thursday with widespread snow likely by Friday. Snow accumulations are likely for both lower valleys and higher mountains thus plan on wintry travel conditions beginning Thursday afternoon through Saturday morning.
Other impacts from the pattern change will be increasing surface winds east of the divide. Along the Rocky Mountain front down into the Upper Yellowstone region near Livingston peak wind gusts 60 to 70 mph are possible.
There are High Wind Warnings and Wind Advisories up for central Montana tonight through Wednesday evening.


She’s not a hurricane yet, but TS Hermine might become one before making landfall tonight. Florida’s west coast is expected to get 15+ inches of rain. Then the storm will move up the east coast over Labor Day weekend. Source: weather.com
I haven’t written much about hurricanes on here because there hasn’t been much activity near me. There’s currently a hurricane in the Gulf of Mexico that is expected to make landfall over Belize and the Yucatan peninsula tomorrow.
The center of Earl was located about 150 miles east of Belize City, Belize, as Wednesday evening, with maximum sustained winds around 75 mph. Earl’s forward speed had slowed over the past 24-48 hours, moving west at 14 mph. Source: weather.com
Earl isn’t expected to affect the US.
Perhaps the best reason we haven’t had any storms is because of high pressure “bubbles” sitting over Texas and surrounding states. It’s believed that El Nino is the cause: shifting the jet stream far north and allowing high pressure fronts to stay put over the southwest US.
(CNN) Hurricane Patricia — the strongest hurricane ever recorded — weakened slightly Friday as it barreled closer to Mexico’s Pacific coast, with sustained winds decreasing to 190 mph and gusts to 235 mph, the National Hurricane Center said in its latest advisory.
We’re getting ready for the rain storm of rain storms. Hurricane Ike in 2008 was the last big storm to flood this area; Patricia could be 2 times as bad. Local weatherman is predicting 3-5 inches, but the national weatherman made it look like 12 inches. Only time will tell. We may be locked in for 2 days or it might be just some rain.
UPDATE 10-24-2015 10:00
More then half of Texas is in for a sizable amount of rain over the next couple of days.
It was just 4 years ago that Texas was facing the worst drought in over 100 years. This year we’ve had above average rain fall. It’s making a dent in the drought.

Sometimes it feels like feast or famine.
Most of the lakes around here are closed or partially closed due to flooding. Memorial Day will be a wash out for Lake Somerville.
I guess we’ll see how long this lasts.
This storm forced a change in plans for the Republican National Convention. The RNC was scheduled to open on Monday in Tampa, Florida, when Isaac turned north and started running parallel to Florida’s west coast. They delayed the start of the RNC until Tuesday, August 28, 2012.
Several news sources are saying that Isaac is cutting a path through the Gulf of Mexico that’s eerily similar to the catastrophic Hurricane Katrina, which devastated New Orleans and the region nearly seven years ago to the day.
Isaac’s potential landfall as a Category 2 hurricane as early as Tuesday prompted evacuations along a wide area of the Gulf Coast and sent people out to stock up on staples. As of 5 p.m. EDT Monday, Isaac remained a tropical storm with top sustained winds of 70 mph. Its center was about 255 miles southeast of the mouth of the Mississippi River, and it was moving northwest at 12 mph. Source: Fox News
UPDATE: Hurricane Isaac
As of this afternoon, Texas A&M Aggies postponed this weekend’s football game with Louisiana Tech until October 13. It is best that people don’t travel to Ruston, LA (north central Louisiana), with Isaac approaching.
Isaac, a massive storm spanning nearly 200 miles from its center, made landfall at about 6:45 p.m. near the mouth of the Mississippi River. But it was zeroing in on New Orleans, about 90 miles to the northwest, turning streets famous for all-hours celebrations into ghost boulevards. Source: Fox News.
Texas isn’t the only place affected by heat and drought.
August was yet another busy month for global weather extremes. Highlights included record-busting heat and drought (again) in the south-central portions of the U.S.A. The climatological summer of June-August was the 2nd warmest since accurate measurements began in 1895. An intense heat wave also affected southern Europe in mid-month. Severe tropical storms lashed the eastern seaboard of the USA (Irene) and the Philippines and Japan. Torrential rains caused devastating flooding and landslides in Nigeria and Uganda. But the 2nd most important extreme weather story (2nd to the USA heat wave and drought) was the record cold wave and blizzard that hit New Zealand on August 14-15.

This drought and summer-heat is still going, and may continue until summer 2012. It did cool off last week though – lows in the mid-50’s, highs in the low 90’s – but we’ve only seen 1 inch of rain since August 1. That cool off is 2 weeks ahead of schedule. Usually we have a cool spell during the 3rd week of September.
Since January 1, state and local firefighters and crews from across the country have battled 18,887 wildfires over more than 3.5 million acres in Texas, according to state officials. Source: More wildfires erupt in Texas as it faces worst dry spell since 1895 – CNN.com.
Back in June I reported about Global Weirding and the number of counties in exceptional drought. Well, as expected, the trend continued into September. As of September 6, 81% of counties are in exceptional drought – the worst on the Drought Monitor’s scale.
See how fast wildfire spreads – Texas Parks and Wildlife
Almost two years after the drought of 2009, Texas is worse off than ever before. This summer, there are almost 4 times as many counties experiencing “exceptional” drought than in 2009 and almost 2 times as many than in 2006.
Just how hot is it? On May 25 – 27 days before the start of summer – we reached 100° F in Brazos county! If that’s a trend, I expect 45 – 60 days of 100+ degree days this summer. That is insane hot!
To our relief, it has rained and we got maybe 1/2 inch the last two nights. That will probably prolong the grass’ life another week or two. Check back in September, Texas might be in Dust Bowl 2.0. Meanwhile, crops and livestock are holding on for dear life.
To compound the trouble – or as a result of drought – Texas has experienced the worst fires ever too. More than 2 million acres have burned and it is only June – we have at least 90 days of dry, hot conditions ahead.
The tinder-dry conditions in Texas have spawned thousands of wildfires that have killed two firefighters, scorched about 2.3 million acres and destroyed about 400 homes since November. Source: Severe drought in Texas worst in map’s history | Star-Telegram

The latest weather alert from the Icelandic Met Office presents a difficult picture for the entirety of North Iceland, but conditions should mercifully improve by early tomorrow morning.
From the northern shore of Snæfellsnes, over the Westfjords, and across the entire northern coast of Iceland to the northeastern tip, one forecast prevails: gale force winds coming in from the north at speeds from 15 to 23 metres per second.
This is challenging enough to contend with in itself, especially if one is driving near mountains, where gusts are considerably stronger. However, as there is already plenty of snow on the ground in the region and, in some cases, more snowfall being forecast, poor visibility and deteriorating road conditions can also be expected.
Fortunately, these conditions are only predicted to persist until very early tomorrow morning, at which time it will likely clear up enough to make road travel safe again.

Wildfires to impact air quality in the Midwest
(ABC 6 News) – Smoke from wildfires in Oregon, Washington, and Idaho is expected to catch some upper-level winds, known as a jet stream.
This jet stream will guide the smoke toward our area. As the smoke gets farther away from the fires, it will become less and less dangerous for our health, but that’s not all.
Nick Witcraft is an air quality forecaster with the Minnesota Pollution Control Agency. He lists another reason. “We’ll probably have some pretty sunsets over the next few days, you know the deep red sunsets.”
The smoke in the sky will decrease the brightness of the sun, giving it a more red/orange color to the visible eye. Some smoke is already up in the air over our area. If you’re worried about being affected by the smoke, it will only impact a select few. Witcraft mentions who it will impact.
“Extremely sensitive people. We don’t expect a repeat of last Summer when we had the major occursion of smoke.”
If you have asthma or other respiratory problems, take it easy if you start to cough or have shortness of breath.
Also, northern Minnesota is expected to be impacted more than southeastern Minnesota.
Friday and Saturday are the big days to watch out for in our area. We’re expected to see the peak of the smoke immediately behind an incoming cold front.
According to airnow.gov, the air quality index should be 150 or more before it affects the general public; whereas we will not even hit 100 this time around. We will see a gradual improvement in air quality heading into next week.


Today we will have a rather cloudy day with showers around. There could also be some rumbles of thunder at times. High temperatures today will be in the upper 70s to lower 80s. Winds today will be from the south between ten to fifteen miles an hour. Tonight temperatures will dip into the 60s. Tonight the sky will slowly celar.

This is part of a frontal boundary that is stuck here as Tropical Storm Henri (‘ahn Ree’) makes a turn up the east coast.
Henri is expected to become a Hurricane and make landfall on New England.
Beaches: Rip Currents and periodic storms will make this a weekend to watch but not go in the water.
Forecast Track From The National Hurricane Center
The trend to the west now pushed a landfall on Rhode Island on Sunday.
Wave Animation (ECMWF Model)
The highest waves will be well offshore from Delmarva, but will create Rip Currents. The path of the storm is expected to make landfall on Rhode Island or Massachusetts.
Rip Currents will be a concern for a few days. Some improvement in the sky is expected on Sunday.

A Weaker But Still Dangerous Hurricane Dorian Makes Landfall On North Carolina’s Outer Banks
This Beasley Best Community of Caring report urges you to donate to efforts to help the Bahamas after the devastation of Hurricane Dorian. Read more below and please consider donating to Red Cross efforts HERE.
After causing major damage in the Bahamas, Hurricane Dorian has made landfall in North Carolina. On Friday (Sept. 6), Dorian, now a Category 1 storm with 90 mph hurricane force-winds, made landfall over Cape Hatteras, N.C. in the Outer Banks, according to the New York Times. After missing Florida and Georgia, Cape Hatteras marks Dorian’s first landfall on U.S. mainland.
While Dorian has lost strength in recent days, the Associated Press warns that the storm is still dangerous. On Thursday, North Carolina experienced 15 tornados, according to CBS News. North Carolina’s coast is already getting battered by torrential rain and the barrier islands are facing “historic water levels.”
The storm surge on the Outer Banks could reach the heights of a one-story building, according to forecasters. “Do not let your guard down,” Dare County emergency managers warned those who chose to ride out the storm, per the AP.
Dorian is expected to remain a hurricane as it moves up the U.S. east coast this weekend, but its hurricane-force winds are not expected to reach land. The Weather Channel reported that a tropical storm warning has been issued for southeast Massachusetts. Hurricane warnings have also been issued for parts of Canada.
Earlier this week, the storm brought devastating damage to the Bahamas, killing at least 30 people and demolishing countless homes. AP reported that at least four people in the southeast have died in preparation of the storm.


As fire weather conditions rise across the Southwest, truckers may run into road closures, low visibility due to smoke, and a high risk of rollovers.
Most of the large wildfires are in New Mexico — five of them, according to the Inciweb interactive map. Sections of at least 12 state highways are still closed due to these fires, especially in the Santa Fe and Las Vegas areas.
Much of the Southwest, from California to Texas, has been stuck in a long-term drought, making areas prone to wildfires. Periods of windy conditions have fanned flames out of control at times, especially in New Mexico.
The largest wildfire in the country is the Hermits Peak fire near Las Vegas, New Mexico. As of Sunday night, it had grown to more than 176,000 acres and was 43% contained. Crews made containment progress over the weekend, but they will have to battle high winds again early this week.
The National Weather Service is forecasting gusts of 60 to 70 mph Monday, and possibly Tuesday, for many parts of New Mexico, Colorado, northern Arizona and southern Nevada. Isolated spots could see gusts up to 80 or 90 mph.
Daytime humidity will be extremely low, less than 10% in many places, adding to the chances that new fires may pop up.
Fire weather conditions will spread into the Plains too, mainly in northern and western Texas, western Oklahoma and western Kansas. Wind gusts won’t be as strong as in the Southwest — 40 to 50 mph — but this is enough to cause issues. Thunderstorms will likely hit these areas Tuesday, so lightning strikes could spark fires.
The NWS has issued red flag warnings, high wind warnings and wind advisories across all the areas previously mentioned.
Besides the possibility of reduced visibility due to smoke and blowing dust, drivers will face a high risk of rollovers because of the winds.
Major lanes of concern
- Interstate 10 from Tucson, Arizona, to Fort Stockton, Texas.
- Interstate 20 in Texas from Abilene to the I-10 junction.
- Interstate 25 from Las Cruces, New Mexico, to Denver.
- Interstate 40 from Needles, California, to Amarillo, Texas.
- Interstate 70 from Denver to Hays, Kansas.

Weather Blog: Weekend rain chance looming
Thank you for stopping by the Weather Watch 12 blog! A gorgeous stretch of fall weather continues across the Midwest through Friday. In today's blog we discuss a rain threat this weekend and look ahead to clues of the new LRC weather pattern.
Let's start by fast forwarding to the end of the work week. Wednesday and Thursday will bring suntastic weather conditions to Wisconsin with highs inland in the low to mid 70s, and lakeshore areas staying in the 60s.
High pressure(big blue H) on the map below will keep us dry and sunny today and Thursday. This high slips east and is located near New England at 7am Friday morning. The map below also shows a cold front entering the upper Midwest. This front will signal the next chance of rain for southeastern Wisconsin.
If you have outdoor plans this weekend make sure to have a plan 'B' ready on Saturday. As of this writing the best chance for showers or thunderstorms will be Saturday afternoon or evening. The band of showers looks to be fairly narrow, and would not last all day.
The GFS computer model(one of many we use) shows total rainfall between 7am and 7pm in a narrow band from the U.P. of Michigan south through southeast Wisconsin. The darker green shade over Milwaukee represents rainfall of 0.25" to 0.50".
The band of showers looks to develop near Madison and move east. Right now rain cannot be ruled out for the Badgers homecoming game at 2:30pm, but hopefully the rain will miss Madison or move east by kickoff.
Finally, I want to provide a quick LRC update to those following along with the new weather pattern. Remember, the weather pattern that sets up from roughly October 1 through November will cycle and repeat through next summer. Each trough or storm system holds clues to the type of winter we may have in Wisconsin.
One important clue was the large storm system that brought severe weather and a blizzard to the Midwest and Plains this past weekend. The 500mb map below shows the position of the upper level low pressure area on Sunday, October 6. Keep in mind using the LRC we look for the trough axis. In the case below the trough axis would run from say International Falls, MN south to north Texas.
If a long term long, long wave trough sets up over the Midwest it may mean an active winter for some. Keep in mind this was just one part of the pattern and we need to see how the next 4-6 weeks play out before making the winter forecast.

Have a great day!


Winter Storm Electra will bring more snow, heavy for some, this weekend.
Rain showers early with overcast skies later in the day. High near 40F. Winds NNW at 10 to 15 mph. Chance of rain 80%.
Mainly cloudy. Low around 25F. Winds NNW at 10 to 15 mph.


Weekend storm could be a doozy
Travel could be "difficult to impossible" this weekend in the Red River Valley, the National Weather Service said Thursday as a major winter storm threatened to dump sleet, freezing rain and 8 to 14 inches of snow on the region.
Senior meteorologist Dave Kellenbenz said the prolonged storm will start tonight and continue on and off through Monday morning.

#2: Hurricane Beulah (1967): 115 Tornadoes
Path of Hurricane Beulah in September 1967.
Hurricane Beulah produced 115 tornadoes in southern Texas over a three-day period from Sept. 19-22, 1967.
The worst damage occurred in the community of Sweet Home in Lavaca County, according to a paper written on Beulah's tornadoes in 1970. Four of the five deaths occurred in this location.
Beulah also packed damaging winds, storm surge flooding and torrential rainfall that caused widespread flooding in southern Texas.


There’s a freezing rain warning in effect in and around Burk’s Falls and South River. Environment Canada says a warm front will move into the region from the south tonight causing two to six hours of freezing rain. Up to five millimeters of ice will accumulate. The freezing rain should end sometime overnight. This could cause for some really slippery conditions on the roads and highways. The weather agency says you should also prepare for power outages if you live in the area.

“The subject chosen by the World Meteorological Organization (WMO) to celebrate the World Meteorological Day in 2014 proves once again the constant effort of this organization to get involved actively in the life of human society. The young people of today are those who will benefit of the great progress achieved in the field of understanding and forecasting of the weather and climate evolution. At the same time, taking into account the present evolution of the Earth climate
towards Global Warming, it is necessary for the young generation to know as much as possible about the complexity of the climatic system, including the issue of climate change.
In his message, delivered on the occasion of the World Meteorological Day 2014, Michel Jarraud, Secretary-General of WMO, underlines that nowadays there are approximately one billion people aged between 15 and 24. About 85% of them live in developing countries, facing a variety of problems. Therefore, the Secretary- General of WMO says in his message: „…Yet many young people still suffer from poverty and discrimination, inequality and exploitation; many of them still lack access to education, health and other basic services. These problems are exacerbated by the hazards of climate change and extreme weather, which characterize the lives of young people today and will have an even greater impact in the decades to come. Atmosphere and ocean temperatures continue to increase, ice caps and glaciers around the world are steadily declining, sea level is rising and a number of extreme weather and climate events are becoming more frequent and/or more intense”.

Alex Kubicek started Understory after he received a master’s degree in atmospheric science. His lifelong passion of weather drove him to create awarding winning curriculum for Weather and Climate 101 at UW-Madison, receive “Outstanding M.S. Thesis” for his work on cloud microphysics and hail formation and now revolutionize the weather space with next generation weather stations. Kubicek has led Understory through an accelerator program, a hardware seed stage, an institutional seed financing of $2 million led by True Ventures and a Series A financing of $7.5 million, led by 4490 Ventures and with strategic participation by Monsanto.
Understory is a weather data analytics company that builds, deploys and harvests data to provide companies with empirical ground-truth weather data. Unlike any other solution, Understory deploys dense ground-based weather stations with technologically advanced sensors that detect and deliver 3,000-plus measurements per second. The heart of Understory’s solution is the weather station, which features a revolutionary design that is much more responsive and reliable than current weather stations. The weather station behaves like a dedicated scientist taking real-time measurements out in the field for weather events, including hail, wind, rain, as well as recording temperature, barometric pressure, humidity and derived measurements such as wind chill, heat index, sea level pressure and wind gusts. The station combines sensors that detect and report weather data on a second-by-second basis. It is the only type of weather station that delivers real-time data on the size of hailstone impacts. The ability to measure hail, wind and rain without any moving station parts in real time is what makes the weather station revolutionary. The temperature, pressure, and humidity instruments are standard technologies that have been integrated with onboard electronics for data management.


It’s going to be another beautiful day in the South Bay.
In fact, the entire week is expected to be mostly sunny with temperatures in the high 70s and low 80s, according to the National Weather Service. Today in San Jose, forecasters predict a high of 79 degrees, with an overnight low around 56.
It will cool down a few degrees as the week progresses, according to the weather service, then warm up again in time for the weekend. Saturday, highs in the low to mid-80s are predicted.

Good afternoon everyone!
Analysis of global models this morning indicate models have backed off on development in the Caribbean Sea, with the exception of the CMC GGEM. The CMC indicates a closed low, then depression south of Jamaica taking shape around Nov. 04 2013. Albeit this is the only model now showing any type of development, I cannot safely rule this out, based on the current wind shear forecast that shows upper level winds beginning to become more conducive for development in the eastern Caribbean in about 72 hours, with a fairly developed upper level anticyclone moving westward as time advances in the forecast period. This would also coincide with a brief return of an upward motion phase of the MJO, reaching its peak in about 4-5 days in Octant 1 based on the GFS and ECMWF MJO Multivariate Index forecast.
GFS MODELS MULTIVARIATE INDEX FORECAST
Satellite loop imagery doesn’t really indicate anything of any organization this afternoon, which would tend to cause a bit of skepticism on my part and to the layperson. However, upon processing the various areas that MAY be a potential trigger for development, the area in the far eastern Atlantic seems too far east to slide into the central Caribbean for development, and the area of clouds near 8.0N;47.0W does not appear to have any vorticity. My thought on this is, if one watches the current satellite loop carefully, a large area of cyclonic turning is noted over extreme northern South America near 10.0N;65.0W. This would be associated at the extreme southern portion of a trof axis that extends into the ITCZ.
CATL SATELLITE LOOP IMAGERY
Analysis of current and forecast steering layers maps indicate a weakness in the subtropical ridging north of the Leeward Islands which appears to be enough, in that this area may be moving north of due west. Further into the forecast in about 48 hours, the upward projection of the steering noted in the current layer mean shifts west and becomes more pronounced toward the central Caribbean, as a deep layer trof sets up off the Eastern Seaboard. Based on these factors, I do have the tendency to believe the area mentioned could very well be the trigger for possible development in about 4-5 days.
I will continue to monitor the Caribbean Sea over the next 96 hours.

Last week’s forecast didn’t turn out exactly as forecast, but the cold air did finally arrive; it just took a couple of extra days to show up. As we’ve seen several times this winter, warm Pacific air won out over colder arctic air, at least for a little while. The main systems developed as expected but the second low, which was to help usher in the colder air, ended up being pushed farther north by the mild air, which delayed the arrival of the cold air.
This forecast period will start off with plenty of sunshine and relatively cold air as a couple of areas of arctic high pressure slowly slide southeast across our region. The cold weather looks to stick around until about Thursday, with daytime highs in the -10 to -14 C range and overnight lows in the -18 to -24 C range. By Friday the high will have moved off to our southeast and we’ll see a southerly flow of milder air begin. Along with the milder air, we’ll see increasing clouds with maybe the odd flurry. These clouds look like they’ll stick around all weekend as warm and cold air battle each other for dominance.
For the most part, it looks like we should stay on the warm side of this battle, with daytime highs expected to be around -4 C and overnight lows around -10 C. Early next week the weather models show a large area of low pressure developing over the western U.S. This low is then forecast to move toward southern Manitoba by Wednesday or Thursday. Confidence in this storm system is low. Should it develop, we’ll see plenty of warm air move in ahead of it, with rain or showers developing by Wednesday. As colder air works into the system the rain will change to snow, with the best chances of significant snow being over western regions.
Usual temperature range for this period: Highs, -12 to 0 C; lows, -25 to -8 C.
