original: They are most often cyclonic, that is, associated with a localized low-pressure region within a severe thunderstorm.
simplifications: The most often in the shape of a cyclone, this is when there is a tightly packed area of low pressure that is inside a very bad thunderstorm. They are most often cyclonic. This means they are part of a low-pressure area within a severe thunderstorm. They are most often cyclonic. That means it is associated with a localized low-pressure region inside a severe thunderstorm. They are most often cyclonic. In other words, they are associated with a limited low-pressure region within a severe thunderstorm. They are most often cyclonic. They are usually associated with a localized low-pressure region in a bad thunderstorm. They are usually associated with a contained low-pressure region inside a heavy thunderstorm. They are most often cyclonic. Cyclonic means having a localized low-pressure region within a severe thunderstorm. They are spin like a cyclone, and tied to local low-pressure areas within a bad thunderstorm. They are most often cyclonic, i.e. equated with a localized low-pressure region within a severe thunderstorm. They are most often like a storm, that is, associated with a localized low-pressure region within a severe thunderstorm.
