The winds at the <u>700Mb</u> level are the steering mechanism for air mass thunderstorms.
Thunderstorms are severe, short-term weather hazards most often associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusts. Thunderstorms are formed when a layer of warm, moist air rises into the colder regions of the atmosphere with large, fast updrafts.
All thunderstorms cause lightning. This is one of the top three causes of weather-related deaths in the United States. In fact, lightning kills about 50 people each year. Thunderstorms can also cause hail, tornadoes, and floods. In some cases, hail is the size of a baseball and can travel at speeds of 100 mph.
