1. Forms of Severe Weather

2. Thunderstorms Occur when warm, moist air rises quickly
Forms cumulonimbus clouds
Drops collect, fall as rain, causing downdrafts of air (heavy winds) as well

3. Lightning Rapid rising of air causes clouds to build up charge
When charge jumps from cloud to cloud or from cloud to ground, it makes a lightning bolt
Heats air to around 30,000°C (hotter than the sun)
Quickly expanding air is heard as thunder

Occurs along fronts
Wind blowing at different speeds causes rotation to start
Combine with an updraft of air, you have a tornado
