Severe Thunderstorm

Formation

There are three qualities needed moisture in the air, warm air, and an updraft. The warm air and moisture form a cumulonimbus cloud that gets pushed by the updraft into the atmosphere and a low pressure system. To be classified as a severe thunderstorm it must have either hail, 75.5mph winds, or a tornado contained within the storm.
