A thunderstorm is considered severe if it produces hail at least 1 inch in diameter or has wind gusts of at least 58 miles per hour. Every thunderstorm produces lightning, which kills more people each year than tornadoes or hurricanes.
The mean of 1 hour and 10 hour fuel moistures are less than 10% in combination with the following weather conditions. Relative Humidity <=20%Winds 10 – 14 mph. Wind speed and relative humidity ratios have different criteria.

One thought is that the water in Cumulus Clouds becomes large and heavy as the cumulus cloud grows in size. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Cool dry air starts to enter the cloud as the raindrops start falling through the clouds. The phenomenon of downdraft takes place., and more items.
What do thunderstorm clouds look like?
Thunderstorms can look like tall heads of cauliflower or they can have “anvils.” An anvil is the flat cloud formation at the top of the storm. An anvil forms when the updraft (warm air rising) has reached a point where the surrounding air is about the same temperature or even warmer.
Wall clouds form under the rain-free base (bottom) of cumulonimbus clouds. It takes its name from the fact that it resembles a dark gray wall (sometimes rotating) that lowers down from the base of the parent storm cloud, usually just before a tornado is about to form. In other words, it is the cloud from which a tornado spins.
