Dry Thunderstorm

Dry thunderstorms are most common in the western portion of the United States during the summer. They occur when the rain produced by thunderstorms falls through a substantial layer of very dry air which evaporates the precipitation before it reaches the ground.
Dry thunderstorms are notable for two other reasons: they are the most common natural origin of wildland fires, and they can produce strong gusty surface winds that can fan flames.
