A dry thunderstorm is a thunderstorm that produces thunder and lightning, but where all or most of its precipitation evaporates before reaching the ground.[1]Dry lightning refers to lightning strikes occurring in this situation. Both are so common in the American West that they are sometimes used interchangeably.[2]
Dry thunderstorms occur essentially in dry conditions, and their lightning is a major cause of wildfires.[3][4][5] Because of that, the United States National Weather Service, and other agencies around the world, issue forecasts for its likelihood over large areas.[4][6]
