Dry thunderstorm

A dry thunderstorm is a thunderstorm that produces thunder and lightning, but where all or most of its precipitation evaporates before reaching the ground. Dry lightning refers to lightning strikes occurring in this situation. Both are so common in the American West that they are sometimes used interchangeably.

Dry thunderstorms occur essentially in dry conditions, and their lightning is a major cause of wildfires. Because of that, the United States National Weather Service, and other agencies around the world, issue forecasts for its likelihood over large areas.
