Dryline

By

Drylines and Tornadoes
The Storm Prediction Center
Definition: Dryline is a term used to describe the formation of a moisture boundary between warm, dry air and warm, moist air. A dryline is one type of weather front. In the Central Plains of the United States, dryline formation often leads to the formation of severe thunderstorms and the potential for tornadogenesis.

The passage of a dryline typically means there will be a sharp drop in humidity in the area. In the United States, eastward moving dry air clashes with the moist air from the Gulf region.
