Weather term ‘dry lines’ explained
Texas A&M University’s Department of Atmospheric Sciences

Q: You often hear the weatherman talk about a “dry line.” What is it?

A: Simply put, a dry line is very much like a cold front, said Brent McRoberts of Texas A&M University.

“It’s sort of a boundary between ver y humid air and air that is dry,” McRoberts explained. “The difference between a cold front and a dry line is that the temperature on either side of a dry line doesn’t var y much, as opposed to a cold front, where the temperatures can vary a great deal. The advances of dry lines can adversely affect the weathe in your area as they pass through.”

Q: Does a dry line mean rain is coming?

A: Ver y of ten, that is the case, McRoberts added.

“Clouds often form along dry lines during the afternoon and these can grow into thunderstorms,” he said.
