Tucson Region

Jimmy's forecast

Tucson, Arizona | Published: 08.30.2008
Low pressure aloft over Sonora, in combination with a deep trough over the Great Basin, will keep us in a very active monsoon pattern through this weekend. Drier air will move in from the northwest by the middle of next week, possible putting a dagger in our summer monsoon.
