TUCSON - Scattered storms stay west to start the weekend.
Abundant cloud cover for southeast Arizona limited storm potential for Tucson and points east today, according to Meteorologist John Patrick. In west central Pima County where sunshine started the day storms fired up and left behind heavy rain and strong wind gusts. A Flood Warning remains in effect for southern Pima County until 10:45pm this evening.
Enough moisture hangs around into Sunday to once again support scattered storms. Best chances look to remain west of Willcox-Bisbee line with storms capable of dumping very heavy rain and packing strong wind gusts. Temperatures look to remain below average for the sixth straight day as we wrap the weekend in the low to mid 90s.
An upper level disturbance that is sitting over the Baja peninsula is forecast to move over Arizona on Monday and Tuesday increasing our storm chances. As this low interacts with abundant Monsoon moisture expect flooding to be an issue to start the work week. By mid week westerly flow takes over and starts to filter in drier air shutting our storm chances down altogether by Thursday.
