TUCSON - Impressive storms bring heavy flooding rains and strong wind gusts to wrap up the weekend.
Moisture and heat combined for great instability in the atmosphere to really get thunderstorms going this evening, according to Meteorologist John Patrick. Radar estimates had portions of midtown Tucson receiving over an inch of rain in a very short period of time. This amount of rain filled up the streets and lead to curb to curb flooding stalling out numerous vehicles around town. Officially at Tucson International we picked up 0.21", the most so far in one day for the month of August. Our Monsoon total is now up to 4.87" from June 15 through today still nearly an inch above average. The storms also brought impressive wind gusts with the University of Arizona campus reading 58mph.
The storms have moved off into rural portions of Pima County for the night but a stray shower or two is still possible for the metro throughout the night. Spotty storms are in the forecast to start the work week as one or two could swing back into the Old Pueblo. The Monsoon activity picks up once again for the middle of the work week as an upper level disturbance moves into Arizona.
