TUCSON - Isolated storms wrapped the work week and the trend continues into the weekend.
Some big rain makers developed this afternoon and evening causing some flooding issues for portions of southern Arizona, according to Meteorologist John Patrick. Rainfall rates over an 1" in the Nogales area led to a flash flood warning this evening and strong storms pushing out of the Catalina Mountains brought heavy rain to the Oracle area. A rain gage just outside of Oracle measured 0.71" and Nogales rain gages were between 0.47"-1.15".
A similar set up in the atmosphere is in place tomorrow for little change in the storm threat. Far eastern Arizona could see a mountain thunderstorm or two but will be limited by drier air. The moist Monsoon air will continue to sit west of a Tucson-Nogales line where the best chance for isolated storms sit. Enough moisture will hang around the region to get isolated afternoon storms firing up through the holiday weekend.
Daytime highs expected to remain slightly above average through the weekend. Tucson will hover right around the 100 mark through early next week. A slight downturn in the temperatures is forecast for the middle of next week with highs dropping into the mid 90s.
