Portions of the Sonoran Desert have a decent shot at storms this afternoon.

High pressure near the Four Corners helps guide in Monsoon moisture. Rain chances today sit at 20% for Metro Tucson as highs peak in the upper 90s. Areas south and east of the Old Pueblo stand the best chance of storms. Primetime for thunder today looks to be 2-7 PM.

Tomorrow could be the most active day out of the next 7 for the Monsoon. Expect a 30% chance of storms in Tucson, increasing to 40% for Santa Cruz & Cochise Counties. Daytime highs reach the mid 90s, running a few degrees below average for early September.
