As expected, the brief Monsoon break is coming to an end.

Ample moisture and a mid-level disturbance leads to scattered storms today. Rain chances range from 40% for Metro Tucson to 50% chance along the border and in the mountains. Morning clouds could limit the strength & coverage of storms. If sunshine breaks out, rain chances & the severe weather threat will increase. Prime time for metro storms looks to be 2-8 PM.

Today’s Monsoon Prediction Index is 5 out of 10 for Tucson, indicating a moderate risk of heavy rain, gusty winds and blowing dust.

Depending on morning cloud cover, tomorrow could see another round of scattered storms. Latest data suggests Thursday’s storm chances decrease from 50% to 20% by kickoff time for the Arizona football season opener.

Isolated storms return to start the Labor Day weekend, with some tropical moisture increasing the thunder threat to the scattered variety on Monday.
