Thunder rolls heading into the weekend.

While steering winds aloft are weak, ample moisture and instability should support scattered storms today. Tucson stands a 30% chance of storms between 1-7 PM, while areas east of the metro have a 50% chance of storms. Highs reach the upper 90s in the Old Pueblo this afternoon.

Today’s Monsoon Prediction Index is 4 out of 10 for Tucson, indicating a moderate risk of gusty winds and locally heavy rain.

Isolated storms are expected tomorrow, with scattered storms returning Sunday through the first half of next week. High pressure over New Mexico supplies deeper Monsoon moisture, leading to a 40% chance of storms Monday and Tuesday.
