Forecast models indicate storms will come into Metro Phoenix from the east and northeast between 5 p.m. and 8 p.m. Thursday evening. The Storm Prediction Center has much of Arizona at a marginal risk for severe weather, including Metro Phoenix. The main threats with storm development for the Valley will be dust, damaging winds, flooding and lightning. Storms will generally be slow-movers as the move west-bound and southwest-bound.

Depending on how much activity develops in the Valley Thursday will help determine how much storm activity we see Friday and Saturday. Moisture remains in place for storm chances in the Valley both days before a slightly drier air mass moves into southern Arizona Sunday.

For Phoenix Thursday, look for a high of 103 with a 30 to 40 percent chance of evening storms. The low Friday morning will be 82 with a high of 101 Friday and a 20 percent chance of evening storms. Storm chances remain between 20 and 30 percent Saturday and Sunday. Highs this weekend will be between 101 to 105.
