The Storm Prediction Center has placed Phoenix and southern Arizona under a slight risk for severe thunderstorms late Monday night and overnight, including the I-10 corridor between Phoenix and Tucson, according to Arizona's Family meteorologist Holly Bock. The National Weather Service Phoenix office and FOX 10 Phoenix are tracking the same pattern.
Storms are expected to fire up Monday evening across eastern and southeastern Arizona. If outflow boundaries push into the Valley, impacts could include blowing dust and the possibility for showers and storms to develop. Any storms that do develop could bring strong wind gusts, blowing dust and heavy rain. A 30% storm chance covers Monday night, with models not showing activity picking up until late.
A flood watch is in effect Monday for southern Arizona, including Tucson. Tuesday, the watch covers southeastern Arizona, now including Cochise County.
Storm chances climb to around 50% for Tuesday and Wednesday night, lingering into Thursday morning. The week also brings a modest temperature break, with highs around 105 degrees Tuesday, 101 Wednesday and 99 degrees Thursday, below normal for this time of year.
By Friday, storm chances are down and temperatures will heat up again.
