PHOENIX (AZFamily) — It’s a First Alert Weather Day as showers and thunderstorms move through Arizona today. Saturday and Sunday are also First Alert Weather Days with active weather expected for the weekend ahead.

Moisture associated with Tropical Storm Priscilla is pushing up into Arizona. A trough of low pressure off the West Coast is helping to add instability, leading to additional thunderstorm chances today and tomorrow.

In the Valley, look for a chance of showers and thunderstorms throughout the day. Heavier and more widespread showers and storms are likely by late this afternoon and into the evening.

Rainfall totals are expected to be over an inch for much of the Valley, with more than two inches possible in the higher elevations on the northern and eastern edges of the Valley.
