Storm on the way to Arizona with First Alert Days declared

PHOENIX (AZFamily) — Big weather changes are on the way for Arizona during the second half of this week, with First Alert Weather Days issued for Friday and Saturday.

High pressure over the region will continue to bring warm and dry conditions today and tomorrow, but clouds will begin to increase ahead of a weather pattern change that arrives Friday. Look for mostly cloudy skies in the Valley today with a forecast high of 72 degrees. We’ll top out near 74 degrees with more cloud cover expected tomorrow.

On Friday, an area of low pressure is forecast to move into Arizona, bringing rain to the Valley. Rain chances are near 20% during the day Friday and jump to 50% Friday night. While light rain is possible Friday afternoon, more measurable and widespread rain is expected Friday night and into Saturday morning.

Saturday could also bring a few thunderstorms, with small hail possible. Afternoon temperatures will peak in the low 70s on Friday and upper 60s on Saturday. Rain chances are near 50% Saturday during the day and near 20% for Saturday night. Sunday looks dry in the Valley but cool with highs in the mid 60s.

In the high country, travel could be tricky Friday and Saturday with reduced visibility from rain and snow. Snow levels will start fairly high near 6,500 to 7,000 feet on Friday, but will eventually fall a bit. One or two inches of snow is likely for Flagstaff on Friday and Saturday, with 2 to 6 inches likely on the Mogollon Rim. In the White Mountains, more snow is expected with 8 inches or more above 8,000 feet.
