MOST ACCURATE FORECAST: Rain and snow showers across Arizona as two storm systems approach our state

Posted
and last updated

PHOENIX — Moisture is streaming into Arizona from a storm system sitting off the coast of southern California.

That's bringing a few rain showers to the Valley today along with a few thunderstorms in southern Arizona.

At the same time, another storm system is moving through the Pacific Northwest and will pass north of our state on Tuesday. That will pick up our winds and bring more chances for spotty showers to our state.

Peak gusts will hit 25 to 30 mph in the Valley.

Up north, Wind Advisories are in effect until 8 p.m. Tuesday along the Mogollon Rim and across all of northeastern Arizona. Gusts in these spots could reach 55 mph.

The storm offshore will finally track through Arizona on Wednesday keeping rain and snow chances going through the middle of the week.

Here in the Valley, rainfall will be minimal with less than a tenth of an inch of rain.

In northern Arizona, snow levels will remain high at 7,000 to 7,500 feet. Snow accumulations in Flagstaff will likely be at less than an inch.

Valley highs will drop back into the mid to upper 70s for most of this week. Overnight lows will cool into the 50s.

We'll dry out Thursday and Friday as we warm up to the low 80s by Friday afternoon.

Then, we're tracking another storm that could bring more wind, rain and snow to Arizona on Sunday. Stay tuned for updates as we get closer.
