MOST ACCURATE FORECAST: Back-to-back storms impacting Arizona this week

Posted
and last updated

PHOENIX — We're tracking back-to-back storms impacting Arizona this week.

This first one picked up winds across our state on Tuesday afternoon and brought quite a bit of dust into the Valley.

Winds will gradually die down overnight as temperatures drop into the 40s.

As cooler air settles in, Valley temperatures will drop into the mid 60s Wednesday afternoon putting us a few degrees below normal for this time of year.

More clouds move in on Wednesday too ahead of the next storm system brewing off the coast of California. There's even a slight chance we could see a few light, spotty showers in the Valley by Wednesday evening.

The main impacts from this storm will hit on Thursday and Friday as rain and snow showers fall across our state.

It will be a warmer storm, so snow levels will be hovering between 6,000 and 7,000 feet.

Early estimates show the possibility of around two to five inches of snow in Flagstaff and along parts of the Mogollon Rim.

Here in the Valley, we'll see chances for showers and thunderstorms with the majority of the activity happening late Thursday night and Friday. The rain showers will likely be hit or miss, so some Valley spots may see nothing while others potentially see up to a quarter of an inch of rain.

We are still a few days out from this storm's impacts, so stay tuned for updates as we get closer.
