MOST ACCURATE FORECAST: ABC15 Weather Action Days as a series of winter storms move into Arizona this week

Posted
and last updated

PHOENIX — A series of winter storms will impact Arizona this week bringing Valley rain, high country snow, gusty winds and big dose of cool air.

This wet weather will impact travel and outdoor activities, including the Phoenix Open. So, Tuesday, Wednesday, Thursday and Friday will all be ABC15 Weather Action Days.

Take action to get ready for a stormy week and make sure your vehicle is prepared for winter driving conditions in the high country.

The first round of wind, rain and snow hits now through Wednesday. Then, we'll see another round of rain and snow on Thursday and a third round on Friday as two more winter storms move through.

We could also see thunderstorms in the mix, which could bring heavier downpours at times.

Throughout the week, we could pick up a half an inch to an inch and a half of rain across our Valley neighborhoods.

That will likely lead to longer than normal commutes, ponding water on the roads and areas of flooding.

Flood Watches are now in effect through Wednesday evening for parts of central and western Arizona, including the Valley. Do not attempt to drive through flooded washes or roadways. "Turn Around, Don't Drown".

Winter Storm Warnings are in effect through Wednesday night for areas above 6,000 feet in elevation in Yavapai County, along the Mogollon Rim and in the White Mountains.

Snow levels will drop to around 6,500 feet tonight before falling to around 5,000 feet by Wednesday night.

Places like Flagstaff, Williams, and Forest Lakes could end up with nearly a foot of snow from this first storm and another foot of snow Thursday through Saturday.

Road conditions will deteriorate rapidly across the high country. Watch out for slick, snow-covered roads and areas of blowing snow and low visibility.

If you're headed to any Phoenix Open events, be prepared for rain and thunderstorms which may cause delays or require you to seek shelter.

It's also getting much cooler as these storms move in. Look for Valley highs in the upper 60s today and upper 50s to low 60s for the rest of the week.

Early morning lows will be in the 40s Valley-wide by Thursday morning.
