MOST ACCURATE FORECAST: Back-to-back winter storm hitting Arizona this week!

Posted
and last updated

PHOENIX — Back-to-back winter storms are moving into Arizona to start the week.

The first storm dropped temperatures by 20 degrees on Monday and brought rain, hail and snow to parts of our state.

A stronger and colder storm will move in on Tuesday.

It will be another ABC15 Weather Action Day as travel becomes hazardous across parts of our state and winds really pick up!

Rain, wind and thunderstorms may impact your outdoor plans and travel plans across the Valley on Tuesday evening.

Up north, snow-covered roads and reduced visibility from blowing snow will significantly impact travel. Take action now to adjust or cancel your travel plans in the high country on Tuesday.

Wind Advisories and High Wind Warnings are in effect across much of Arizona on Tuesday. Peak gusts could top 40 mph even here in the Valley!

Snow levels will plummet too, falling to near 2,500 feet by late Tuesday night.

We could see an additional tenth to two-tenths of an inch of rain in parts of the Valley as showers and thunderstorms push through Tuesday evening.

We could even see some snow flakes make it down into places like Carefree, Cave Creek, north Scottsdale and Fountain Hills.

Our highest elevations, like Flagstaff, will pick up an additional 8 to 12 inches of snow.

Winter Storm Warnings are in effect across the Arizona high country throughout the day Tuesday and into Wednesday morning.

As the cold air settles in behind the storm, temperatures in the Valley will approach the freezing mark early Thursday morning.

Our forecast will dry out again Wednesday through Friday, but we're already tracking another storm that could bring more rain and snow this weekend.

Stay tuned for updates as we get closer!
