MOST ACCURATE FORECAST: MAJOR winter storm hitting Arizona!

Posted
and last updated

PHOENIX — Another powerful winter storm is hitting Arizona!

High winds, thunderstorms and hazardous travel conditions are putting us in ABC15 Weather Action mode.

Up north, snow-covered roads and reduced visibility from blowing snow will significantly impact travel. Travel will be hazardous overnight and numerous roads are closed across the high country.

Our highest elevations, like Flagstaff, will pick up an additional 6 to 12 inches of snow overnight and Wednesday before this storm clears out.

Winter Storm Warnings and Winter Weather Advisories are in effect across the Arizona high country through Wednesday morning.

Here in the Valley, thunderstorms are clearing to the east overnight after bringing heavy rain, lightning, hail and wind gusts near 45 mph.

Sky Harbor picked up 0.13 inches of rain with rainfall totals up to 0.35 inches in some East Valley locations.

As the cold air settles in behind the storm, temperatures in parts of the Valley will approach the freezing mark early Wednesday and Thursday mornings.

Frost is possible, so cover any sensitive plants you have.

Our forecast will dry out again to end the week, but we're already tracking another storm that could bring more rain and snow to our state this weekend.

Stay tuned for updates as we get closer!
