MOST ACCURATE FORECAST: Big warm-up ahead of back-to-back storms

Posted
and last updated

PHOENIX — High pressure is building in and bringing the warmest temperatures of the year so far.

Valley highs will reach the low 70s Thursday afternoon and then we'll climb into the mid 70s on Friday.

After that, back-to-back storms are headed our way over the weekend and early next week.

The first storm starts to move in from the west late Saturday bringing more rain, snow and cooler air to our state.

Expect scattered showers and even a few thunderstorms throughout the day on Sunday with a quarter to a half of an inch of rain possible across the Valley.

Up north, snow levels could go as low as 5,000 feet and early estimates show three to six inches of snow possible in Flagstaff.

Another storm will be moving in right behind it late Monday and Tuesday, so rain and snow chances will continue across our state into early next week. Stay tuned for updates on how much more rain and snow we could get in the days ahead.
