MOST ACCURATE FORECAST: More rain and snow to end 2021!

Posted at 4:38 AM, Dec 28, 2021

PHOENIX — Back-to-back winter storms will bring rain, snow and cooler air to Arizona as we wrap up 2021.

Rain and snow showers will last into the late night hours as the first winter storm moves in.

Winter Weather Advisories are in effect across the high country, mainly in areas above 4,500 feet in elevation.

Snowfall totals will be in the 4 to 12 inch range above 5,500 feet in elevation.

Flagstaff could pick up 6 to 10 inches of snow and we could see 4 to 8 inches in places like Prescott, Payson, Heber and Show Low.

In the Valley, expect rain showers to gradually taper off through the overnight hours.

Rainfall totals across the Valley will range from a trace to a quarter of an inch.

There's a chance of a few more spotty showers Wednesday, then the next big winter storm arrives by New Year's Eve.

Expect more rain and maybe even a few thunderstorms in the mix Thursday and Friday.

Early estimates show the potential of a half an inch to an inch of rain in the Valley and a lot more snow up north. So, stay tuned for more details as we get closer.

In the meantime, plan on a wet and chilly New Year's Eve. Temperatures at midnight will be in the upper 40s to low 50s across the Valley.
