MOST ACCURATE FORECAST: Winter storm bringing rain and snow to Arizona

Posted
and last updated

PHOENIX — Rain and snow are falling across Arizona as a winter storm moves through!

Parts of the northwest Valley have already picked up over a two-tenths of an inch of rain and chances for more are in the forecast through Wednesday.

In fact, our best chances for rain in the Valley will be Wednesday morning and we may even see a few thunderstorms in the mix.

So far, no measurable rain has fallen in Phoenix, but there's still time to break this dry streak before it sets a new record.

As of Tuesday, January 28, Phoenix has had 159 days in a row without measurable rain at Sky Harbor marking the second-longest dry streak on record.

If no measurable rain falls at Sky Harbor by Wednesday, Phoenix could tie the all-time record of 160 dry days in a row set in 1972. Then, we may continue to set a new record dry streak each day until rain finally arrives.

Up north, we're tracking the potential of another three to four inches of snow in Flagstaff and another one to two inches of snow in Prescott, Payson, Heber and Show Low by Wednesday evening.

Winds will be breezy at times, but gusts will mainly stay below 25 to 30 mph across the state.

The colder air moving in is dropping Valley temperatures down into the upper 50s to low 60s. Overnight lows are getting colder too, but we are not expecting any freezes in the Valley.

This storm will clear out on Thursday and high pressure will gradually build back in. That will send Valley temperatures up into the 70s over the weekend and potentially into the low to mid 80s early next week.
