Posted
and last updated

PHOENIX — Finally, a winter storm is headed to Arizona!

Winds will pick up, rain and snow will move in, and temperatures will drop significantly across our state.

Phoenix will drop into the 60s starting Tuesday and continue to cool through the middle of the week.

There's a slight chance of a few spotty showers in the Valley too, mainly Tuesday evening through Wednesday morning. Some spots could pick up around a tenth of an inch of rain.

Up north, the snow level will gradually fall to around 3,500 feet. Flagstaff could get one to three inches with six to eight inches possible over the San Francisco Peaks.

Generally totals up up to two inches of snow are expected along the Mogollon Rim. High winds will lead to blowing snow and low visibility, so travel is not recommended Tuesday night into early Wednesday morning.

By Wednesday afternoon and evening, snow showers will spread into southeastern Arizona with the highest peaks potentially getting six to ten inches of fresh snow.

Out west, is more about the wind than the rain or snow.

A High Wind Warning is in effect for the Colorado River Valley from Tuesday morning through Wednesday afternoon. Gusts there could reach up to 60 mph. So, if you’re traveling in western Arizona, particularly in high-profile vehicles, consider postponing plans.

Wind Advisories are also in effect for parts of western Arizona, including Mohave County and portions of the Parker Valley Tuesday and Wednesday with gusts up to 50 mph possible.

Behind the storm, cooler air will continue to flow in.

Daytime highs will drop into the low to mid 60s in the Valley Wednesday through Friday with morning lows in the upper 30s to low 40s by Thursday morning. Some outlying areas may even experience freezing overnight temperatures later in the week.

Freeze Watches are in effect Wednesday night into Thursday morning and again Thursday night into Friday morning across southeastern Arizona, this includes parts of Pinal County like Eloy and Arizona City. So, remember to cover any exposed pipes and sensitive plants before those freezing temperatures hit.
