PHOENIX -- A storm system moving through Utah Saturday will drop a cold front into Arizona. This will bring cold temperatures, gusty winds and a little snow.

Saturday afternoon, Phoenix Sky Harbor reached a high of 77 after a morning low of 57. The seasonal average high for this time of the year is 76. Sunday night, temps around the Phoenix metro are forecast to drop into the mid and low 50s under clear skies.

Early Sunday morning, snow showers are expected to fall across northeastern Arizona, especially across Navajo and Apache counties, where an inch is possible across the lowest elevations. That snow will spread into eastern Arizona, through the White Mountains by mid morning. Flagstaff may see a mix of rain and snow, but little to no accumulation is expected. Travel down Interstate 40 east of Flagstaff Sunday morning may include slick roadways and reduced visibilities.

Winds will increase mid morning across all of Arizona, but especially in the high country where wind gusts in excess of 30 miles per hour could produce wind chills in the 20s.

The rain and snow is expected to taper off late morning.

In the Valley, expect sunny skies and locally breezy winds Sunday with a high of around 72 in Phoenix.

Overnight low temperatures will fall to their coldest levels so far this season. In the Phoenix metro, forecast lows will dip into the 40s Monday morning through at least Wednesday morning. Daytime highs will be cooler than average, reaching the low 70s.
