Cloudy skies, showers, thunderstorms, breezy winds and cooler temperatures are invading Arizona Sunday as a storm system tracks just south of the state.

This area of low pressure is moving from the Southern California area and tracking westbound across northern Mexico through Monday morning. Southerly flow ahead of it is pumping moisture into Arizona.

In Metro Phoenix, shower chances are at 40 percent Sunday, with the best chances Sunday evening. Some instability is present, there's also a slight chance of thunderstorms during the afternoon and evening hours. Daytime highs will be in the mid-70s.

The low-pressure system will track northeastward into New Mexico Monday, and wrap around moisture will keep rain chances in the Valley forecast at 20 percent.

A shortwave will also rotate along the backside of this low Tuesday, so in response, we'll keep a slight chance of showers in the forecast for Tuesday. Otherwise, look for partly cloudy to mostly sunny skies. Highs will be right around 70 degrees Monday and the low 70s Tuesday.

Rainfall totals for most Valley locations look to be below a tenth of an inch between Sunday and early Tuesday morning.

In the high country, snow levels will remain high with this storm, mainly down to 8,000 feet. Several inches of snow are possible in the higher elevations of east-central Arizona, and right around the Arizona-Utah border through Monday.

Some light snow will fall in areas like Window Rock and Greer. Heavier  accumulation is possible for the very highest elevations of the White Mountains. 

Drying and warming is in the forecast Wednesday and Thursday before another round of stormy weather moves in next weekend. Stay tuned!
