TUCSON, AZ (KOLD) - Technically it's still fall for another two weeks, but a storm system moving into Arizona will make it feel and look like winter in some areas.
Southern Arizona is on the warm side of the storm so most people will experience only rain. Snow levels only drop to about 6000' by Tuesday morning with some rain/snow mix as low as 5000'.
Most people in southern Arizona live and travel below 6000'.
Showers begin today with increasing coverage after sunset. The biggest push of rain for southern Arizona will be overnight with heavy rain, thunder, and lightning possible during the early morning hours of Tuesday as a cold front moves through. Rain and snow taper off through the morning Tuesday with afternoon sunshine and a few leftover clouds and showers, mostly southeast of Tucson.
A Winter Storm Warning is in effect for eastern Pima, Santa Cruz, Cochise, Graham, and Greenlee counties above 6000' from 5 PM this evening to noon on Tuesday. 6" to 12" inches are possible from 6000' to 7000'. 12" to 18" 7000' and above.
In Graham and Greenlee counties a Blizzard Warning is in effect for the same time period above 8000'.
Winds will be gusty with this storm system. The breeze will pick up in southern Arizona this afternoon and peak overnight with 30 MPH winds and wind gusts 45 to 55 MPH. Where it is snowing, white out conditions are possible. Blowing dust could hamper travel at lower elevations today, until the rain begins. Blowing rain could also reduce visibility for travel overnight.
Since this is a wave of tropical moisture and southern Arizona is south of the cold pool of air, temperatures will be mild with the storm. 40s and 50s for lower elevations of southern Arizona the next few days.
