Another sunny, dry and warm day expected for Christmas Eve.

The above normal temperatures are about to leave for the holidays though. A system is approaching from the Pacific that will bring below normal temperatures, valley rain, and mountain snow for Christmas Day.

Clouds will move in from the west on Tuesday. Chances for showers go up as the day goes on. By evening the cold front will bring showers to southern Arizona. Wettest spots will be east of Tucson between .20" -.40" of rain. We may even hear a few claps of thunder with this system.

Snow levels will drop from 7,000 feet to 5,000 feet with this front. Mountains will get 4 to 7 inches of snow above 7,000 feet and one or two inches from 5,000'-7,000. Areas just below 5,000 feet in elevation will get around a half inch of rain.

That system brings us colder weather for the rest of the week. High temperatures will struggle to get out of the 50s and low temperatures will get near freezing overnight. Thursday should be dry.

We'll be watching for a slight chance of showers Friday night into Saturday. If it times out just right we could get snow flurries close to the valley floor.... stay tuned...

Merry Christmas and Happy New Year!
