PHOENIX — A very unsettled weather pattern sets up shop over the desert southwest for the rest of the week.
A cold, windy and wet storm system will move through Arizona, giving us a chance for rain and snow almost every day.

The next storm system to impact Arizona rolls in late tonight through Sunday evening.
We can expect off and on scattered showers and light snow in the high country.

Rain wise about a trace to .25" of rain in the Valley and .25" - .50" in the high country.

Snow wise about 3-6" above 6,500 feet but snow levels could drop as low as 5,000 feet with just a dusting of snow.

A Winter Weather Advisory for has been issued for the Flagstaff area including Western Mogollon Rim and Kaibab Plateau until 11 pm Sunday night. For areas above 6500 feet the snow mixed with strong winds will lead to dangerous travel conditions.

For the start of the week, more rain and snow. We are tracking another storm system to drop into Arizona late Monday and last through Wednesday morning.
