PHOENIX -- An arctic blast of winter is moving into Arizona, just in time for the weekend. 

A winter storm and cold front moved through the state last night and this morning, bringing light rain and snow.  The high country ended up with a couple of inches of snow, with Arizona Snowbowl receiving 7 new inches of powder.  Some spots in the Valley saw a few one-hundredths of an inch of rain.  Sky Harbor got 0.01 inch, which was our first measurable rain of 2013. 

Behind the cold front, a polar air mass is plunging down from Canada.  Although sunny skies will be the rule across Arizona today, highs will struggle to reach 50 degrees in the Phoenix area, and the 20s and low 30s in the high country. 

Overnight lows will bottom out near zero in the high country and in the upper 20s for most parts of the Valley both Saturday and Sunday mornings.  There is a Freeze Warning for the Valley beginning at midnight tonight, and sub-freezing morning temperatures are expected through Tuesday morning. 

Those cold overnight temperatures are expected to help contribute to a temperature inversion, which will help trap pollutants and lead to a stagnant air mass. 

There is a High Pollution Advisory for Maricopa County, which means it's also a No Burn Day.  That advisory is likely to be continued into tomorrow and possibly Sunday as well.
