A stronger push of moisture will bring a better chance for a few rain and snow showers Friday area wide.  Highs in the 30s. 

An even strong push of mild and moist air will bring a good chance of valley rain and high mountain snow Saturday night through Monday.  Snow levels will rise, but not before several inches fall in the higher elevations.
