WED JAN 29 2014

A strong westerly flow (a group of storms) continues to weaken our persistent West Coast Ridge. This and moisture extending back to Hawaii (evident on Satellite imagery) has created the likelihood of valley rain and mountain snow Wednesday night through Thursday night. Snow levels should run in the 7,000 foot range in that time period. Snow amounts could be as high as a foot or more at the Crest level. For the weekend and into early next week, a troughy pattern continues off the West Coast, with the big ridge now pushed well out over the Pacific (about 135W).
