This weekend will be remembered for a change in the storm track delivering heavy snow back to California, including Tahoe south to Mammoth. But, some of it will start as rain. Out East, there are two chances for light snow, but overall the storm track will not favor heavy snow this weekend. 

California: After a dry, mild stretch the pattern will change this weekend with heavy rain and snow on the way. There are two different storm systems. The first looks quite warm with more rain than snow between Friday and Saturday. As time goes on the rain shifts more towards snow at Tahoe and south to Mammoth. Mammoth looks most reliable for snow during this first storm. The second storm Sunday through Monday is mostly heavy snow at the ski areas. Accumulations: The first storm system delivers light to moderate snow with rain, while the second storm system delivers as much as 50 inches of snow between Tahoe and Mammoth. Valley flooding is likely. 

Northeast: Light snow brushes southern New England and the Great Lakes between Thursday night, Friday and Saturday morning. Not everyone will see this snow. Potential exists for a nor’easter between Friday evening and Saturday morning with heavier snow near the coast depending on the exact track. If the storm stays off the coast then the ski areas get missed entirely. An Alberta Clipper drops in on Monday with light to moderate snow for Vermont, New Hampshire and Maine.

Colorado, Utah and New Mexico: Low snow chances until the main storm system arrives Sunday evening through Tuesday. One exception will be a small batch of snow that sweeps through Southern Utah and Southern and Central Colorado between Saturday afternoon and Sunday morning with light snow accumulations. Moderate to heavy snow accumulations in Utah's Wasatch between Sunday evening and Tuesday morning. In Colorado, moderate to heavy snow accumulations between Sunday evening and Tuesday morning. In New Mexico, moderate snow accumulations between Sunday evening and Tuesday morning. 

Wyoming, Montana and Idaho: A small wave of light rain/snow brushes the ski areas between Thursday evening and Friday morning. Initially snow levels may be running high with rain/snow at some of the base areas, changing to snow later. Then, a much larger storm system with moderate to heavy snow accumulations arriving Sunday morning and continuing through Tuesday.     

Tomer's Take: Ski Jackson Hole on Friday, Mammoth on Saturday and Heavenly or Northstar on Sunday. Bonus: Ski Kirkwood or Snowmass on Monday.
