A sprawling winter storm delivers new snow to the West in the days leading up to Thanksgiving and for some on Thanksgiving Day. The heaviest snow accumulations should fall in California, and the snow might actually start rather light in Colorado's Central and Northern Mountains before picking up in intensity in the Southern Mountains over the weekend. It looks pretty calm and turning warmer across the Northeast with only small chances for light snow. 

Pacific Northwest: The best snow hits Monday-Tuesday of this week then it turns drier for Thanksgiving. 

California: The best chance for moderate to heavy snowfall is on Tuesday-Wednesday. Then it turns drier on Thanksgiving with some light snows returning on Black Friday. Tahoe, Kirkwood and Mammoth should all do well with at least 6" if not much more total accumulation this week.  

West: The best snow falls in Idaho and Montana late Monday through Tuesday with moderate accumulations. Same story in Wyoming late Tuesday through Wednesday. Utah gets hit Wednesday afternoon through Thanksgiving, also with moderate accumulations.

The best snow hits Colorado starting Wednesday evening and continuing on Thanksgiving. At this point, we're not talking blockbuster snow in Colorado. Accumulations may start light in the Central and Northern Mountains before picking up in intensity over the weekend in the Southern Mountains.   

Northeast: Light snow is possible from Thanksgiving through Saturday, but the chances are low. Otherwise rather dry conditions and turning warmer.   

Tomer's Take: Ski Kirkwood or Mammoth on Wednesday, Alta or Vail on Thanksgiving, and Steamboat on Friday.
