The storm track will keep the best snow in the Rockies between Thursday and Monday.    

Colorado, Utah, New Mexico: Excellent conditions. New snow arrives on Thursday night, Friday and continues on Saturday. Moderate to heavy accumulations in the Central and Northern Mountains of Colorado. Light to moderate accumulations in the Southern Mountains. In New Mexico, light accumulations. In Utah, light to moderate accumulations in the Wasatch from Thursday evening through Friday.

Wyoming, Montana, Idaho: Excellent conditions. New snow arrives on Thursday evening and continues on Friday. Moderate to heavy accumulations. Leftover light snows on Saturday morning. A second storm system with snow arrives on Sunday afternoon continuing into Monday with moderate to heavy snow accumulations.  

Northeast: A storm system on Friday looks rather warm with mostly rain but some snow in Northern VT, NH and ME. A second storm on Sunday night and Monday also looks warm with more rain than snow at least initially. Snow develops on the backside as colder air moves in.  

California: A rather benign stretch with the only chance of meaningful snow arriving Sunday night into Monday and it looks light.   

PNW: A storm system rolls through on Thursday and ends Friday morning. A second storm system arrives Saturday evening continuing on Sunday.   

Tomer's Take: Ski Jackson Hole on Friday for new powder, Winter Park or Loveland on Saturday for new powder, and Big Sky or Whitefish on Sunday. Honorable mention goes to Sun Valley on Monday for new powder.
