12.21 Snow Before You Go: Active Holiday Jet Stream East & West

Santa delivers an active jet stream for the Intermountain West over the next five days. That keeps the snow falling through Christmas Day with two to three storm systems lined up. In the Northeast, the pattern remains active with two storm systems riding the jet stream—one could target Christmas Day.  

Northeast: With the jet stream just offshore, it opens the door for two storm systems. The first delivers light to moderate snow accumulation at the ski areas Friday-Saturday. Some mixing of the precipitation may occur as warm air fluxes in from the south. The second storm system may arrive in time for Christmas Day with moderate to (in some cases) heavy snow accumulation at the ski areas. This storm system is further out in the forecast period and remains uncertain.  

Colorado, Utah: Storm system number one delivers light to moderate snow accumulation in both states on Thursday. Storm number two delivers light to moderate snow accumulation on Saturday. A third storm system is possible on Christmas Day with light snow accumulation. In Colorado, both storm systems favor the Central and Northern mountain zones for best accumulation. In Utah, the first storm system is not a blockbuster for the Wasatch Front, but the second storm system looks better.     

Wyoming, Montana, Idaho: Snow winds down on Thursday morning and another storm system approaches with moderate snow accumulations (heavy accumulation in the Tetons) Friday-Saturday. A third chance for snow arrives on Christmas Day with light to moderate accumulation. Skiing should be excellent.  

Pacific Northwest: There are two chances for snow in the next five days. The first storm system delivers moderate accumulations (a few heavy pockets as you go south) Friday-Saturday to the high Cascades and volcanoes. The second storm system arrives in time for Christmas Day with moderate snow accumulation. That snow may linger through Tuesday into Wednesday with additional accumulation.  

Whistler/Blackcomb: There are two storm systems lined up over the next five days. The first storm on Friday appears small with light snow accumulation. The second storm system is larger with moderate snow accumulation on Christmas Day and that snow may linger into Tuesday with additional accumulation.  

California: The only chance for snow over the next five days ends Wednesday night into Thursday morning, then it's dry through Christmas.  

Tomer's Take: On Friday, ski in Colorado at Steamboat, Vail or Loveland. On Saturday, ski at Schweitzer, Big Sky or Jackson Hole. On Sunday, ski Alta or Snowbird. On Christmas Day, take a look at the Northeast if the storm system develops.
