Powder Christmas for many; Major storm cycle

Tomer’s Take

  • Major storm cycle through 12/31 with 4-5 different storm systems rotating through California into UT, ID, MT, WY, and CO.
  • Grand totals will be in feet.
  • Major avalanche cycle in the backcountry if this verifies.

Look at the size of the trough developing off the West Coast. It’s huge and will run 3+ standard deviations from the 30 year average. Energy will rotate through the trough and then into CA and the Interior West.

Look at the storm track through Christmas. Perfect formation for big Western snow.
