Big end to 2021; Forecast into 2022

Tomer’s Take

  • Final storm system merger underway for 2021 in UT, CO, NM, WY.
  • Looking into 2022, the storm track shifts north to favor the Pacific Northwest, British Columbia, Banff area, ID, WY, MT. Plan on major snow accumulation of 25-60″ at Stevens Pass, Baker, Rainier, Whistler/Blackcomb, Timberline, and Bachelor.
  • Then the jet stream shifts a little further south starting on the 4th and brushes northern UT and northern CO.
  • 8-day storm cycle totals now stand at 89″ in Crested Butte and will likely increase to about 105″ by 1/1. Schofield Pass SWE sits at 12.3″ since 12/23. These two pieces of data suggest a top-3 storm cycle for the Crested Butte zone. It rivals March 2019 and the Bury Butte storm cycle of January 2017.

What’s Next?

The jet stream shifts north the first week of 2022 and favors the PNW, B.C., the northern tier of the Rockies, ID, MT, and WY. Starting on the 4th, snow will brush the Wasatch and northern zones of Colorado.

Jet stream forecast valid 1/3-1/4, GFS interpretation.

    This storm has been ALL-TIME‼️ We have been entrenched for days. It’s important to remember Patrol and mountain Ops are working long hours just to get terrain open. A smile, a high five or knuckles and a sincere YEHAW AND THANK YOU goes a long way. Please be patient, be kind and be grateful these humans are working so hard for the pleasure of so many recreationalists ??❄️?‼️
