“Storm system 10/16-10/19 with snow for the mountains of PNW/MT/UT/ID/WY/CO. Precipitation might trickle into 10/20 across the Four Corners. This storm system opens the door for an active pattern 10/21-10/23.”
Summary
A major shift in the weather pattern is set to bring the first significant snowfall of the season to many Western mountain resorts this week.
Pacific Northwest Kicks Off the Action
The storm system is already delivering snow to parts of British Columbia, with Whistler Blackcomb reporting snowfall above 6,000 feet. While it’s still rain at the base, the upper mountain is seeing a nice accumulation.
Inner Mountain West: Snow on the Way
Key Points:
- A storm system moves into the Inner Mountain West between October 16-19
- Snowfall is expected in Utah, Wyoming, Montana, Idaho, and Colorado
- Snow levels will lower as the storm progresses
Snowfall Projections (October 16-20):
- Colorado: Several inches possible, particularly in the northern mountains
- Utah: 5-6 inches from Brian Head to the Wasatch Range
- Wyoming: 5-6 inches for Jackson Hole and Grand Targhee
- Montana: Big Sky could see significant accumulation
- Pacific Northwest: Whistler and Mt. Baker may receive several inches
Extended Outlook: Pattern Shift Favors More Snow
This storm opens the door for an active pattern through late October. Resorts like Jackson Hole and Yellowstone show increased chances for snow accumulation right through the end of the month.
Snowmaking Opportunities
The colder air moving in should allow resorts like Loveland, A-Basin, and Keystone in Colorado to begin snowmaking operations.
