Daily Snow Forecasts

Western US
Strong storm to impact the Northwest this weekend
Updated 1 day ago Alan Smith
The next couple of days will remain quiet across the West. Attention then turns to a powerful storm system that will bring heavy rain and high elevation snow to the Pacific Northwest over the weekend. Shower activity should eventually reach the Central Rockies by late in the weekend as well.
US and Canada
Final Forecast for 2020-2021
Updated 4 months ago Alan Smith
An active pattern across the Rockies continues to deliver late-season snow to the remaining ski areas that are open in Colorado. Later this week, a storm will bring high elevation snow to the Pacific Northwest and Canadian Rockies, and over the weekend, portions of the Northern U.S. Rockies (especially Montana) could see heavy snow.
Mammoth
Drier & Warmer...
Updated 4 months ago Bryan Allegretto
