A unseasonable winter storm system is headed for the Western United States and most mountainous areas west of the continental divide should see significant snowfall by Friday afternoon reports NOAA.
Current models show the storm hitting Oregon and California hard on Tuesday (*Timberline, Mt Bachelor, Squaw, Mt Rose, and Mammoth are all still open) before pausing on the Wasatch and dumping over a FOOT of snow on Snowbird by Thursday morning. Snowfall will also hit the Tetons and Wind River Range in Wyoming, Absaroka Mountains in Montana, and parts of central and eastern Idaho before moving over northern Colorado and into the front range.
“Cool, late season Pacific weather systems will bring snow to unseasonable levels. Up to a foot of snow is possible above 5000 feet in the Cascades.” – NWS
Expect A-Basin to pick up some new snow which we expect will result in a short extension of their season… Fingers crossed. As of today, A-Basin is scheduled to close on 6/4.
Snow levels will vary largely depending on northern orientation. Models have snow levels in parts of Montana dropping to 4,000′ whereas the Wasatch will see snow levels closer to 5,500′. Snow levels in Colorado and California will be even higher.

NOAA Forecast Discussion
Much of the northern-tier will be in an active wet pattern as a couple of lows rotate through the the upper-level trough moving through the West. Rain and higher elevation snow will spread across parts of the Pacific Northwest and northern California eastward into parts of the Northern Rockies as an approaching frontal system tracks across the Pacific Northwest/ Intermountain West. Portions of the Cascades could have periods of heavy precipitation during this time.
