"A long, windy storm cycle will shape the Northern Rockies from Wednesday through Saturday night, with the deepest snow focused on northwest Montana, the Idaho Panhandle, and central Idaho while southwest Idaho stays mostly windy and marginal for accumulation. Confidence is best from Wednesday morning through Saturday night, when guidance is aligned on repeated precipitation, a major wind spike Thursday, and a colder reset late Saturday."
"Wednesday through Thursday night is the most locked-in part of the forecast, and guidance is closely converged on strong west to northwest wind plus steady snowfall from Whitefish and Schweitzer south into Brundage. Exposed terrain will be rough, with many resorts seeing gusts in the 50-70 mph range and locally higher ridge gusts around Whitefish, Schweitzer, Bridger Bowl, Big Sky, Grand Targhee, and Jackson Hole."
"Snow levels also show good agreement on the broad pattern: mostly near valley floors to 5,000 feet in northwest Montana and the Idaho Panhandle, around 5,300-6,600 feet in central Idaho, and closer to 6,000-7,500 feet in western Wyoming and southwest Montana during the warmest part of the event. That keeps Whitefish and Schweitzer in consistently productive snow, gives Brundage the steadiest Idaho refresh, and leaves Sun Valley and Bogus Basin mostly dealing with wind and only spotty light snow."
A significant winter storm system will affect the Northern Rockies from Wednesday through Saturday night, bringing sustained precipitation and strong winds. Northwest Montana, the Idaho Panhandle, and central Idaho will experience the heaviest snow accumulation, while southwest Idaho will remain primarily windy with marginal snow totals. Wind gusts will peak Thursday, reaching 50-70 mph at most resorts with locally higher gusts at exposed ridges. Snow levels will range from valley floors to 5,000 feet in the north, 5,300-6,600 feet in central Idaho, and 6,000-7,500 feet in western Wyoming. Snow quality will be dense to moderate with snow-to-liquid ratios around 8:1 to 12:1. Confidence is highest Wednesday through Saturday night, with some forecast divergence expected Friday into Saturday regarding intensity and timing of colder air arrival.
