"The Northern Rockies trend from windy and mostly dry conditions into a more productive midweek snow cycle, with the best in-window snowfall focused on the Tetons and southwest Montana. Friday and Saturday stay mild with strong west winds, then a weak wave brings limited Sunday and Monday snowfall at higher elevations before a brief Tuesday lull."
"Sunday into Monday, guidance is aligned on timing and high snow levels near 6,500-8,000 feet, but diverges on intensity, especially in the Tetons, where accumulations are more likely than elsewhere. Most areas should stay around 0″-2″, while the Tetons are better positioned for 3″-8″. Snow quality in this first wave looks dense, with SLRs mostly around 8-10."
"A colder front arrives Wednesday and Thursday, snow levels fall from around 6,500-8,000 feet to near 3,500-5,000 feet by Thursday night, and conditions turn more winter-like for many upper-mountain zones. Wind impacts look moderate rather than extreme during this phase, with many mountain locations gusting around 25-35 mph."
The Northern Rockies will transition from windy, mostly dry conditions into a significant midweek snow cycle. Friday and Saturday remain mild with strong west winds gusting 25-40 mph, followed by weak Sunday and Monday snowfall at higher elevations with snow levels near 6,500-8,000 feet. Most areas will receive 0-2 inches, while the Tetons are positioned for 3-8 inches with dense snow quality around 8-10 snow-to-liquid ratios. A colder front arrives Wednesday and Thursday, the main storm period, with snow levels dropping to 3,500-5,000 feet by Thursday night. Moderate wind impacts of 25-35 mph are expected during this phase, with improving snow quality as colder air moves in. Forecast confidence is highest through Friday afternoon, then decreases for the following weekend.
