"The Northern Rockies are lined up for a warm-to-cool transition storm cycle from Monday night through Friday, with the most dependable resort snow focused in central Idaho, the Tetons, and parts of the Canadian Rockies before confidence drops sharply this weekend into early next week. Guidance is tightly clustered on storm timing through Friday but shows meaningful spread in snowfall intensity from zone to zone, especially in the Tetons and interior Idaho."
"Snow levels stay relatively high in Idaho and western Wyoming for part of this wave, generally around 5,500 to 7,000 feet with periods where lower-mountain terrain mixes with rain, while farther north they are much lower (roughly 1,500 to 3,500 feet), supporting cleaner all-snow outcomes. Snow quality reflects that split: southern SLRs are mostly around 7:1 to 10:1 (dense to heavy), while northern resorts are more often 12:1 to 16:1 (fair to fluffy)."
A warm-to-cool storm cycle is expected across the Northern Rockies from Monday night through Friday, with the most reliable resort snowfall in central Idaho, the Tetons, and parts of the Canadian Rockies. Models agree on timing through Friday but diverge on intensity across zones. The primary Monday-night–Wednesday wave spreads snow, peaks Tuesday into early Wednesday, and features high snow levels (5,500–7,000 ft) in Idaho and western Wyoming with some rain mixing, while northern areas have much lower snow levels (1,500–3,500 ft) and cleaner all-snow. Snow ratios trend denser in the south (7:1–10:1) and lighter in the north (12:1–16:1). Gusty ridgeline winds (35–55 mph) are likely. Multi-day totals cluster roughly 14″–20″ at favored resorts and about 8″–18″ at strong southern targets, with lower-elevation areas nearer single digits. Confidence drops sharply after Friday into early next week.
