When it starts

Best bet this week — Nice day Friday at Grand Targhee: 3.8" by first chair (5pm–8am), 7.8" skiable, snow starts ~12am. 4 days out, so low confidence.

Atwater SNOTEL · 8750 ft · as of 2026-10-17. Pillow, not the resort report.

Nice day

2.8" skiable. First chair 1.1" / on hill 1.6". Nice if you're already going. Not a weekday dare.

Confidence: Low — often a coin flip. Sunday calling Friday. The backtest missed real storms at this range more than it invented them. Don't take the day off on this number.
