NWS Forecast Accuracy
Accuracy grade pending, and it stays that way on purpose. We show the raw NWS forecast for Big Sky and do not grade or correct it. Six winters of NWS-against-SNOTEL checking found forecast accuracy here turns on an unresolved snow-measurement question (settled snow depth vs. fresh snowfall), not a fixed per-mountain bias anyone can honestly correct. So we show the number NWS publishes and tell you that is what it is.

Local Knowledge
TGR Community IntelStorm Day Strategy
On high wind days (gusts 80+ mph), focus on walk-on tram runs with wind-buffed smooth conditions rather than attempting upper mountain access. Wind-groomed terrain offers carving comparable to powder days with no crowds. On fresh snow days, monitor donut hole patterns—Big Sky historically receives scattered snow amid regional storms; be ready to capitalize when snow finally arrives. Spring season strategy: prioritize skiing early in morning before melt accelerates.
