NWS Forecast Accuracy
Accuracy grade pending, and it stays that way on purpose. We show the raw NWS forecast for Grand Targhee 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.
