NWS Forecast Accuracy
Accuracy grade pending, and it stays that way on purpose. We show the raw NWS forecast for Sierra-at-Tahoe 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.
