2025-26 is Incomplete at this official gauge (63 missing days). Observed snowfall is 77.4 in, counting gaps as zero — a lower bound, not a confirmed quiet year.
Official gauges only (NOAA GHCN-Daily snowfall and NRCS SNOTEL winter precipitation). Not resort marketing, not OpenSnow, not OnTheSnow. This page uses the NOAA GHCN-Daily station USC00437612. Mid-mountain ESTIMATE inches, when shown, are labeled estimates — not a resort report. This gauge sits in the valley or village, not on the summit.
Gappy seasons are excluded from the historical sample. We do not paint the zero-filled total as a poor / quiet percentile on the map.

ESTIMATE: ski-area coordinate ÷ official gauge, OSU PRISM 4 km 1991–2020 November–April precipitation normals. Applied to this season’s observed gauge snowfall. Precipitation, not fluff inches, and 4 km cells smooth the Green Mountains — labeled estimate only, not a resort snowfall report.
This estimate multiplies the incomplete observed total. Missing days are still zero — treat both numbers as a lower bound.
Vermont official gauges sit in villages and valleys, often 500–2,000+ ft below mid-mountain. The percentile compares this gauge to its own past — it is not an on-mountain snow report. This gauge is 1,159 ft below the ~2,500 ft mid-mountain used for the estimate.
Cumulative observed snowfall
Ghost lines are past seasons. Dashed is the median. Band is the 10th–90th percentile envelope. X-axis is day of season, not calendar year.
Sliding the date recomputes the percentile against the same calendar date in past seasons — never a full year vs a partial year.
The station
NOAA COOP in South Lincoln — the same Mad River valley gauge already used for Sugarbush. Shared on purpose. 2025-26 is gappy (63 missing days); nearby Warren CoCoRaHS are worse. Treat the percentile as incomplete.
