SnowSure™ blend — verified model weighting
The black line is not a simple average. For Mammoth Mountain (sierra), we combine seven global weather models using weights learned from daily forecast verification — comparing each model's prediction to measured snowfall (SNOTEL, resort reports, ERA5).
- 1.Horizon buckets: days 1–3, 4–7, and 8–14 each get separate weights — short-range skill differs from long-range.
- 2.Regional calibration: weights come from verified error in this geography (Rockies, Alps, Japan, etc.), recalculated weekly.
- 3.Ground truth only: we never grade a forecast against another model — only against measured snow.

5-Yr Avg by Now
Snowfall over the past five years has been significantly higher than the 30-year average, with the 5-year average exceeding the long-term mean by over 65%. This period includes an extreme anomaly in 2022, when snowfall reached 1,310.9 cm—more than triple the 30-year average—skewing the short-term trend upward. Excluding this outlier, recent seasons have generally remained above the long-term average, though the current season's snowfall is 33% below the recent 5-year average but still 12% above the 30-year norm. This suggests increased variability and occasional extreme snowfall events in recent years.
