Black line = verified SnowSure™ blend (not a simple average). Weights update weekly from measured snowfall at SNOTEL stations and resort reports.
SnowSure™ blend — verified model weighting
The black line is not a simple average. For Buttermilk Mountain (rockies), 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
Over the past five years, average seasonal snowfall has exceeded the 30-year average by approximately 10%, indicating a recent upward trend. However, the current season's snowfall is significantly below both the 5-year and 30-year averages, at just 71% and 78% of those benchmarks, respectively. This marks a notable anomaly following several years of above-average snowfall, suggesting increased variability and a sharp decline in the most recent season.
