SnowSure™ blend — verified model weighting
The black line is not a simple average. For Blacktail Mountain Ski Area (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.
