SnowSure™ blend — verified model weighting
The black line is not a simple average. For Las Leñas (andes), 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
Recent snowfall has been highly variable, with the past five years showing significant fluctuations between low and high snowfall seasons. The current season's snowfall is 175% above the 5-year average and 238% above the 30-year average, indicating an exceptional anomaly compared to both short- and long-term trends. While the 5-year average is already higher than the 30-year average, suggesting a possible upward trend, the current season stands out as an outlier well above historical norms. This recent spike may skew short-term averages and should be monitored for persistence in future seasons.
