SnowSure™ blend — verified model weighting

The black line is not a simple average. For Mt Mawson (southern alps), 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.

Mt Mawson El Niño rank & forecast

Mt Mawson is under review in SnowSure's El Niño dataset — we will not publish a rank against a discontinuous historical series.

Under review

This station is under review and carries no rank: its 30-year ERA5 baseline falls below the 80cm floor our methodology commits to, so percentage swings computed on it are unstable by construction. We expect it to benefit from El Niño; our method cannot size that reliably.

History · not a forecast

In 6 past El Niño winters at Mt Mawson, ERA5 season snowfall median was 42 cm (17 in), about 2% below this resort’s long-term median. This is a historical analog from reanalysis — not a prediction of this winter’s storm track.
