SnowSure™ blend — verified model weighting

The black line is not a simple average. For Sipapu (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.

#44 of 488Tier A — Prime El Niño terrain

Strong-event signal: +13% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Sipapu averaged +13% versus its own 30-year snowfall baseline. The pattern has historically been a friend here. With a record-strength event forecast for winter 2026-27, Sipapu sits on the favorable side of the ledger. Analog winters: '97-98 +11%, '15-16 +13%, '23-24 +14%. A pattern, not a promise.

Signal = average snowfall in the three strongest El Niño winters since 1996 ('97-98, '15-16, '23-24) vs this resort's own 30-year ERA5 baseline. n=3 — a lean, not a law. Updated monthly against measured snowfall Dec–Mar.
