SnowSure™ blend — verified model weighting

The black line is not a simple average. For Mt. Rose (sierra), 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.

El Niño Outlook · Winter 2026-27

Mt. Rose El Niño rank & forecast

Mt. Rose ranks #68 of 488 SnowSure resorts — Tier A, +10% in strong El Niño winters.

Tier A — Prime El Niño terrain: Historically snowed much more than normal in strong El Niño winters (≥ +8% vs this resort’s own 30-year average).

#68 of 488Tier A — Prime El Niño terrain

Strong-event signal: +10% vs this resort's 30-yr avg

In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Mt. Rose averaged +10% 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, Mt. Rose sits on the favorable side of the ledger. Analog winters: '97-98 +28%, '15-16 -2%, '23-24 +5%. A pattern, not a promise.

'97-98 +28%'15-16 −2%'23-24 +5%

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.

Key

What the tiers mean

% vs each resort's own 30-year average in strong El Niño winters.

Tier	Signal	Means
A — Prime terrain	≥ +8%	Historically much snowier than normal.
B — Favored	+3% to +8%	Modest upside vs normal.
C — ENSO-proof	about −3% to +3%	Near-normal snowfall — a hedge, not a jackpot or bust.
D — Late bloomer	−3% to −8%	Often lighter early — aim Feb–Mar.
E — Timing play	≤ −8%	Often lighter overall — aim late winter.
