The black line is not a simple average. For Whitetail (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).

El Niño Outlook · Winter 2026-27
Whitetail is under review in SnowSure's El Niño dataset — we will not publish a rank against a discontinuous historical series.
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.
In 10 past El Niño winters at Whitetail, ERA5 season snowfall median was 71 cm (28 in), about 41% above this resort’s long-term median. This is a historical analog from reanalysis — not a prediction of this winter’s storm track.
