What's driving this forecast
The 2026-27 season is simulated by resampling Mt Hood Skibowl's historical seasons weighted toward El Niño analog years. NOAA CPC El Niño Advisory (June 11, 2026): El Niño conditions are present and expected to strengthen into winter 2026-27, with a 63% chance of a very strong event (Niño3.4 ≥ +2.0°C) during Nov-Jan. CPC DJF strength odds: very strong 46%, strong 33%, moderate 16%. IRI (June 22) concurs at 98% El Niño for DJF.
The most reliable ENSO ski signal in the US: La Niña winters run ~115-125% of normal in the Cascades; El Niño is 'the great snowfall suppressor' (NOAA) with warmer storms and higher snow levels. Applied as a -7% tilt at partial weight.
Day-to-day weather models have no skill this far out, so the near-term forecast contributes 0% weight today. The simulation leans entirely on ENSO-conditioned climatology — exactly what an honest seasonal outlook should do in summer. Weighting shifts toward live forecasts as opening day approaches.
The regional readPNW · from the 2026-27 outlook
No US region has more to lose from a strong El Niño: the jet dives south and the Cascades marinate in mild Pacific air. The analogs are grim — 2023-24 delivered one of the worst Cascade seasons in memory with mid-winter rain to the summits, and 1997-98 ran well below normal; 2015-16 was the merciful near-normal exception. Odds strongly favor below-average snowfall and elevated freezing levels, hitting low-elevation terrain hardest. Book March, not December.
