Current signal
El Niño usually tilts the Pacific Northwest warmer in winter. The current 2026–27 CPC outlook strongly favors warmth across the northern tier, while the precipitation signal is less clean along the immediate coast than the classic “El Niño = dry Northwest” shorthand suggests.
What this means for snow
Historically, El Niño suppresses snowfall across much of the Pacific Northwest, especially at lower elevations. High-elevation storms can still deliver major snow, but a warmer background raises rain-line risk.
Travel planning
Expect a higher chance of mild lowland stretches, but mountain passes can still see high-impact storms. Do not use the seasonal signal for a specific driving day.
Ski and mountain planning
Compared with a La Niña winter, the seasonal setup is less favorable for consistent low-elevation snow. Higher resorts retain more resilience, but base-building can be uneven.
Why this result can still be wrong
Seasonal outlooks are probabilistic. A region labeled warmer can still have cold outbreaks; a wetter region can still have long dry stretches. Shorter-term patterns such as the Arctic Oscillation, North Atlantic Oscillation and individual storm tracks can dominate a week or even a month.
