Super El Niño to Shape Winter 2026/2027 Snowfall
The Winter 2026/2027 snowfall forecast reveals significant impacts from a developing Super El Niño, which is expected to reshape global weather patterns. According to the latest September update, snowfall trends across the United States, Canada, and Europe will vary widely. Reduced snowfall is anticipated in the Northeastern and Northwestern U.S. and parts of Canada, while above-normal snowfall is forecast for the Central and Eastern U.S. This Super El Niño event, characterized by ocean temperatures exceeding 6°C (11°F) above normal, will amplify the Pacific jet stream, influencing storm tracks and precipitation. Historical data suggests similar El Niño events have led to increased snowfall in regions like the Sierra Nevada and Southern Rockies, while suppressing snowfall in the Pacific Northwest and Great Lakes. Europe may see below-normal snowfall in many areas due to mild Atlantic flows. The forecast will continue to evolve as the El Niño peaks in late fall and early winter.
