Could Super El Niño Disrupt Lake-Effect Snow Across the Midwest?
US · Published Nov 5, 2026
• A developing Super El Niño could reduce lake-effect snow across parts of the Great Lakes region this winter by favoring warmer temperatures and fewer Arctic air outbreaks.
• Lake-effect snow requires cold air to move over relatively warm lake waters, along with favorable winds.

Why It's Important?

The potential reduction in lake-effect snow is significant for communities across the Great Lakes region that rely on winter snowfall for various reasons. Economically, reduced snow can impact winter tourism, including skiing and snowmobiling, as well as businesses that depend on winter precipitation for their operations. For residents, it means a potential shift in winter activities and the need for different preparedness measures. Historically, strong El Niño events have demonstrated this effect; for instance, during the 2015-2016 winter, Cleveland saw only 24.9 inches of snow against its average of 51.4 inches, and Buffalo received 48 inches compared to its typical 85.7 inches. While these are historical trends and not guarantees, they highlight the substantial impact a Super El Niño can have on local snowfall totals, affecting everything from infrastructure maintenance to the overall winter experience for millions of people.
