2024-2025 U.S. Winter Outlook

StormGeo forecasts a volatile winter season for potentially extreme weather events.

The main areas of concern for winter hazards across the United States are for:

• Enhanced risk for frequent winter storms across the Pacific Northwest
• Above normal snowfall across southern Canada, the Great Lakes, and Ohio Valley regions
• Extreme cold could occur at times.

Signals Influencing the Forecast

The forecast is strongly influenced by several long-range water temperature anomaly and technical signals across the Pacific and Atlantic basins. The primary water temperature signal is the ongoing weak La Niña event across the eastern tropical Pacific. The colder than normal water temperatures usually result in colder and snowier weather over most of Canada and the northern U.S., and milder and drier trends over most of the southern U.S.
