Winter 2026/2027 Forecast Points to Colder Shifts and More Snow in the US

The November forecast data for the 2026/2027 winter season points toward a colder and snowier pattern across large parts of the United States, while Europe is expected to stay mild. The forecast also aligns closely with past Super El Niño winters, specifically the 1997/1998 season, and highlights a looming Polar Vortex disruption shown by two major models for mid-winter. Changes in pressure systems have driven these updates, with a deepened low-pressure zone over the Atlantic and the United States, combined with an amplified high-pressure zone over Canada. These shifts create a colder temperature trend across the western United States and the Southeast, while the upper Midwest, the Northeast, and Canada continue to see warmer anomalies. Alongside the temperature shifts, the latest forecast shows an increase in expected snowfall across much of the western and northern United States, the Appalachians, the far northeast, and southern Canada. Meanwhile, Europe anticipates warmer temperatures and milder westerly to southerly flows due to strengthening high-pressure anomalies.
