Winter 2026/2027 Snowfall Forecast: How October Data Changed Your Region’s Outlook

The latest October data from six seasonal models now broadly agree on the overall Winter 2026/2027 snowfall pattern. A Super El Niño footprint is clear, with more snow across much of the southern and central United States and less snow for the northern U. S., southern Canada, and most of Europe. The models also agree on the timing: a slow start to the snow season in December, with the strongest snowfall signal arriving in the second half of winter and likely continuing into early spring. That is a clear Super El Niño signature. In this article, I present the full set of snow maps, including the change from the previous month’s snow forecast, the snow spatial distribution, and the forecast for ski areas. I also added a Snowfall Explorer where you can check the detailed snow forecast for your own state, province, region, or country in the United States, Canada, and Europe.   October Update: What Changed in the Snowfall Forecast   The image below shows how the latest ECMWF snowfall forecast changed from the September to the October run. Blue colors show where the new run has more snow than before, and brown colors show where there is less. This is not yet the actual forecast, but the change in the winter snowfall trend since the previous month. You can see a clear shift toward more snow across the southern and central United States. A large increase is visible in the Ohio Valley and Central Midwest (around +2.7 inches), the Southern Plains and Texas (+2.0 inches), and the Southwest and Southern Rockies (+1.5 inches). At this range, the snow trend matters most, not the raw numbers. The Northeast gained snow in the latest run, especially in Maine, New Hampshire, and Vermont. At the same time, the October run took some snow away from the Northern Plains, the Upper Midwest, and parts of Montana and Wyoming. For Canada, the October run added snow over Quebec (+6.7 cm), British Columbia and Atlantic Canada. But we can see that the Prairies and Ontario lost a few centimeters compared to September forecast data. In Europe, the October run brought a weaker snow outlook. The ECMWF change map below shows less snow than in September across most of Europe, with the largest drops over the southern and central parts. These changes do continue an established trend, giving more confidence in the overall winter pattern across the Northern Hemisphere.
