Super El Niño forecast boosts southern U.S. snowfall for winter 2026‑27

Six seasonal climate models released in October indicate a clear Super El Niño influence on the Winter 2026/2027 snowfall outlook across the United States and beyond.

Snowfall distribution

The models agree on a pattern of more snow across much of the southern and central United States and less snow for the northern United States, southern Canada, and most of Europe. The projected increase is most pronounced in three regions:

• Ohio Valley and Central Midwest: about +2.7 inches of snow compared with the previous forecast.
• Southern Plains and Texas: about +2.0 inches of snow.
• Southwest and Southern Rockies: about +1.5 inches of snow.

Timing of snowfall

The consensus also points to a slow start to the snow season in December, followed by the strongest snowfall signal arriving in the second half of winter and likely extending into early spring. This timing aligns with the characteristic Super El Niño signature identified by the model suite.

El Niño classification

According to a regional forecaster tracking the event, the current El Niño episode registers an Oceanic Nino Index above +2.0, a level described as “Very Strong/Super” though the term “Super” is not an official classification.

These model outputs provide the most recent quantitative guidance on snowfall expectations for the upcoming winter season.
