Understanding the 2025-2026 Winter Storm Season Outlook in the United States

The 2025-2026 winter storm season in the United States is anticipated to be influenced by a weak La Niña event, leading to varied weather patterns across the country.

What is La Niña and How Does It Affect Winter Weather?

La Niña is a climate phenomenon characterized by cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean. This condition can significantly impact weather patterns, often leading to:

  • Northern Regions: Colder and snowier conditions.
  • Southern Regions: Warmer and drier conditions.

For the 2025-2026 winter, a weak La Niña is expected to persist through December 2025 to February 2026, with a transition to ENSO-neutral conditions likely by early spring 2026. (weather.gov)

What Are the Temperature and Precipitation Forecasts?

The National Weather Service's Climate Prediction Center has released the following outlook for December 2025 through February 2026:

  • Temperature Outlook: Above-normal temperatures are favored across much of the East Coast, Southeast, Gulf Coast, Texas, the Southwest, and California. (weather.gov)

  • Precipitation Outlook: Below-normal precipitation is expected in parts of the Southwest and Southeast, while above-normal precipitation is anticipated in the Northwest and parts of the Ohio Valley. (weather.gov)

How Will This Affect Different Regions?

  • Northeast and Great Lakes: The combination of a weak La Niña and other atmospheric factors may lead to a colder and snowier winter than initially expected. (climateimpactcompany.com)

  • Mid-Atlantic and Southeast: These regions are likely to experience milder temperatures and drier conditions, with a higher probability of above-normal temperatures. (weather.gov)

  • Southwest: The Southwest is expected to have above-normal temperatures, with a greater than 70% chance of this outcome. (weather.gov)

What Are the Implications for Winter Storms?

While a weak La Niña typically leads to milder conditions in the southern U.S., the northern regions may still experience significant winter storms. The interplay between La Niña and other atmospheric patterns, such as the North Atlantic Oscillation (NAO), can influence the frequency and intensity of storms. For instance, a negative NAO phase can allow cold Arctic air to spread across the eastern United States, leading to colder and snowier conditions. (weather.gov)
