El Niño to Bring Wetter Fall to Southwest, Drier Conditions in Northeast
El Niño is expected to significantly influence weather patterns across the United States this fall, according to AccuWeather forecasts (Newsweek, 2026-08-10). Wetter-than-normal conditions are anticipated in the Southwest, including California, Nevada, Arizona, Utah, and New Mexico, as well as the Gulf Coast and Southeast. Conversely, drier conditions are forecast for the Pacific Northwest, Great Lakes, and Northeast. Warmer-than-average temperatures are expected in the northern Plains, upper Midwest, and Southeast. The fall transition is predicted to be slower in the eastern U.S. and Pacific Northwest, while the central Rockies may experience a faster seasonal shift. AccuWeather also predicts vibrant fall foliage in the northern U.S. and muted colors in the central Rockies and Southeast.
