Vibrant fall foliage is anticipated in 2026 for New England, upstate New York, and parts of California, thanks to favorable spring and summer weather followed by cool autumn nights. The Midwest and Cascades may also enjoy colorful displays if dry, cool conditions align. However, drought and wildfire stress are expected to dull leaves in the Rockies, interior Northwest, mid-Atlantic, and Carolinas. Trees in stressed regions like the Rockies and Southeast may drop leaves early, while warmer conditions in the Ohio and Mississippi Valleys could delay peak color. Most other areas, including the Great Lakes and Northeast, should peak on schedule. https://www.accuweather.com/en/weather-forecasts/fall-foliage-forecast-2026-where-to-expect-the-best-color-across-the-us/1924680
