Fall Forecast: El Niño Fuels Warmth Coast-to-Coast
4 Sep
Summary
- El Niño is expected to dominate weather patterns across the U.S. this fall.
- Florida experienced a record-breaking hot summer with multiple cities setting records.
- Above-average temperatures are predicted nationwide from September through November.
Summer's intense heat is showing no signs of immediate retreat across much of the United States, with forecasts predicting a lingering warmth well into the fall season. El Niño's strengthening is identified as the primary driver, influencing weather patterns from September through November. This phenomenon is expected to bring above-average temperatures to nearly the entire country, with the exception of a small area in the Ohio Valley.
Florida, in particular, endured a record-shattering summer, with many cities experiencing unprecedented heat waves. On August 18th, at least ten Florida cities tied or broke high-temperature records, with Tallahassee and Miami reaching triple digits. This persistent heat was attributed to a high-pressure system creating a heat dome over the Southeast.
The strong El Niño signal provides high confidence that it will dictate much of the nation's weather throughout the fall and winter. While El Niño is anticipated to bring much-needed rain relief to the southern tier of the country, the Northwest may continue to grapple with wildfire activity into early fall. Despite the overall warm outlook, isolated cold snaps remain a possibility as the season progresses.
