What happened
NOAA’s Climate Prediction Center issued its eight-to-14-day outlook on October 29, predicting above-normal temperatures for most of the U.S. east of the Rockies—including Alaska and Hawaii—from October 30 to November 5. The forecast is based on an amplified 500-hPa height pattern over North America, per NOAA’s October 29 discussion. This pattern suggests relatively warm and dry conditions for Election Day, though localized showers and thunderstorms are possible in the Central U.S., including Chicago, Minneapolis, and Dallas.
Who is affected
Voters across the U.S. east of the Rockies, Alaska, and Hawaii will experience above-normal temperatures on Election Day, with highs in the 70s and low 80s. Regions like Columbus, Ohio, are forecast to reach 76 degrees, while Philadelphia may see 70 degrees. The Central U.S. could face showers and thunderstorms, potentially impacting turnout in cities like Chicago and Dallas.
The forecast highlights several key figures: Election Day highs of 76 degrees in Columbus, 70 degrees in Philadelphia, and a record-breaking 87 degrees in Columbus on October 13. Additionally, wind gusts reached 44 mph during a storm in Philadelphia on October 15–16.
What to do next
Voters should check local forecasts for real-time updates, as conditions can change. The National Weather Service advises monitoring evolving forecasts, especially for potential showers in the Central U.S. Early voters or those with flexible schedules may avoid Election Day weather uncertainty.
What we know and don’t know
We know that above-normal temperatures are expected nationwide east of the Rockies, but we don’t yet know the exact timing or intensity of localized showers or thunderstorms. The forecast is based on models with inherent uncertainty, and conditions could shift as Election Day approaches.
