A weather system moving across the United States is forecast to bring rain, wind, and potential thunderstorms to central states on Election Day, Tuesday, Nov. 3, 2026. The storm is expected to enter the U.S. on Saturday night, Oct. 31, and move through the Southwest before reaching the Great Plains and Upper Midwest by Tuesday. Meteorologists report that while the risk of flooding rain on Tuesday remains low, travelers may encounter road ponding in affected areas.
The storm began off the West Coast and is projected to bring heavy rain to Arizona, New Mexico, Utah, and Colorado from Sunday, Nov. 1, into Monday, Nov. 2. In Phoenix, firefighters rescued six people from flash flooding on Friday, Oct. 30. As the system moves east, it is expected to bring blustery conditions to the Plains, with wind gusts reaching up to 40 mph in Kansas and 50 mph in Nebraska on Tuesday.
Forecasts for states with midterm races indicate varied conditions. Michigan and Iowa are expected to see rain for portions of Election Day, with Iowa’s heaviest totals predicted for Monday evening through midday Tuesday. In Texas, rain is likely in eastern and coastal areas, where severe thunderstorms with damaging winds are also possible. Conversely, Georgia, North Carolina, and Ohio are forecast to remain mostly dry with high temperatures ranging from the 60s to the 80s.
The weather conditions may affect voters who have not yet participated in the 2026 midterm elections. While more than 49 million people have already cast ballots through early voting as of Oct. 31, millions of others remain eligible to vote in person on Tuesday. The storm's path covers several states with key races, including Iowa, Kansas, Michigan, and Texas. Research cited by CNN Weather indicates that rainfall and active weather typically correlate with lower voter turnout, whereas clear conditions are associated with higher participation.
Residents in the central United States, stretching from the Great Plains and Upper Midwest to the Lower Mississippi Valley and western Gulf Coast, will notice changes in their daily commute to polling stations. In states like Kansas, voters will experience wind gusts between 20 and 30 mph, while high temperatures across the eastern half of the nation will be 5 to 20 degrees Fahrenheit above average.
These weather patterns could influence the final tallies in races that are currently undecided. Beyond the immediate impact on Tuesday's turnout, severe weather in the Southwest has already required emergency interventions, such as the rescues in Phoenix. The storm is expected to clear the central U.S. following Election Day, though forecasts may continue to adjust as the system's path becomes more certain over the weekend. Election Day remains the final deadline for in-person voting on Nov. 3, 2026.
