On November 5, some key battleground states in the United States experienced heavy rainfall and strong storms due to cold air. The heaviest rainfall was in Texas to the Missouri-Illinois border, including St. Louis, with flash flood warnings in effect. The rain may affect voters in the early morning, and the front will continue to move east, bringing showers to battleground states such as Minnesota, Wisconsin, Michigan, and southern Louisiana.
Rain can cause a slight drop in turnout, and Wisconsin saw the most severe weather, with the Storm Prediction Center issuing a Category 1 to Category 5 severe storm threat for the state.
