Elections are affected by weather. Political pundits have always thought so. Now a team of political scientist have confirmed it.

Brad T. Gomez of the University of Georgia, George A. Krause of the University of Pittsburgh, and Thomas G. Hansford of the University of California, Merced, studied a combination of weather factors and election turnouts during presidential elections from 1948 to 2000.

The evidence they collected indicates that rain or snow does decrease voter turnout and effects Democrats more than Republicans. According to an article on weather.com with an analysis of their results, for every inch of rain on election day, Republican’s gained a 2.5% increase in voter share.

Today’s forecast across the United States calls for mostly good weather. Most of the US will be experiencing sunny to partly cloudy conditions with a slight cooling trend. Texas may experience rain and thunderstorms, with parts of the storm spreading across the South with showers and light rain in parts of Florida, Tennessee, Alabama, and Georgia.
