In The West Wing, as President Jed Bartlett is running for re-election, one character gets nervous because it's raining in Oregon on Election Day. A later scene shows Will Bailey, played by Joshua Malina, precipitously looks to the heavens and asks for rain just hours before the polls close, leaving his candidate, we are led to believe, the winner.

Rain, the theory goes, depresses voter turnout. Other weather can also have a dampening effect on turnout. Here, then, with the Official Real Clear Politics Election Day Weather Forecast, special RCP Weather Correspondent Steve Shepard:

A cold front currently across the Ohio River valley will affect weather conditions in the following areas, bringing with it light precipitation and the coldest air of the season thus far.

Virginia: Mainly light rain showers associated with a cold front should clear out from west to east (overnight across the Blue Ridge, by daybreak in the Northern Va. suburbs of D.C., and by lunchtime in the Tidewater area), and skies will clear by afternoon. It will be breezy, with high temperatures ranging from the mid 40s across the higher elevations, to 55 in the D.C. suburbs, and into the lower 60s south and east.

New Jersey: Morning showers will give way to sun, clouds, and brisk winds in the afternoon. Highs will range from the upper 40s north and west to the mid 50s down the shore.

Mississippi: North: Sunny and cooler, with highs in the mid 50s. Along the Gulf Coast, a slight chance of a shower, otherwise more clouds than sun, with temperatures in the upper 60s to near 70.

Kentucky: Sunny, and much colder, with highs only in the 40s across much of the Commonwealth, which is between 20-30 degrees colder than today. Breezy along the Cumberland Plateau.

Toledo, Ohio [Ed. note: The primary election to replace the late Rep. Paul Gillmore takes place in Ohio's 5th District tomorrow]: Cloudy and colder. Scattered rain and snow showers are possible, though there will be no snow accumulation. Brisk west winds will make temperatures feel a bit colder than the lower 40s.
