Bring your rain gear to the stadium on Saturday. You'll probably need it.
I'll have my full game day weather post Saturday morning, but rain is in the forecast for several games involving Big Ten teams.
Here are some of the potentially affected sites -- I only listed sites with better than 20 percent chance of rain -- according to weather.com:
South Bend, Ind. (Michigan at Notre Dame, 3:30 p.m. ET): Forecast calls for showers and thunderstorms throughout the game, 60-70 percent chance of rain.
Columbus, Ohio (Miami at Ohio State, 3:40 p.m. ET): Forecast calls for showers around kickoff, thunderstorms possible later in the game, 60 percent chance of rain.
Evanston, Ill. (Illinois State at Northwestern, noon ET): Showers possible around kickoff, weakening throughout the game, 30 percent chance of rain.
West Lafayette, Ind. (Western Illinois at Purdue, noon ET): Thunderstorms possible around kickoff, chances increase throughout the game, 40-60 percent chance of rain.
Right now, it looks like you'll stay dry in Iowa City, Minneapolis, Madison, Champaign and Tuscaloosa, but at this time of year, you never know with the weather. The safest place to be Saturday? Ford Field in Detroit, where Michigan State and Florida Atlantic play indoors.
So who has the edge in the rain? Typically teams that can run the ball effectively. I give Michigan and Ohio State slight edges if it pours.
