MADISON (WRN-WSAU) Better bring your rain gear, if you’re planning to see the president visit Wisconsin on Thursday. An approaching cold front could make conditions wet and windy for President Barack Obama’s campaign stop on the University of Wisconsin campus in Madison.

The National Weather Service is predicting a 40 percent chance of showers and thunderstorms¬. People attending the event will not be allowed to bring in umbrellas, which may be just as well, since winds could gust up to 25 miles per hour.

The President will have left Wisconsin before that same cold front pushes temperatures down from the low 70s for a Thursday high to the 50s on Friday.

The Obama rally on Bascom Hill is expected to mean big crowds, road closings and traffic at a standstill near the campus. Gates for the event will open at noon.

The last time the President was in Madison two years ago more than 26,000 people showed up.
