The rain chances will begin to taper off after 4 or so. They have the arrival time of around 9 and thats pretty much dead on, maybe a little earlier. Yeah, these storms are gonna grow in intensity and coverage as the day continues on. After the game though, tailgating will be probably a little bit better than it will be this morning. But that NOAA forecast is usually a very good tool to get good quick info on the area, and its pretty accurate, so I would bookmark that page because I use it all the time. It seems pretty accurate to be except for I think the rain will start before 9 o clock.
