First off beware of slick roads both going to and from the game.
Assuming there is going to be next to no tailgating I won't bother with that time frame. I would count on there being light rain at least off and on the whole game and wouldn't count out a wintry mix as well. Temps are going to be just a few degrees above freezing all day with winds sustained 15-20 gusting 25+.
If this were to move north or south a little there might be more of a mix/snow or all rain but regardless it is going to be cold, wet and windy. Basically a miserable day to be outside so kudos to those of you making the trek but I am going to count going to the KU game as my 7th home game of the season.
Up here along the IA/MN border they keep changing some snow to rain. We were at just short of a foot, now a couple inches of snow and the rest rain. Hope it pushes further north, sunday stands a chance to melt much of the ice we could be left with.
