Not much likely to change with this forecast, as a cold pattern locks in on Thursday (some lake effect snow in the region through Friday) and continues through the weekend, bringing well below normal (40/28F is the normal hi/lo on 11/30) temps for Saturday, with highs around 30F and dropping into the mid/upper 20s during the game. Winds look to be in the 10-15 mph range with higher gusts, so wind chills could easily be in the teens and it'll likely be mostly cloudy with a low chance of snow flurries (accumulations are unlikely, but not out of the question, with regard to a coating or a quick 1/2"). I'm guessing the MSU fans will be able to handle this - it's not difficult, as this is expected at the end of November in Michigan. A win to go 7-5 would be nice.
