Latest from weather.com lists temp as 5 at kickoff then dropping to 3 at 5pm and then to 3 at 6pm. It lists chance of snow at 20 percent at kickoff and 30 percent for the rest of the game starting at 5pm. Wind will be pretty good at around 14-18mph so that will put most of the game windchill temp around -17 degrees.
