Weather forecasts change, but everyone is in agreement that it's going to be very, very cold during Sunday's AFC Championship Game between the New England Patriots and Kansas City Chiefs at Arrowhead Stadium. Early reports suggested an "arctic blast" is going to be over Kansas City by the 6:40 p.m. ET kickoff time, which would make for temperatures in the single digits. The Arrowhead Stadium grass, which has had issues in the past, also must deal with the icy temperatures and could result a less-than-ideal playing surface.
