Biting winds and bone-chilling cold will bring challenges for football players and fans this weekend.
Following fronts moving through much of the country, a drastic change in temperatures this weekend could cause problems for those trying to enjoy football.
Those tailgating, being live spectators or playing one of America's pastimes this weekend should exercise caution, bundling up and taking breaks indoors when possible.
Although it will be noticeably colder on Saturday in the Northeast for NCAA football games, the bitter cold really moves in for Sunday, just in time for NFL games in the region.
In the Ohio Valley, the Steelers take on the Cleveland Browns with highs only in the mid-20s. Despite some sunshine for the game, the chilling winds will make it feel more like temperatures are in the teens. A few lake-effect snow flurries are also in the forecast for Sunday.
Also in the AFC North, the Baltimore Ravens will be battling the cold as they take on the New York Jets. Kick-off temperatures will be near freezing with winds gusting above 25 mph.
Both the New York Giants and New England Patriots have home games this weekend, and will only have highs near 30, leaving fans and players frozen.
The early games across the northern tier will still be feeling like winter.
The Vikings will be visiting a very cold Lambeau Field to take on the Green Bay Packers, where the highs will once again struggle to reach the lower 20s. However, some sunshine is expected for the game.
The center of the country will have cold making an impact on games as well. As the Kansas City Chiefs will host the Chargers and the St. Louis Rams battle the Chicago Bears, it will barely reach the lower 30s.
