A polar vortex has descended upon the northern and central U.S., bringing sub-zero temperatures, "life-threatening wind chill," and the coldest weather felt in decades. Twenty-six cities are under wind-chill warnings or watches. Chicago and Minneapolis will record temperatures of 20 to 30 below. In North Dakota, wind chills were as low as negative 50 degrees.

  • School is closed in the entire state of Minnesota, as well as in districts in Illinois, Indiana, Iowa and Wisconsin. Even though today is a snow day, some ski areas, sledding hills, and ice rinks in Minnesota and Ohio are also closed until Tuesday.

  • Frostbite could set into exposed skin in as little as five minutes. (See also: The Cold Hard Facts of Freezing to Death.)

  • Green Bay Packers fans at Sunday's Packers-49ers game in Green Bay, Wisconsin, were grilling frozen beers, to thaw them back to a liquid state.
