We had just gotten a new color (!) TV, and I vaguely remember watching the Packers battle the Cowboys on Dec. 31, 1967, in what came to be known as the "Ice Bowl." It was 15F below at Lambeau Field, with a windchill of 44F below. Whistles froze to the lips of referees. Members of the band were hospitalized for hypothermia. Cars wouldn't start; one Green Bay player had to hitchhike to the stadium.
It won't be quite that cold Sunday at TCF Stadium as the Vikes take on the Seahawks, but the risk of frostbite and hypothermia will be high. I expect game-time temperatures of 5 below, a windchill of 30 to 35 below. The "no exposed skin" rule will definitely apply Sunday and again Tuesday as a second spoke of subzero fun rotates across Minnesota.
It's rare to get this cold without some snow. I see two chances to freshen up our snow cover: an inch of slush later today, maybe a couple inches Friday into early Saturday as a weak storm spins up along the leading edge of truly polar air.
Next week should be the coldest of the winter. I predict Sunday's game may rival the legendary 1967 Ice Bowl.
