The Midwest snowstorm hit eight states overnight, and first claimed Sunday’s NFL match-up between the New York Giants and the Minnesota Vikings, forcing it to be moved to Monday. (The Giants were stuck in Kansas City overnight.) And now the Metrodome's roof has collapsed under the weight of snow (watch the video here), forcing the game to take place in Detroit. Twenty inches of snow blanketed parts of the region on Saturday, wreaking havoc on the roads. Blizzard warnings are in effect Sunday for much of northern Illinois, Iowa, Minnesota, Wisconsin, North Dakota, South Dakota, Missouri, and Michigan.
