Sharp cold wave shocks upper Midwest, temps to -36

BISMARCK, N.D. (AP) - In the upper Midwest, residents are bundling up or just staying indoors as a wave of bitterly cold air barrels south out of the Arctic on the heels of a fast-moving blizzard.
    Some schools closed because of the cold. Temperatures hit the single digits as far south as Kansas and Missouri.
    The coldest air spilled across the Canadian prairie into the Dakotas and Minnesota. Grand Forks, N.D., dropped to a record low of 37 degrees below zero this morning, lopping six degrees off the old record set in 1979.
    Wind chill warnings are posted for much of Wisconsin, South Dakota, Iowa and Minnesota.
    The leading edge of the cold air is expected to strike the Northeast, mid-Atlantic and South late today and tomorrow.
    The National Weather Service has posted winter storm warnings for parts of Michigan, northern Indiana and Ohio’s northwest corner.
    Up to 11 inches of new snow is possible in Detroit.
