New Storm Slamming Midwest, East Coast

(Undated) -- There's no rest for the weary as a quick-moving storm is expected to dump up to half a foot of snow from the Midwest to the East Coast. Forecasters say snow will keep falling through Tuesday. The heaviest snowfall is expected today in Wisconsin, Michigan, and northern Illinois, including Chicago. More than 300 flights have already been cancelled at Chicago's O'Hare Airport.
