More than 460 flights were cancelled Saturday morning at Chicago's O'Hare International Airport and about 50 flights were cancelled at Chicago's Midway International Airport. In the Detroit area, many motorists were moving well below posted speed limits along freeways due to slushy conditions. The snowfall is part of a wall of hazardous weather that trekked from the Dakotas and across the Great Lakes states, headed toward New England. The U.S. National Weather Service has warned that conditions in the Northeast "could approach blizzard criteria." Strong wind gusts beginning Sunday afternoon could bring down snow- or ice-burdened tree limbs and power lines.
