MINNEAPOLIS (AP) — A storm system stretching from the Gulf Coast to the Great Lakes buffeted the central U.S. with heavy winds, rain, hail and snow, forcing flight cancellations, creating treacherous road conditions and killing at least three people, including a sleeping 2-year-old Louisiana girl. In the upper Midwest, the early spring storm brought snow to a region pining for sunshine and warmth. More than 200 flights were canceled Saturday at Minneapolis-St. Paul International Airport and blizzard conditions forced the airport in South Dakota's biggest city, Sioux Falls, to remain closed for a second straight day.
