Forecasters predicted freezing rain and snow flurries in Iowa on Sunday, a day after snow and ice plastered the Midwest, disrupting airport and highway traffic and leaving at least three people dead. Hundreds of flights were canceled at airports in Des Moines, Chicago and Milwaukee on Saturday, with officials closing Des Moines International Airport for several hours after a United Airlines plane slid off a taxiway as it headed to a runway for a flight to Chicago's O'Hare. None of the 44 passengers was injured and the airport reopened by mid-afternoon. At Dane County Regional Airport in Madison, Wis., an incoming Mesa Airlines regional jet flying for United Express slid off the pavement after failing to make a turn onto a taxiway, but no injuries were reported among the 25 passengers. The National Weather Service had posted winter storm and ice warnings across parts of Nebraska, Iowa, Wisconsin, the eastern Dakotas, Illinois and northern Michigan, but many of the warnings were lifted later in the day. In Minnesota, Duluth received nearly 8 inches of snow, according to a report of the Associated Press.
