Nasty winter weather wreaked havoc in 35 states Sunday, snarling holiday travel. Heavy snow fell in the Midwest, paralyzing a stretch from Oklahoma to Wisconsin. In the Northeast, unseasonably warm temperatures meant flash-flood warnings, and New York's Central Park hit a record 65 degrees. Meanwhile, New England and Canada were hit by a nasty ice storm, which left thousands without power, including Toronto Mayor Rob Ford. About 1,105 flights were canceled and 11,518 flights were delayed through Sunday night, according to FlightAware.com.
