A powerful spring cold snap brings more rain and snow to a soggy U.S. heartland Wednesday, putting more pressure on riverside communities from the upper Midwest to the Deep South.
The residents of Grafton, Illinois, north of St. Louis, will see the worst of the floodwaters through Friday as the Mississippi River peaks at more than 11 feet above flood stage, the National Weather Service says.
As rivers across the heartland swelled during the past two weeks, rising water was blamed for four deaths. Flooding threatens rivers in Illinois, Missouri, Iowa, Indiana, North Dakota, Mississippi and Michigan, according to the National Weather Service.
CNN's Jim Spellman reports live from St. Louis on the area's current flooding conditions.
