As night approached, the death toll rose in areas affected by extreme weather in the Midwest and the South. Towns have been wrecked and the number of people missing is unclear.

The Associated Press reports that at least 28 people have been killed, including 14 in Indiana and 12 in Kentucky. (Note: This number is bound to change, and we'll update as we have more information.)

The damage was greatest in southern Indiana, NPR's Karen Grigsby Bates tells our Newscast unit. She reports a sheriff described the small town of Marysville as being "completely gone."

The storm is expected to continue overnight throughout parts of the Southeast, the Midwest and down into the Gulf States.
