LOUISVILLE, Ky. (AP) -- The National Weather Service says at least two people have been injured after powerful spring-like storms spawned tornadoes in Indiana, Kentucky and Mississippi.

Forecaster Ed Agre says two people were injured after a twister touched down just after 4 p.m. Tuesday in southern Mississippi's Marion County, destroying a mobile home and damaging other homes in the area.

Earlier in the day, a tornado that slammed into the Louisville, Ky., metropolitan area was blamed for tossing a pair of tractor-trailers off of the freeway and snarling traffic. Officials say a line of storms that raked Indiana spawned a weak tornado that struck an airport in the Ohio River city of Madison.

Storms in the St. Louis area caused tornado sirens to blare in several of the Missouri city's communities early Tuesday.
