NORMAN, Okla. (AP) – The Storm Prediction Center says a portion of the Ohio and Mississippi valleys could see strong winds and perhaps tornadoes this afternoon.

The Oklahoma-based forecasters warned there is a “moderate risk” of severe weather in an area from Louisville, Ky., to near Tupelo, Miss. A slight risk of severe weather surrounds that region, from the central Gulf coast to southern Illinois, Indiana and Ohio and into the western Appalachians.
 
A cold front is approaching the region from the west. The Storm Prediction Center says thunderstorms would begin forming in a line from St. Louis to Texarkana, Ark., then move eastward. The storms could contain damaging winds, and some could contain tornadoes.
 
While that severe weather is developing, there's a chance of heavy snow in parts of Iowa, Minnesota and Wisconsin.
