NORMAN, Okla. — The conditions are ripe for a series of storms to gain strength and buffet Middle America over the next two days, with hail and tornadoes possible in parts of the nation’s geographic heartland, forecasters warned Wednesday.
Large hail, damaging winds and a number of tornadoes were possible Wednesday from the southern Plains eastward to Illinois. The focus shifts to the mid-Mississippi River Valley for Thursday, including Chicago, Indianapolis and St. Louis.
Thunderstorms were already rolling through Indiana and Missouri at dawn, and the Storm Prediction Center said multiple bouts of severe weather would develop through the day. The highest chance of tornadoes Wednesday extended from the Kansas-Oklahoma border south of Wichita, Kansas, to the St. Louis area — with storms forming in the afternoon and early evening.
Another day of warmth Thursday, mixed in with humidity, instability, an approaching front and the jet stream, would contribute to steadily worsening weather.
