Pockets of flash flooding occurred across southern Illinois. A narrow swath of torrential rainfall occurred from Cape Girardeau, MO northeast across the Marion/Carbondale area, where streets were closed. A surface low pressure center tracked rapidly north-northeast from Arkansas to the upper Mississippi Valley, dragging a warm front north across southern Illinois. Instability was adequate for thunderstorms. A very moist air mass resulted in excessive rainfall rates, which produced flash flooding
