A large complex of thunderstorms over Missouri gradually evolved into a bowing line of storms as it crossed southern Illinois. Locally damaging winds became increasingly more common as the storms organized into a line. The storms increased in intensity as a result of strong heating and destabilization during the morning hours. This round of storms was followed by another round of severe weather during the late afternoon and evening hours.
