The wider storm

During the afternoon and evening of April 18, 2024, discrete supercell thunderstorms developed along a cold front moving through the bi-state area. These storms were initially mainly capable of producing large hail and damaging wind gusts, but become tornadic as additional thunderstorms formed along the front. Due to the additional thunderstorms storms congealed into a QLCS that impacted portions of southwestern Illinois. The QLCS was responsible for several tornadoes and instances of straight line wind damage in this part of the area. Fortunately, no injuries or fatalities were reported with these thunderstorms.

Began near Okawville (38.4400, -89.5300).
