Wider weather episode

A Mesoscale Convective Vortex (MCV) generated by prior convection across Kansas and Missouri tracked into west-central Illinois during the afternoon of July 10th. Despite minimal instability, the enhanced low-level vorticity created by this feature was enough to trigger several rotating thunderstorm cells across west-central Illinois. Five brief tornadoes touched down across portions of Schuyler, Cass, and Morgan counties...with minor damage reported. Meanwhile further south, flash flooding occurred across parts of Clay County as thunderstorms with torrential rainfall skirted well south of I-70 during the evening.
