A stationary boundary slowly began to move north across central Illinois on Sunday October 7th triggering thunderstorms from St. Louis to Chicago, a couple of which began to rotate along I-72 and I-55 from Champaign to St. Louis.
I intercepted a storm that developed near Clinton, IL and followed it northeast into Champaign County. It went through several cycles where it appeared to be close to producing a tornado but a cold, strong RFD undercut and ended every real attempt at tornadogensis.
Still, a very fun late-season storm!
