"Mesoscale Accident" Sneaky Tornado at Cullom, IL

One of the things the drove me crazy growing up in Illinois was "mesoscale accident" days... or days when photogenic funnels or tornadoes occurred when we weren't expecting it. I've since obsessed over finding any little reason updrafts should rotate, be it along spinny boundaries, swirling MCVs or otherwise. I love finding secret little funnels and tornadoes. One such opportunity presented itself on July 20th... a lazy Sunday with a curious boundary to my north. Let's go find a tornado.
