Seems like all of our tor warnings in this region (MKX/LOT/eastern DVN/southern ARX CWAs) these days happen at random on marginal/no-risk days, and either are never confirmed or are landspouts/cold-air funnels. I mean, I don't expect sig tors to be exactly common but a few legit EF1-2s per year would be, I dunno...(used to be) normal?
In retrospect, 2015-16 were really busy in northern IL with Rochelle, the two June 22nds and 3/15/16.
