Wow, I'm surprised nobody is talking about this one, lol. SVRs and TORs rapidly being issued in northern IL ahead of a damaging wind producing diurnal MCS. Looks like it is still intensifying as it is drawing in 75+ dewpoint air and 3000 SBCAPE. Unidirectional windspeed shear will make this thing capable of doing 70+ mph wind damage. I'm definitely agreeing with the MDT out for much of northern IL. Embedded circulation on a storm near Dekalb that had a brief TVS on it has prompted a tornado warning for Dekalb and Kane. Look out Chicago Metro!
