Yea, 1,500 SBCAPE, bit of a lee trough, good ll lapse rates, and okay mid level lapse rates. Also got a belt of 40kt shear. Maybe some sneaky storms in the NW suburbs today?
Only saving grace for many is having this system be a few hours early (can't maximize surface instability) and a bit more progressive than forecast. Otherwise, double digit rainfall totals might be more widespread.
Pretty safe to say some of the CAMs are busting hard and seem to be underestimating the morning activity. HRRR appears to have missed all of the pre-game convection from I-83 northeast into PA.
