Here is an overlay of the NAM supercell composite parameter (which is normally overdone with CAPE) with 500mb wind barbs on Friday afternoon. The high supercell composite parameters are a result in excellent placement of CAPE/ SRH/ 0-6km shear. This seems like a very good setup for reasonably fast-moving severe storms for NW Ohio and into pretty much all parts of Ohio, and possibly starting off with severe storms in northern Indiana.
