12z Guidance is pretty impressive, HRRR/NAM 12k/NAM 3k/CAMs all offer up decent scenarios for fast moving tornadoes, with HRRR being the least impressive with too many discrete cells firing and creating a line with some interference it seems. Seems Ohio/East KY maybe more in the threat area, with pretty much every high res model showing these cells making their way well into Ohio in an impressive environment. 1730z Day 2 SPC outlook will be interesting.
