Well other than the early Monday morning HRRR and NAM nightmares showing a possible big outbreak *perhaps* getting to Central Ohio, there was always the likelihood that it would be worse down near the Ohio River and Kentucky.
When the moderate risk was held over that area, there was a massive social media twitter meltdown among the amateur storm chaser nerds. They were attacking some forecaster named Broyles or something and going nuts. Then you had the long discussions and a tardy issuance of the moderate risk Mon afternoon smack dab over Central Ohio, way too far north without more model run indicators. By Monday evening, it was obvious that should be moved southwest, which it eventually was.
I know this seems unlikely, but is there a chance that the moderate risk was issued out of pressure from the social media freakout and the overperformance of the March Western Ohio tornado event?
