Was a high-profile, High Risk day for AL, but we were on the edge of the risk, which had gotten trimmed down just before it hit.
I do wonder what it would take for the SPC to go with the dreaded 60% hatched area for violent tornadoes. I know it has happened once in 200ybut that was before the EF-SCALE started being used.

Cookville is the most recent freak example of a violent tornado happening in a very marginal threat day.
Never will that instance not be insane.

Winterset, IA 2022 (although that only really appeared marginal in the days leading up to it, SPC did introduce a 10% contour during one of the Day 1 updates prior to the event).

One thing I'm learning is how important lapse rates and 3CAPE are.

Frankly, I'm a little surprised they didn't use it on 4/27/11. Maybe simply the then relatively fresh (5 years) memory of the fact that the one time they had used it previously (4/7/2006) didn't really live up to being that bad (it was still a substantial outbreak, but would have been adequately covered by a "normal" high risk (30% hatched).

I know April 14, 2012 was very close as well. There was a 45% hatched area for violent tornadoes from S Central Kansas to like Central Nebraska. It didn't perform as well as others thought but it still was at least a high-end moderate risk or low-end high risk.
