Yes, Parkersburg is often overlooked in the conversation but I think one of the most impressive of the relatively small club of official EF5s. I was chasing that day but only made it to southwest Wisconsin (flying blind other than occasional calls to a nowcaster, no in-car data back then), where I basically just let the now non-tornadic storms roll over me at Lancaster.

Those videos of Cordova are really spectacular. The perfectly sculpted and widely visible low-level supercell structure is certainly rare for Dixie Alley. Many of the storms that day were unusually visible/photogenic (apart from trees) by the region's standards. Even Hackleburg, which was probably the closest to a Dixie"standard" murky rain-wrapped wedge, had periods where it was quite visible from certain angles.
