Very nice. It looks like my cell merged with a another storm from just south and produced your tor.
One small thing I'll always regret about that chase was leaving my original position just to the south of Good Hope. Sat there for a short while with an excellent view of the approaching wall cloud, but repositioned a bit south to get out of the large hail threat. If I would have stayed there I would have captured a very nice long-lived time lapse of the approaching sup and evolution of the developing tor at very close range, as it passed very close to the original location.
Here's where I wish I stayed put...
