The timelapse finally finished rendering around 10:00 AM or so. Came out so much better than expected! As we headed southeast out of Wichita Falls towards Henrietta, the rain that had been shrouding the storm began to clear and reveal what looked like decent structure. We headed south out of Henrietta on 148 and I started taking pictures at 4:48 PM. We expected the storm to move over us fairly soon, but I figured I'd try to timelapse it anyway because what harm could it do? Instead, the storm went through some sort of cycle and possibly a boundary merger (I wasn't watching radar at the time; too mesmerized by the storm). This resulted in it sitting completely still right next to us for over half an hour! In this time period, the storm became surface-based and developed the most insane structure I have ever seen! A wall cloud developed as well and rotated rapidly. It was the most violent motion I've seen in a wall cloud without a tornado being associated with it! It started heading towards us again and we had to book it to stay ahead of the storm and its decent hail core (if I recall correctly, recorded hail up to baseball-sized), so I finally stopped taking pictures at 5:26 PM, 38 minutes later. I never thought I'd have the opportunity to document a storm for so long in one place!
Watch the storm's transition from high-based to surface-based starting around 0:25!
Sorry about the cars. Noob mistake. Will never forget to cross the road ever again. May try to go back and edit them out at some point in the future, but no time today! More chasing in my future!
