I was here at FR when it was happening today. I know this is a long thread, but please look back at the radar signature at the time of the storm. In my whole life, I had never seen a more evident radar structure and track as this one. No hook to pinpoint it was needed. It looked like a mini-hurricane as it made it's eastward track.
From what I understand the weather forecasters on the local networks were all over the storm because they were looking at the radar similar to you in real time. The first upward spinning of water (clouds) occurred sometime after 1:00 when rotation was reported in the fast developing supercell. It touched down as an F3 about 45 minutes later and became an F5 in about 1 hour and 15 minutes from first spin. That was the track and timeline that was just shown on KFOR. Was still sleeping myself out here in Central West Texas when it was forming, so you probably know more about it then me.
