I think spotter training is in the dark ages along with visual analysis of "tornadic" thunderstorms. I just talked with NWS personnel in North Carolina. I took some video of something I didn't know what it was. It looked like a meso. Looking back at it there is what I would call ribbing of the clouds high up in it. From earlier in the day that showed strong parallel movement along the rib axis. In the middle just below the "ribbing" is a cloud attached to the "meso" that increasing looks like a funnel with a well defined darker funnel shape. At the same time is a funnel shape right in the middle of the "meso" that is bigger and more persistent. Both of these funnel shaped clouds disappear after the "ribbing" disintegrates. This Meso looking cloud just happens to be at the southern edge of a dying thunderstorm. Oh there also is what appears to be a very well defined collar cloud around the "meso". I'm sorry but if it looks like a duck, quacks like a duck and lives in a pond I'm calling it a duck. Not only is the cloud located in a southern extremity, there was not really any rain to speak of and the air conditions were favorable for tornadic development as there was a tornado watch at the time. Oh the edges of the meso were fairly well defined also.
You should upload this video to YouTube so we can analyze it is as well. It sounds like a fascinating event!
