It would be awesome to see the whole footage, I also googled for it but didn't find anything. Mike H, where did you get it and is there a chance to see it?
There is another segment from some spotters very close to it from the west side. I think their segment was just before the farmer's. It was a pretty violent wedge with this crazy white meso from hell surrounding it. Even the back side of the meso showed this amazing bowl shape right into the tornado. Towards the end of this part that white meso is almost on the ground. It is just sick.
You probably meant this video; http://www.youtube.com/watch?v=WzL5GG34X4I. That is just insane video and definatelly one of the most impressive videos I've ever seen, just look for those few seconds part that starts at 1:35!
My SDS got a slgt improvement again, I guess it would be better not to watch such videos, lol.

That setup would be sweet if it was May.
I'm guessing it could still be sweet. The last couple gfs runs seem to be much kinder on the gulf. I hope it slows some and backs west a bit. I plan on having a good drive south to get to the real dews. I don't want to make that drive if it means treesville.
I am not sure what "cloud tags" are, but if you look at the video, you can see that they have rotation in them, unless that's an optical illusion. Then following that a larger, more substantial tornado-like vortex emerges in the place of the small four vortical bands. It's hard to imagine that there wouldn't be rotation in the small scale structures in such a strongly rotational environment. Also, there are a few other clear instances of small-scale vortices elsewhere in that video, which I hope others are also seeing. Anyway, I'm not sure I see the benign, nonrotational character of the bands in question, nor would one expect such behavior in a local environment of extreme vorticity. Can you provide more evidence to support your hypothesis? Edit: I should mention I have an open mind on it, but I'm having a hard time not seeing small scale vortices. Also, what physical mechanism would lead to such banding (alternating cloud tubes?) Vortex sheet breakdown is one possibility, or some kind of vortex instability??
The long range models definitely have my attention too. The 00Z Euro and 12Z GFS agree remarkably on the position of this upper trough at 00Z Saturday. The GFS then ejects it negative tilt into the OH Valley by 00Z Sunday... with 50s Td's and 500-1000j/kg CAPE due to the cold mid-level system. A pretty nice forecast for February. How much snow is on the ground in IL/IN now? The western gulf will have a few days to slowly modify, too.. starting Monday with the approach of the first longwave trough. Of course, the devil's in the details, and this will all undoubtedly change. I'm just loving the pattern change. Let the snow eating commence.
