Wakita cell - Just RFD?

[Nick Nolte]

I'm still a bit hazy on the details of this. The photos I grabbed were about quarter mile north of OK-11 on OK-11a (road to Wakita), I thought I was looking due west (perpendicular to the N-S highway I was on) and that was the MV in this photo that I took: http://www.whitedashes.com/mobile/IMG_0839_1068x712.jpg
It would be north of 11 already at that point right? I watched for a while before that photo, and I just thought it was always north of 11. Not sure though.

But all the accounts talk about the MV crossing 11...are they talking about mainline 11 or 11a? Even that video that was on TWC had it crossing the road (which I assume was 11?) Add on top of that the graphic from OUN showing the tracks, which doesn't even show it down before 11a on the graphic.

EDIT: The camera timestamp on that photo I linked is a few seconds after 3:40pm

My camera timestamps show the storm Wedging out just east of HW81 north of Medford. It's still multivortex at 20:57, is rainwrapped by 20:58 and at 21:01 due north of MEdford, my images show the back half of the storm is fully condensed and it appears to have transitioned to a classic if rain wrapped wedge.

The heavy rain at the leading edge of the meso obscured my view between 20:58 and 21:01 so I can't be more precise than that, but I hope that helps.

If I remember correctly, the 20:58 Vance radar showed the mean wrapped up hook, and the 21:03 was the first radar scan to show the donut hole...

I haven't seen any videos with this part of the convoy at a distance where you can see clearly what is happening.

I was a few miles back from the video you posted. I hadn't planned on uploading it, but it may help a little on this discussion. It's only 480p and not great contrast, so I would imagine there may be some more detailed video between where I was and the video you posted. I was a little ways west of the 11A road to Wakita when the RFD punch in the video you posted hit. It was some amazing motion. This was sped up to 4x to see the motion even better, but also to negate a bit of camera bounce from my dash mount.

Davies' blog confirms everything I thought was going on, he is the man! This image explains everything.

The reason I've been curious about this is because I filmed a tornado that bounced around 6 miles East of Wakita Hwy, though this tornado was far from a Barrel or wedge, thus I'm not wondering if there wasn't a second circulation behind the main one...

Yeah I filmed that same deal as I went east and can say it was way way behind the main area by then. And way way nw of that I swear I was seeing a "spout" type deal on the ground, just a short condensed landspout type vortex stuck in one spot way way behind things.

For more time reference, my photo (http://www.whitedashes.com/mobile/IMG_0843_1068x712.jpg) which was taken E of the storm on 11a (just N of 11) and taken at 3:41pm corresponds to the video from the west shot by Scott Weberpal here (http://convectiveaddiction.com/2010/05/14/entire-may-10-wakita-videos-now-online-full-1080p/) at the 2:58 mark in the first video.

Here is some video I shot of the tornado from Highway 81 just north of Medford, OK. To me it looks like it takes on a wedge form with multiple suction vortices rotating around. I am a novice when it comes to video (and chasing) so the video does not show everything I saw. I spent the first minute or so in awe just staring before I came to my senses and started taping. Shortly after I started taping it started becoming rain wrapped.

Robert - thanks for starting a very interesting thread.

I'm not sure how helpful this will be, but here's a bit of my video of the Wakita tornado just before and during its most pronounced multivortex stage. I shot this from just north of SR 11 on Trenton Road, about one mile east of the tree line. As others have noted, I too was struck (and alarmed) by the apparent southerly movement of the main circulation back across SR 11.
