Finally got around to uploading my June 5th footage (didn't think I had anything worthwhile!) and noticed some interesting features on what was dismissed at the time as outflow and scud. After intercepting three or four supercells and watching everything merge into a linear mess we stopped in McPherson for some grub. We headed east on Hwy 56 around 5:30 and although the storm was not TOR warned, I saw that familiar embedded shape on GRLevel3 and kept looking back west as we drove east. We saw what appeared to be a very brief (<15 seconds) and very thin rope just north of the highway, but I was the only one that didn't write it off as shapely scud (I sat on THIS BENCH for a little too long that morning). We pulled over and debated about what we saw while I set up the video cam on the tripod. LCL's were quite low and contrast wasn't great so it was hard to decipher at the time what was slowly rotating and what was scud, but looking at video now it is obvious that there was rotation with a few suspicious features. Going over the archived level 2 data, this matches up perfectly with the 22:20z-22:37z scans where there appears to be a well defined embedded supercell structure and the NROT algorithm peaks over this area at 22:37z. I have emailed the ICT office with this information but haven't heard back.
So here is the video (time lapses at the end), what do you all think?
