Severe T-Storm Gustnado? Options

[southernskiing]

Yesterday evening we had a Severe T-Storm Warning go out on a cell that passed to out northeast. It was moving southeast. The lowlevel outflow was churning with the shear in the mid/upper levels and made for some impressive looking clouds. We're in the mountains and don't see weather like this often. I shot this video with a Gopro and sped it up to see the shear better, you also see some weak rotation caused by the shear. Is this how a gustnado forms (although this was weak)?

Pay attention to the first 3-4 seconds in the video, it looked like scud clouds rising from ground level. They were going vertical.
