There will also be a few somewhat big changes coming to the site in a week or so. Nothing drastic I suppose, but it's something anyway.
This is right as the initial EF2 tornado wound down, and the storm went haywire and the massive EF4 tornado began to spin up. A small funnel cloud is visible amongst the ragged violently rotating storm base.
There may be more than one tornado on-going at the moment that this photo was taken, hidden behind the rain. At this point I had missed an incredible tornado, and also done damage to my vehicle by hitting a pheasant at 65 mph, so I was in damage control mode and taking the path of least resistance by hanging back and shooting structure photos of the storm.
On the way back to the motel that I had reserved in Sioux City, SD I kept looking up at these mammatus near Aberdeen, SD, in a sour mood not wanting to make any more stops before eventually convincing myself that I would regret not popping off at least a couple of photos.
