Had called it a night and were heading towards Sioux Falls when this thing really took off -- simply didn't pay attention to the radar for a bit, and missed it.
A person that didn't miss this storm was my brother, who had a wedding to attend in Sibley Iowa.
Get a call from him while in Sioux Falls stating that sirens are going off in his town. Check the radar... sure enough, nice hook, and heading what looked to be west of Sibley Iowa. Told him if he takes a peak west and north, he should be able to see it. Sure enough... few minutes later he calls telling me he's got a tornado in between lightning flashes. Doesn't think it looks too big. (turns out this was only because it was partially rain wrapped -- I saw the video and he had a good sized tornado) Bails on it as it seems to be moving towards him and heads back to the hotel only a few blocks back east.
The tornado just barely missed his location. In retrospect, feel a bit stupid suggesting he take a peak at the storm -- hadn't had radar up long, didn't know he'd be looking at a tornado as it was or neared EF4 strength. At least he knew not to try anything if he couldn't see it.
Later on, after the storm had cleared them... he went out again. Another tornado snaking its way SE away from them. They could see clear skies and stars... with a lightning lit tornado. Amazing sight I'm told.
I'll get some video captures from him soon, hopefully he'll get the video up sometime here.
Along with Andy... the only person I know that has captured good footage of it. (and perhaps the only footage of what would seem to be the EF4 strength phase -- though I need to figure out his exact time of video capture)
