Press release on the twisters here, with some really nice images - including an amination of the telltale flying and the solar panels flapping! There is also one of some rather dramatic cloud movement that I didn't post because I thought it looked "wrong".
There are estimates of size and distance in the press release.
Er, I got the twister times wrong by 10 hours. I really didn't understand HOW a twister could form at 2AM but that was how I misread the times - so that's what it HAD to be!
Say, does that mean NO ONE is checking my work? Remember - you don't have to take anybody's word as gospil -- you can verify it all yourself.
