just great. so now we're going to have tornadoes that are upside down.

edit:

yikes, i just noticed that the line that those clouds are sitting on is right near where the tornado came through. it might have just been a bit north of that, but not by far.

Those are cool. We had a thread on clouds a few years ago, some were pretty scary. I think the lenticular coulds 6 of 7 is pretty scary.

Thanks for the link!
