Wow. I've seen several of those before, but some were new, and all were definately powerful. I think my favorite was the tornado with the shed in the foreground, 5th from the bottom.
We had amazing sheet lightning last night, transfixed me for at least 20 minutes when I went to close the ladies in the coop. Wish I could have gotten pictures.
The one with the shed in the foreground though, sure seems to have been "Shopped". With a tornado in that proximity, winds should have been all inflow (towards the tornado). Also, the wheat around the shed does not seem to have been influenced by the wind that is destroying the shed.
