Storm chase video of a tornado near Tonkawa, Oklahoma on 13 May 2009. I got some video of the Anadarko tornado on this day as well, but it was after dark and the *possible* tornado was only lit up by lightning and power flashes (I believe our stovepipe-shaped cloud was the tornado, though, as it was in the right place at the right time that it was being reported, and it sure looked like a tornado). www.greenskychaser.com
