Tornado in Grand Forks, ND

I saw my first tornado today. Amazing sight! Actually I saw three tornadoes, but I only managed to get two of them on video.
I missed the first one (right before min. 1:48 in my video) Because I was driving. But found some pictures of it on Flickr and a video of it on YouTube.

Jump to Min: 2:30 to see two of them at once.
