Cool Clouds

If you stepped outside this evening, you may have seen some "waves" in the sky. They were very translucent, but were very distinct. We don't see these that often, but I believe they are cirrostratus undulatus clouds. What was so cool about these were that they covered a HUGE chunk of the sky! Here's another picture from one of my Twitter friends: http://twitpic.com/905nq

I thought you might find these interesting. Have a great night!
