Weather geeks, unite! This video is so cool!

I'm a self-admitted weather geek, nerd, whatever you want to call it. My favorite meteorological phenomenons are tornadoes, but I'm fascinated by ALL forms of weather. Growing up in the Midwest, I've seen these clouds many times and wondered what they are. They're called "undulatus asperatus" clouds, or "agitated waves" clouds. This is a time-lapse video from last summer in Nebraska, and I thought it was pretty nifty!
