I don't know much about the weather, only that lately here in the Arklatex it's just been hot. No rain, no relief. So I guess that's why I gravitated to this video of some creepy looking clouds. Seriously they look straight out of a disaster movie. Don't worry though I've got the science behind the clouds.

Its a shelf cloud! Quite an awesome looking one as well. Pretty much what is happening is the cooler air is lifting the warmer air, water condensing happens, and the cloud seems to "roll" with the different winds involved. This is usually found in the storms downdraft. I bet this was quite the windy, nasty storm.
