If ever you felt uncertain about the sheer power of thunderstorms, this gorgeous video of a gigantic forming supercell over Wyoming should convince you otherwise.

Supercells are severe thunderstorm, notable for both their rotating winds and for the long duration they can play out over. Though this particular one did not touch down to form a tornado, it's easy, as you watch the clouds spin rapidly overhead, to see just why supercells often do end in tornadoes, or at the very least extremely damaging storms.
The timelapse of the storm as it formed over Wyoming yesterday, which you can see below, was made by Basehunter Chasing, who also tweeted the image of the supercell above.
