Looking like something straight out of a Hollywood movie, dark clouds gathered swiftly in a large swirl over a rural section of Wyoming near Newcastle on Sunday evening, forming a rare weather phenomenon called a supercell. It's the most dangerous of all thunderstorms, marked by an ominous-looking vortex of air that can quickly turn into a tornado.
Stop what you're doing and check out this time-lapse video of the storm's supercell formation shot by the brave thrill-seeking stormchasers at Basehunters Chasing. They've crammed a little bit over an hour's worth of the supercell's footage into an action-packed 2 minutes.
It starts getting really nuts around the :55-second mark.
