A group of stormchasers captured footage of a supercell thunderstorm developing over Wyoming last weekend.
Supercells are the least common type of thunderstorm, but they are responsible for most of the violent tornadoes in the North America. They bring extreme winds, and dump torrential rain and hailstones that are bigger than golf balls. Their spinning vortices of air can reach speeds of over 160 km/h and last for hours.
The Basehunters out of Norman, Oklahoma, created this time-lapse video from Wright to Newcastle in the northwestern part of Wyoming.
