WYOMING — Check out this amazing time-lapse video of a supercell storm forming over Wyoming.

Storm chasers from Basehunters spotted the storm forming between Wright and Newcastle.

The weather system produced heavy rains and hailstones the size of baseballs.

NOAA has this definition of a supercell thunderstorm:

Supercell thunderstorms are a special kind of single cell thunderstorm that can persist for many hours.

They are responsible for nearly all of the significant tornadoes produced in the U.S. and for most of the hailstones larger than golf ball size. Supercells are also known to produce extreme winds and flash flooding.

Supercells are highly organized storms characterized updrafts that can attain speeds over 100 miles per hour, able to produce extremely large hail and strong and/or violent tornadoes, downdrafts that can produce damaging outflow winds in excess of 100 mph – all of which pose a high threat to life and property.

The majority of supercells fall in the “classic” category. These have large, flat updraft bases, generally has a wall cloud with it, striations or banding can been seen around the periphery of the updraft, heavy precipitation falls adjacent to the updraft with large hail likely, and have the potential for strong, long-lived tornadoes.
