Original article by Twisted Sifter:
In this dramatic capture by Ryan Shepard, we see a supercell thunderstorm never Ovid, Colorado on 28 May 2013.
A supercell is a thunderstorm that is characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local climate up to 32 kilometres (20 mi) away.
