Wild Wyoming cloud wows weatherwatchers

A phenomenal shot of a massive cloud Sunday near Clareton, Wyo., has been making the rounds on social media today.

The photo was taken by the Basehunters storm chasers group, who are "committed to capturing the most unique and close-up tornado footage on the market," according to their Facebook page. It shows the rotating updraft of a supercell thunderstorm over eastern Wyoming, according to Weather Channel meteorologist Jon Erdman.

Supercells are the largest, strongest and longest-lasting thunderstorms. They are most common on the Great Plains.

Known as a "low-precipitation" supercell, these types of storms seldom produce heavy rain or tornadoes, though they can produce large hail, Erdman said.
