Take a look at a viral, time-lapse video of a supercell spotted in northeast Wyoming near Clareton Sunday by Basehunters Chasers:
"These low precipitation supercells are usually found in the Plains or northern Rockies as they form along a boundary dividing dry air to the west and more moist air to the east," AccuWeather.com Meteorolgist Brian Edwards said. "They generally do not occur east of the Mississippi River."
These storms produce little rainfall but can produce large hail or even a tornado, he said.
Due to the little rainfall, the storm's rotation is viewed more easily.
"The storm is rotating like a normal supercell thunderstorm but because there is little precipitation, you get a much clearer view of the cloud structure," he said, adding in the wide expanse of the Plains, precipitation normally obstructs the view.
The next day, Monday, storm chasers captured yet another low precipitation supercell.
