A supercell (also known as a rotating thunderstorm) is a type of thunderstorm that forms in the presence of rotating updraft. Overall, supercells are less common than a classic run-of-the-mill thunderstorm, which is fortunate since supercells have the potential of being very severe. They are most commonly identified by their ominous rotating structure and usually occur in arid climates (such as the Great Plains of the United States), but supercells can form anywhere in the world under the right conditions. On Sunday, storm chasers caught a supercell thunderstorm as it was taking shape in Wyoming. It is absolutely spectacular. To see the most amazing parts, jump ahead to 0:44. That's when the cell really starts to form. You will want to watch until the end. It leaves almost as quickly as it forms.
