A US storm chaser captured this stunning time lapse clip of a supercell thunderstorm in Kansas. <br /><br />"The storm was tornado-warned at the time, and a cone-shaped funnel can be seen dropping halfway to the ground in the video," said Sarah Kassabian who filmed the stunning footage near the town of Sublette on May 21st. <br /><br />"This was one of the most photogenic storms I’ve ever seen as a chaser, and is a textbook example of a supercell thunderstorm," she added.<br /><br />A supercell is a thunderstorm which has a deep, rotating updraft.<br /><br />They are also sometimes referred to as rotating thunderstorms.<br /><br />According to Kasabian, she did some standard, minor colour correction on the clip but it was otherwise unaltered.
