As if January 2018’s record cold, snow fall, storm surge, and winter winds are not dangerous enough, the “bomb cyclone” of Winter Storm Grayson generated intense levels of lightning along the East Coast. The density of winter lightning storms, also known as “thundersnow”. has probably been underestimated in the past because snow muffles the sound of thunder and limits the visibility of lightning. New techniques for monitoring lightning strikes are, however, reveal the full extent of thundersnows that occur during winter.
By the way, a viral video shows a weather reporter, broadcasting out-of-doors, dancing with excitement after witnessing thundersnows. We can understand the thrill this professional meterologist experienced due to this display of nature’s power, but caution that he was endangering himself and his camera crew. Summer or winter, remember, When Thunder Roars – Go Indoors.
