A severe thunderstorm hit Colorado on Monday, May 8, 2017, dumping hail as large as tennis balls. The storm blanketed the state in a thick layer of ice, leaving widespread damage and traffic delays. Hundreds if not thousands of vehicles and buildings were damaged. Although most of the hailstones did not exceed the size of golfballs some of them were as big as tennis balls and there are even reports of hail larger than a pool ball.

A severe thunderstorm moved over Denver shortly after 15:00 MDT and was very slow-moving, AccuWeather Meteorologist Brian Edwards said. “Since the storm was barely moving, hail piled up several inches, causing widespread travel problems in the metro area.” Air traffic was also impacted as more than 150 flights at Denver international Airport had to be delayed.
