Newly-named cloud makes eerie appearance over Great Lakes

Strange clouds appeared above Michigan's Thumb June 13, 2017. These clouds have been given their own classification in the past 10 years. This type of cloud is the first cloud type to get a new classification since the 1950s.
The wavy clouds that appeared over Michigan's Thumb June 13, 2017 are now called asperatus clouds. That cloud classification didn't even exist until the World Meteorological Organization recognized them in the International Cloud Atlas this past spring.
Asperatus means rough. If you flew through air where these clouds were located, you would know why we call them rough. The clouds are formed in the leftover undulating atmosphere, after a complex of severe thunderstorms rolls through. These clouds were formed Tuesday morning, June 13, 2017, after severe storms moved through northern Lower Michigan Monday night.
