Meteorologist @JenCarfagno of The Weather Channel said "undulatus asperatus" clouds put on the display that lit up social media:

"Undulatus asperatus translates to 'roughened waves' - Looks like an angry sea, doesn't it?" 

Science writer and meteorologist Anthony Sagliani of Accuweather said a gravity wave packet created the awesome cloud structure:

Per Wikipedia:

"Undulatus asperatus (or alternately, asperatus) is a cloud formation, proposed in 2009 as a separate cloud classification by the founder of the Cloud Appreciation Society. If successful it will be the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization."

Got my vote.

Neat science.

Cool clouds.
