Did you notice unusual clouds in the sky this morning?

We received several photos from viewers who asked us about the cloud formations.

The clouds are called asperitas clouds, formerly called Undulatus asperatus, a Latin name that translates to mean “agitated (or roughed) waves.” The clouds are commonly referred to as the wave clouds.

According to meteorologist Danielle Dozier, they were proposed to be a separate cloud type by the Cloud Appreciation Society in 2009.

“They appear dark and eerie and are usually seen in the morning or midday hours following thunderstorms,” said Dozier. “They are called wave clouds because of their wavy appearance.”

The clouds typically appear dark and tend to dissipate without a storm forming.

Although they can appear in Indiana, they usually form in the Plains States.
