HEBRON, Ky -- Reports started coming in around 10 a.m. of odd-looking clouds around Hebron. Then a few minutes later, there were more reports from Erlanger.

And the common theme was, "What is this?"

As always, your 9 First Warning Weather team has an answer. These are called undulatus asperatus clouds or, more simply, wave clouds. This cloud wasn't even given a name or classification until 2009, so it's newer in the weather world. 

The clouds appear dark and storm-like in the low levels of the atmosphere. What you are seeing in the clouds is the turbulent wave motion in the atmosphere. This cloud type will often form ahead of showers and storms.
