What Is That Cloud In The Sky?

GREENSBORO, N.C. -- It was one strange and scary looking cloud associated with a strong thunderstorm on Thursday that moved across the Piedmont Triad.

You might have even seen it in the sky. So, what was that scary looking cloud? 

That’s what many of you asked WFMY News 2 on social media.

That scary looking cloud is what’s called a Shelf Cloud. A shelf cloud represents the leading edge of strong winds in advance of a thunderstorm. The cloud itself is a low, horizontal wedge-shaped cloud associated with a thunderstorm gust front. Often you can see a rising cloud motion in the leading part of the shelf cloud while the underside often appears turbulent, boiling, and wind-torn.

Thank you for sending and sharing your shelf cloud pictures with WFMY News 2!
