I captured this photo today while out for a drive. I had never seen a cloud like this one. This dark grey band was all across the sky, as far as I could see. We are suppose to get rain later. I emailed our local meteorologist to find out what the technical name for the cloud was. She responded and said it looked like a shelf cloud. A shelf cloud is a low-hanging, well defined, wedge shaped formation that occurs along the leading edge of a gust front in a thunderstorm. Shelf clouds most often form just ahead of intense lines of thunderstorms.
This makes complete sense due to the weather forecast of rain. Just sharing something different! Remember to always look up when you are outside. You never know what you might see.
