Storm Front Surprise

This month’s cloud is known as an arcus, or shelf cloud, which sometimes prodrudes from the front base of a Cumulonimbus storm cloud. It was spotted by Eunice Clarke over Turnberry, Ayrshire in Scotland. “It was amazing standing there,” Eunice told us, “I was taking landscape pics on a nice sunny evening, when this strong gusting wind came from nowhere. When I looked behind me, this is what I saw coming towards me.”
