A rare tube-shaped cloud created a spectacle in northern Virginia yesterday (Sept. 16) as it crept across the sky. The U.S. National Weather Service’s Baltimore/Washington office in Sterling, Va., snapped a panoramic photo of the ominous-looking roll cloud as it moved over the area. “An outflow boundary from the showers associated with the cold front produced a very well defined roll cloud that passed over our forecast office this morning just before 7:30 am,” the NWS office said in a Facebook post. Roll clouds belong to a family of low-forming clouds known as arcus clouds. They are related to the more common, wedge-shaped shelf cloud. Shelf clouds often form on the leading edges of thunderstorms (or sometimes a cold front) as rain-cooled air ploughs under the warm, moist air that’s closer to the ground.
