Rare, menacing roll cloud moves across northern Virginia

Roll cloud viewed from South Riding (Michael Duncan via Facebook)

On the leading edge of a cold front gliding through the D.C. metro region this morning, a scary-looking tube-shaped cloud stretched across the skies in northern Virginia. It ended up signaling mostly benign weather, in the form of some showers that followed its passage.

This cloud type is known as a roll cloud or arcus cloud.
