Summary Authors: Jens Hackmann; Jim Foster
The panorama featured above shows a sinister-looking shelf cloud as it approached the town of Bad Mergentheim, in southern Germany on June 6, 2010. Shelf clouds are attached to the parent thunderstorm and are positioned at its leading edge. They typically form when cool air associated with a thunderstorm's downdraft advances into the warm, humid air feeding the storm. Though they generally don't presage the formation of tornadoes, their winds can at times be severe.
