Roll Cloud Over Wisconsin
This rare roll cloud over Wisconsin is a type of arcus cloud. It forms when a downdraft from an advancing storm front causes moist, warm air to rise and cool. When this happens uniformly along an extended front, a roll cloud can appear, sometimes with air circulating along its horizontal axis.
