On June 21, citizens were in for a meteorological treat when a shelf cloud rolled over Williamsburg County. According to the National Weather Service, shelf clouds appear on the front side of thunderstorm cells just ahead of the downdraft. They can extend for 10 to 50+ miles and have cloud fragments that briefly resemble funnel clouds. Shelf clouds differ from wall clouds. A wall cloud appears on backside of potentially tornadic thunderstorm and will change their shape, size and color with time. The width is typically half a mile to two miles. Wall clouds also can become fragmented or look like a beer barrel.
