appearance. These clouds usually cover the entire sky and are indicative of
precipitation in the future. These clouds will also produce a "halo effect" around the sun and moon!
usually telling us that snow or rain is coming. With these clouds people will often see virga as well; virga is precipitation that evaporates before it reaches the ground.
