Graupel, also known as soft hail, corn snow, hominy snow, or snow pellets, is a type of precipitation that forms when supercooled water droplets freeze onto snowflakes, creating small, opaque pellets of ice. Graupel typically has a diameter ranging from 2 to 5 millimeters (0.08–0.20 in) and is characterized by its soft, granular texture. It looks like tiny, broken up, foam packing peanuts.
