Winter left a few late memories Wednesday when an icy substance known as “graupel” fell across portions of Western Maryland, according to the National Weather Service.
Graupel is formed when snow starts to evaporate when it is falling, but then picks up moisture as it nears the ground, said Stephen Konarik, a meteorologist with the National Weather Service in Sterling, Va.
When graupel hits the ground, it looks like a pellet. But unlike sleet, which is clear, graupel is white, Konarik said.
The substance was falling throughout regions north and west of Washington, D.C., including mountainous areas close to Camp David in Frederick County, he said.
