Graupel is a snowflake that forms in a cloud, and hits super-cooled water droplets that are below freezing, but have not turned to ice. That's because some foreign body, such as a grain of sand or sea salt, is keeping the ice from forming.
When it finally falls, it hits the ground in the form of white pellets.
David Murphy takes a closer look and has more photos of graupel in the above video.
Here are some more photos of this apparent graupel:
