We haven't had a thunderstorm in 7 months. It's not quite snow and not quite rain. Graupel (/ˈɡraʊpəl/; German: [ˈɡʁaʊpl̩]), also called soft hail, hominy snow, or snow pellets, is precipitation that forms when supercooled water droplets are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime. Graupel is distinct from hail and ice pellets. Hail is common in thunderstorms, while graupel typically falls in winter storms, and in convective showers. The METAR code for graupel is GS.
