Residents across southern Ontario took to Twitter to share photos of what appeared to be hail in their area on Saturday.
is precipitation that forms when supercooled droplets of water are collected and freeze on a falling snowflake, forming a 2–5 mm (0.079–0.197 in) ball of rime. The term graupel comes from the German language. Graupel is distinct from hail, small hail and ice pellets: the World Meteorological Organization defines small hail as snow pellets encapsulated by ice, a precipitation halfway between graupel and hail. The METAR code for graupel is GS.
