That's what is known as sleet. It where the air is warmer above and as the rain falls it hits colder air and freezes. That stuff sucks to drive on.
Snow droplets was incorrect. I meant snow pellets. Here is the definition for those like me who are not familiar with this type of snow. I agree with you brandonsdad, snow pellets does seem like sleet with one exception. The snow pellets in our yard were frozen white spheres. :-/
GRAUPE (also called soft hail or SNOW PELLETS)[1] refers to 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. Strictly speaking, graupel is not the same as hail or ice pellets, although it is sometimes referred to as small hail. However, the World Meteorological Organization defines small hail as snow pellets encapsulated by ice, a precipitation halfway between graupel and hail.[2]
The term graupel is the German word for the described meteorological phenomenon.[3] Its METAR code is GS.
SLEET refers to two distinct forms of precipitation:
Rain and snow mixed, snow that partially melts as it falls (UK, Ireland, Australia and Canada).
Ice pellets, one of three forms of precipitation in a US-style "wintry mix", the other two being snow and freezing rain (US).
