What are the kinds of precipitation?
You want all 13? Here are the classics: Rain, Sleet, Snow, Hail, and Mixed. If you need the ones only a Meteorologist would love, then you have Snow Pellets, Snow Grains, Drizzle, Freezing Drizzle, Freezing Rain, Freezing Fog, Ice Crystals and good ol' Graupel (which would be a cool band name)!
Tip of the hat to METAR. Cheers!
