This is just for the historical evidence value of the observation. On Thursday evening, November 13th 2008, John Sauder (meteorologist at CBC Manitoba) claimed to have made up the word "snizzle" for mixed drizzle and snow. "Made up" in the sense of it not being an official meteorological term. But he took personal responsiblity for it.
I mention this only in case "my very good friend" Katherine Barber (editor-in-chief of the Canadian Oxford Dictionary) is paying attention. ;-)
