The short answer is "Snow Pellets." But others have come up with their own affectionate name for this strange precipitation.
Meteorologist Colin Hackman said to me early this afternoon in brief passing as he headed out to get video, "It looks like nerds."He also reminds me that the Inuits have over 100 different words for ice and snow. It's not something we have to think about often.It's been "Nerding" for about an hour. Some other suggestions from emails and our facebook friends?
Dipping dots, skittles, flea-sized snowballs, snow stars, sneet (snow-sleet), and snail (snow-hail)
