A snow tornado. Blizzard conditions with tornado warnings seemingly common in the Erie, PA area.

The weather terrorists are calling for a snow and a tornado, a snownado!

snownado 

A less powerful tornado, made of snow, with the same amount of force as a sand storm.

1) I'd prefer getting caught in a snownado over getting caught in a sand storm ANY day! Because snow getting in your eyes is basically like putting in eye drops, and sand, well, isn't.
2) I got caught in a snownado right over there. Luckily I made it to safety.
