Most snow comes when it's relatively warm. But there exists a variety that we Finns call "pakkaslumi" (I'm not aware of a good translation) which occurs when it's cold (anything below -10 Celsius, even -30 Celsius possible). It's very light and almost powdery (reminds me a bit of sugar, actually), and one cannot build anything out of it (it doesn't stick enough for making a moldable mass of snow).
