It can hardly be too cold for snow to (form and) FALL, hough if it really IS very-very cold, the air usually is very dry and no snow will fall (no vapour, no condensation, no snow)
If it's very cold and snow HAS already fallen, it will "sublimate" very fast: it won't MELT (too cold for that) but it goes directly from crystalline to vapour state, and blows away.
And too: it doesn't STICK together, so a little bit of wind blows the snowdust in one corner and the road is cleared .
Oops, beeper going: have to leave.
See you tomorrow ? |
