Drive through British Columbia in the winter, west to east from Vancouver. Vancouver is always well above freezing, the BC interior well below. You will witness all manner of snow conditions very quickly as you gain altitude. Somewhere between coastal rain and the dry snow of the interior you will hit peak-snowflake. Asymmetric 2-inch wide snow things on your windscreen is unusual but not abnormal. When standing in it you can almost see them knock into each other to become bigger. As you drive higher it will quickly tapper off into smaller flakes, as the winds get faster and the air drier. But those fat flakes are always a bad sign, an indication that the road will soon close for avalanche mitigation work: the army blasting the mountains with artillery.
