Frozen vapour from the atmosphere. A snow crystal is an ice crystal up to 5 mm across, variously shaped as a prism, plate, star, or needle. Snow crystals fall from stratiform clouds when the low-level air is several degrees below freezing point and the air above is colder. When the low-level air is near 0 °C, snow crystals aggregate to form snowflakes.
