Freezing rain is liquid water at zero degrees Celsius or lower. In nature, a specific set of conditions can cause freezing rain, which results in fast ice accretion. Freezing rain creates glaze ice.
Water can remain liquid even at subzero temperature when it travels through cold air, but does not have enough time to freeze into ice pellets. Freezing rain happens when frozen raindrops pass through a warm layer of air. This causes the drops to melt. Then the drops need to go again through freezing air, where their temperature falls below freezing, but they remain liquid. Freezing rain happens only in temperatures, where the droplets can unfreeze during their fall. It freezes upon contact with a process known as nucleation.
