How does freezing rain form?

Freezing rain forms when liquid raindrops reach surfaces that are below freezing and freeze on contact, creating a glaze of ice. This happens because the air near the ground is cold enough to turn the raindrops into ice upon impact, but they stay liquid while falling through a shallow subfreezing layer near the surface after melting from snow higher up in the atmosphere. The rain begins as snow or ice aloft, melts into rain in a warm layer, then passes through a thin cold layer near the surface, remaining supercooled until it hits objects that are at or below 0°C. If the surface layer were deep and cold enough, the drops would refreeze before reaching the ground, producing sleet instead.
