Freezing Rain MET

Freezing rain forms when liquid water (in the form of rain, so falling from clouds with a temperature above 0 degrees) falls into air which is below 0 degrees. The water cools to below freezing, making it a large supercooled water droplet. This situation with warmer air aloft and cooler air below is most commonly found at warm fronts and warm occlusions. As the rain is a large supercooled water droplet, it forms clear ice when it hits something.
