freezing rain 

Freezing rain occurs when the tempurature in the cloud and directly below the cloud are above freezing (32 degrees F), and the ground or surfaces that the rain hits are below 32 degrees. The result is big enough to shut the Washington DC metro area down for a few days.

We had freezing rain last night, so they cancelled school for a week.
