Freezing rain is the name given to rain that falls when surface temperatures are below freezing. Unlike rain and snow mixed, ice pellets, or hail, freezing rain is made entirely of liquid droplets. The raindrops become supercooled while passing through a sub-freezing layer of air many hundreds of feet above the surface, and then freeze upon impact with any object they encounter. The resulting ice, called glaze, can accumulate to a thickness of several centimeters. The METAR code for freezing rain is FZRA.
A storm that produces a significant thickness of glaze ice from freezing rain is often referred to as an ice storm. Freezing rain is notorious for causing travel problems on roadways, breaking tree limbs, and downing power lines. It is also known for being extremely dangerous to aircraft since the ice can effectively 'remould' the shape of the airfoil and flight control surfaces. (See atmospheric icing.)

“If you meet a sectary, or a hostile partisan, never recognize the dividing lines; but meet on what common ground remains,if only that the sun shines, and the rain rains for both; the area will widen very fast, and ere you know it the boundary mountains, on which the eye had fastened, have melted into air.”
—Ralph Waldo Emerson (18031882)
