Ice storm
Or, the liquid droplets continue to fall without freezing. They pass through the cold air just above the surface. This thin layer of air cools the rain to a temperature below freezing (), but the drops themselves do not freeze. This is a phenomenon called supercooling. When the supercooled drops strike ground or anything else below  (e.g. power lines, tree branches, aircraft), a layer of ice builds up, hence "freezing rain".
