The bacterium Pseudomonas syringae, for example, has a protein which binds water molecules together in a pattern that mimics the lattice pattern of molecules that forms in ice.
By doing so it facilitates ice formation at warmer temperatures than would otherwise be the case. The ice then either melts on the way down to form rain or falls as snow or hail.
