I recently visited with Dr. Murry Decoteau and Sam Roberts, who had once again successfully “cleaned out” Bill Davis and Mim Thompson in a gin-rummy game. Murry inquired if frost could form even when the temperature was not 32 degrees. Some of the absolutes of frost forming, in this scenario, include a clear night and calm winds. Even though it won’t be widespread, air temperatures slightly above 32 degrees but no higher than 34 degrees can generate frost. Frost is water vapor that has condensed as ice onto a surface. Blades of grass lose energy at night by emitting radiation, and due to this energy loss, they become more accessible to crystallization. If the deposited surface is colder than the surrounding air, “spicules” of ice grow from the surface.
