An imminent icing condition enunciator (10) employs an infrared sensor (22) with a focusing element (31) to receive ambient infrared energy from a surface, particularly a road surface, and the output of the sensor is processed (14) to provide an indication (86) of imminent icing to the operator of, for example, an automobile or other vehicle. The device is suitably mounted to a vehicle (51), within a mirror enclosure (52) so as to provide an unobstructed view of the roadway surface.
