Steam rises from frosted rooftops along Elzer Drive in Scotts Valley on Monday as the mercury in thermometers continued to drop. The National Weather Service listed local overnight temperatures in the low 30s, but actually above freezing. Why the frost on rooftops and ice on cars? National Weather Service Science Officer Warren Blier explains, that the temperature of the air at the level of the ground needs to be 32 to freeze, but official temperatures are taken from instruments located in instrument shelters located 6 feet off of the ground. Even if the official temperatures are higher than freezing, temperatures on the ground could be well below freezing. Also, surfaces that emit heat, such as metal car roofs, could get colder than the ambient temperature. The official forecast calls for a slight warming trend and rain probable on Thursday.
