Usually, when the sun goes down, the temperature falls. Once in a great while, a warm front comes through and the temperature will rise during the evening or overnight. Once in a while, on a calm clear night, the wind will come up and bring down some warmer air from above the surface or a cloud layer moves in the temperature fall will stop and maybe go up a few degrees.
