Clouds of the Day - Friday, December 25, 2020

This morning dawned with clear skies but a band of stratocumulus clouds crossed the area late morning into the early afternoon. The clouds formed in a region of warm advection (relatively warmer air aloft moving over a layer of cold air in contact with the surface. Stratocumulus form in a layer of stable air that includes weak upward motion caused by warmer air aloft being lifted weakly slides upward over a lower layer of cold air.
