Strong thunderstorms moved close to the office the evening of August 20, producing some mammatus clouds. Mammatus clouds indicate sinking air and are usually found on the anvil portions of thunderstorms (cumulonimbus clouds). They are sometimes more pronounced during and after a strong thunderstorm. In a thunderstorm, precipitation is carried upward by an updraft. Some of this precipitation (ice crystals and water droplets) spreads out, and forms the anvil of a thunderstorm. The precipitation particles are sometimes heavier than the surrounding air, and begin to sink. This sinking and the associated evaporation cause the "pouch-like" mammatus clouds. NWS Louisville
