Cumulus humilis, also known as fair weather clouds are the smallest convective clouds and the first stage in development of convective clouds. They typically form at 500 to 3000 m altitude and have limited vertical development. Cumulus humilis rarely produce any type of precipitation. You can spot these clouds on many summer days; they often form in the late morning or early afternoon as the ground heats up. If they are present early in the day, they may be a sign of an unstable atmosphere.
