Mediocris

Definition

A species of cumulus of moderate vertical extent, with somewhat bulging tops, roughly as tall as it is wide. It lies between cumulus humilis and cumulus congestus in the convective sequence.

Field note

Mediocris is the transition point to watch. If the tops keep bulging and the cloud keeps growing taller through the afternoon, the sequence is heading for congestus and possibly a shower.
