Cumulus Humilis Clouds

Cumulus clouds can be associated with good or bad weather. Cumulus humilis clouds are common in the summer and are associated with fair weather. They are usually widely spaced in the sky, have a flat base and rounded tops, and sometimes they look like sheep grazing in a pasture.

Cumulus congestus clouds are much larger, look like caulilower, and are associated with bad weather.
