Howard believed that all clouds belonged to three distinct groups: cumulus, stratus and cirrus. He added a fourth category: nimbus, to describe a cloud “in the act of condensation into rain, hail or snow”. It is by observing how clouds change color and shape that weather can be predicted, and as long as the first three types of cloud keep their normal shape there won’t be any rain.
