Mammatus are sometimes seen when unsettled weather occurs. Thunderstorms are almost always in the vicinity, sometimes in the process of decaying, but the weather need not be severe for these clouds to be reported. For mammatus to form it’s thought that downdrafts must play a role — cooler air from aloft pushes through the cloud base resulting in the pouch-like appendages.
