"Breast-clouds"? Mammatus, of Mammary Clouds!

Mammatus Clouds, or "breast-clouds", are fascinating formations in the sky, made mostly from the cumulus cloud base. Although they are not a sign that a tornado is about to form, they often accompany tornado-producing storms, or even may be direct byproduct of tornado activity - an aftermath of severe thunderstorms.

Check out Jorn Olsen for some weird mammatus clouds shots.

Mammatus clouds do not form on the cloud base, rather the anvil of a thunderstorm. Also, while they accompany severe weather, they most certainly are not dependent or a byproduct of tornadic activity. They are pockets of descending air brought on by the fact there is a large amount of air being drawn aloft by the updraft of the thunderstorm.
