Big Billowy Mammatus 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.
Taken with an old Pentax camera.I was just amazed at these clouds..I stepped out as a bad storm had just went through and this is what I saw in the sky.. kind of eerie! I had to let a little bit of the tree top and telephone wire in pic so I'd remember which way the clouds were going.
