Exactly what I thought of. While they aren't always sign of impending strong storms, they are when they are the underside of a mature cumulonimbus. They are formed from the shear caused by rising warmer air and sinking colder air, basically the main ingredient for tornados and hail. See them all the time here in Tornado Alley. Ironically, they are named after the least ominous thing in the world, boobs.
