During
severe weather outbreaks, conditions can change rapidly and the weather can
turn volatile quickly. It is crucial to follow severe weather and
tornado-related watches and warnings during episodes of severe storms. Keeping
a weather radio nearby, with extra batteries handy, is a must. If you are out
on the open road, staying tuned to severe weather alerts and being able to read
the clouds for severe weather can help save your life. This is the final in a
series of ominous-looking clouds we presented this week.

An abundance of heat
in the atmosphere is needed to produce enough energy for the dramatic, rolling
formations of asperatus clouds. Another factor is the interaction of very moist
air (often on the fringes of thunderstorm complexes) with very dry air. The
darkness of the clouds is likely due to the large amount of water vapor. Asperatus clouds are not necessarily
accompanied by stormy weather. In fact, they have often been observed without
the development of thunderstorms.
