Altostratus clouds are gray and usually cover the whole sky. Nimbostratus clouds are dark and produce rain or snow. Low level clouds are found less than 7,000 feet.

Shelf cloud: A low, horizontal, sometimes wedge-shaped cloud associated with the leading edge of a thunderstorm. Although these clouds appear ominous, shelf clouds normally do not produce tornadoes.

Today, 10 basic cloud forms are recognized, all of which owe a debt to Howard's nomenclature. Some are low-level clouds that exist below 6,500 feet, such as cumulus, stratus, and stratocumulus.

As the air rises, it cools, condenses and produces clouds and precipitation. This quick rising motion often leads to showers and storms, and occasionally, severe thunderstorms.

Stratiform is a different type of precipitation. It can be your classic, gloomy day with nimbostratus clouds that bring widespread, lingering rain.

Ominously dark cumulonimbus clouds indicate an approaching cold front, while nimbostratus clouds (flat, gray, overcast) predict an approaching warm front and bring drizzle or steady all-day rain.

Low fog-like stratus clouds or ragged gray nimbostratus clouds will hide the cosmic show. Cotton ball-like cumulus clouds may just drift by, obscuring parts of the two-and-a-half hour event.

Nimbostratus: Dark gray cloud layer diffused by falling rain or snow. It is thick enough to blot out the sun. Other low, ragged clouds often occur beneath this cloud and sometimes merge with its ...
