Cloud Formations

Cumulonimbus: Can cause lightning, thunder, hail, strong rains, strong winds, and tornadoeshttp://markosun.wordpress.com/2012/07/13/riding-under-a-parachute-through-a-severe-thunderstorm/cumulonimbus/

Cirrus: The appearance of cirrus clouds usually indicates that a change in weather will occur within 24 hours. They predict fair weather.http://en.wikipedia.org/wiki/Cirrus_cloud

Different types of clouds bring different types of weather!

Cloud Formations

Cirro-Stratus: usually come 12-24 hours before a rain or snow storm.http://usatoday30.usatoday.com/weather/wcirrus.htm

Stratocumulus: Precipitation rarely occurs with Stratocumulus clouds, however, in frontal weather they may turn to Nimbostratus.http://www.windows2universe.org/earth/Atmosphere/clouds/stratocumulus.html

Stratus: Light mist or drizzle is sometimes associated with Stratus clouds.http://weather.ou.edu/~smglenn/clouds.html

Cumulus: These small, lumpy clouds are low "fair weather" clouds.http://commons.wikimedia.org/wiki/File:Cumulus_clouds_in_fair_weather.jpeg

Altostratus: Usually forms ahead of storms with continuous rain or snow.http://mariaruthbooks.blogspot.com/2011/02/cloud-of-week-5-altostratus-undulatus.html
