Cirrus Shoreline

Resembling waves splashing against a shoreline, cirrus fibratus clouds dominate the southern sky around 3:30 PM, Sunday, January 8, 2012. This image looks past Brentwood Drive in Cedar Rapids, Iowa at the eastern border of Bowman Woods Park. Fibratus clouds exist at 16,500 feet or higher and form when there is moisture at high levels colder than freezing.
