CEDAR RAPIDS - Spectacular clouds floated over portions of Eastern Iowa Tuesday.  Though not severe weather, the rolling wisps sparked numerous calls and emails into the TV9 Newsroom.  Here's an official description of the clouds from KCRG TV9's First Alert Storm Team Meteorologist Joe Winters: 

Wave clouds form in a thin layer of the atmosphere where the temperature doesn't decrease very much with height or even increases with height. Any disturbance in this layer can cause waves of air to move along it, like water waves in a pond. If the layer happens to be humid enough, then where the air is flowing up a crest of the wave. This leads to the wave structures as we saw this morning.
