Clouds are a big part of weather, of course, and Chapter 6 is all about clouds. The extent of cloudiness has a lot to do with how the day feels, and the forecaster can use a variety of words to describe this big feature of weather. The National Weather Service uses these terms to describe the extent of cloud coverage of the sky.

 When the sky will be free of all cloudiness or less than one-tenth cloudy, forecasters describe it as clear or sunny.

 At three-tenths to six-tenths, the sky is partly cloudy or partly sunny or scattered with clouds.

 At seven-tenths to eight-tenths, the sky is mostly cloudy or cloudiness is broken.

 At nine-tenths to the whole shebang, it’s just plain cloudy or overcast.
