What are Green Clouds?

Green Clouds are often associated with severe weather and are likely when thunderstorms with heavy rain are strongly illuminated from behind by reddish sunlight, such as at sunset. They may also form when the clouds are illuminated by light reflected off green vegetation, such as large corn fields or a heavily wooded forest.

In the Great Plains region of the U.S., green clouds are associated with storms that are likely to produce tornadoes or large hail, however, it is the presence of very high water content that causes the coloration, not hail itself.
