Water Vapor Images
estimating moisture


Darker colors indicate drier air while the brighter the shade of white, the more moisture in the air. In the image above, very dry air was present from Oklahoma into Illinois (indicated by the dark colors). Bright white plumes stretching from Missouri to South Carolina indicate the very moist air associated with thunderstorms occurring in the area.
