Fact or Fiction?: If the Sky Is Green, Run for Cover—A Tornado Is Coming
Hang on Dorothy, you may be in for a rough ride when trying to predict cyclones by the color of the sky

GREEN TWISTER: The sky can appear green during any severe storm, not just those that produce cyclones.
If the sky turns green during a thunderstorm, gather up your pets and other loved ones and head for the cellar, a twister is on the way. So goes the
common wisdom in much of the central U.S.—and other tornado-prone regions in the world, like Australia—when faced with a threatening sky (although
some swear green means hail). Scientifically speaking, however, little evidence supports either the tornado or hail claims, though there is some
evidence for green thunderstorms.
