Most tornadoes occur around sundown hours. Even though water droplets reflect blue light best, when tall storm clouds are present, the water droplets in the clouds are better able to reflect the green light into our eyes than they are able to reflect the warm colors of the sunset — making the sky appear green.
Craig Bohren of Pennsylvania State University explained to AccuWeather that as the sun begins to set, the sky changes from blue to warmer colors like red and orange.
And while green skies are often associated with tornadoes, many believe that their direct association is an overrated myth — green skies are just as likely to occur alongside thunderstorms or other severe weather events. Or you will be told, often with considerable vehemence, that hail causes the greenness. Both explanations are easily refuted by observations. There you have it — while incoming thunderstorms can happen alongside green sky, the two events do not always occur in tandem.
Plus, other weather events are also associated with green skies. So if you suddenly notice a green tint to the sky above you, rough weather might be ahead. But at least the Wicked Witch of the West probably isn't coming for you — nor your little dog. How Do Tornadoes Form? How Are Climate and Weather Different? Green Matters is a registered trademark.

When the light rays come through the clouds, they bounce off of the water molecules.
The distance between the water molecules affects the color of the light we observe when it finally comes through the clouds. That, combined with the colors from an existing sunset for example , is where the green color peaks. And the last, and probably most easily understood theory, is that water is blue and the sky during sunsets is orange.
When they mix, this makes green. The depth in the clouds makes it so that the color is more visible and the light rays mix together, creating a green tint. That being said, it is important to take cover whenever you do come across a green sky tornado, or any other type of major storm event. Here are some things to remember:.
This may be obvious, but it is important to seek shelter during a major storm. You will want to stay away from windows and any other delicate or flimsy foundations. If you live in a tornado-prone area, or have a basement or storm cellar at your disposal, seek shelter immediately. If you are driving and you see a tornado, pull off the road and seek shelter. Do not drive towards it or try to drive past or beside it as they move a lot faster than they appear to.
Tornadoes can also switch their direction very suddenly. If you are in an emergency situation where the tornado is too close to you, get as low as you can by laying flat in a ditch. Most tornado-prone areas already have designated basements and storm cellars in case of these situations. However, tornadoes are very unpredictable and can sometimes even form within urban areas.
