The heavens are colored by the powerade. The sky in Sioux Falls, South Dakota turned a shade of green before a storm hit yesterday.

The ominous occurrence took place as a massive thunderstorm system called a derecho swept through the region, wreaking havoc on the property and power supplies of thousands of others.

The power and destructiveness of the Derechos are known for their ability to travel hundreds of miles. The Washington Post reports that the neon hue seen yesterday is very rare.

There are a number of theories as to why the green skies occur, with the main one being that heavy rain and hail scatter and reflect light.

In the late afternoon and evening, when the sun is setting, there is a chance of storms. It's thought that water is good at holding the blue color and that it's also good at scattering light. If a storm has enough liquid power behind it and hits at the right time of day, yellow and blue light will combine into green.

The storm pushed this question to the edge.

The colors exhibited by storms over the James River Valley and northwest Iowa were unlike any in recent meteorological memory.

The Derecho sweeps through five states with 90 mph winds.
