The huge derecho that ripped through South Dakota, Minnesota, and Iowa on Tuesday, July 5 was the second one to hit the area this summer. It was more of the same; hurricane-force straight-line winds, large hail, dangerous thunderstorms, and even a couple of tornadoes.

While a green sky during a thunderstorm isn't exactly rare, I would say the magnitude of this one was different. I certainly hadn't seen a green sky quite like that in the 25 years I've been in the upper Midwest.

Now there is a new video of the green skies that was posted showing how dramatic the color really was. Check out the video below.
