Why The Sky Turns That Eerie Green Right Before The Worst Storms, Explained

That sickly green glow isn't your imagination, and it's telling you something.

You've seen it, that moment the whole sky goes a weird bruised green before a big storm rolls in. It looks like something out of a movie, and it always makes people stop and stare.

The color comes from the way late-day sunlight scrolls through the deep water content of a towering storm cloud. Red light gets scattered out while blue-green light bounces back down to your eyeballs.

It doesn't guarantee a tornado, but it does mean you're looking at an unusually tall, water-loaded thunderhead, which is exactly the kind that produces hail and violent winds.

So the next time the sky turns that unsettling shade, treat it as a free warning. Your ancestors read the same signal, they just didn't have a phone to film it.
