We've only lived here in eastern New Mexico, right on the western edge of Tornado Alley, for a couple of years. When we get scary skies, I start to feel anxious and start scanning for the greenish tints that mean watch out! Take shelter!
Was the sky really this green on the stormy day when I took this shot? No, but this is just exactly how it felt to me.
Take a look at other skies, both stormy and peaceful, all around the world on Skywatch Friday.
