It's not something you see every day: a horizontal cloud, vibrant orange and rotating, that's taken over the sky.



But that's just what people got to see online this week after a couple in Timbercreek Canyon, Texas, spotted a "weird-looking cloud" and posted a video of it.

Now questions abound: What is it exactly? And what are the chances you'll get to see one in person?

It's called a "roll cloud," which is a type of arcus cloud—low, horizontal formations typically associated with thunderstorms. Depending on the conditions, a roll cloud "can last for several hours and extend for several hundred miles," said Stephen Corfidi, a meteorologist at the National Oceanic and Atmospheric Administration (NOAA).

2. I have seen it one time

Chicago on or near May 1980. Scared the piss out of me because it looks like something wicked coming. It was very surreal, it came in a straight line with sunny nice blue skies on one side and this thing rolling in.

4. I think I saw one in Wyoming,

a few miles out of Cheyenne several years ago. Part of it had drooped down and was lying across the highway like an enormous slug. I would guess it was about 10-15 ft. in diameter. It was the weirdest thing I had ever seen. It wasn't orange. It was greyish white.
