So anyone else here seen “The Mist”?  All I could think of when I saw this…

This is so cool can someone explain the scientific phenomena behind this?

Just checked, this is a shelf cloud, a type of arcus cloud that usually signals the coming of severe weather. This is actually fairly normal behavior for shelf clouds, I think it’s just that the video is really close to the squall so it looks extremely ominous.

Here are a few more examples of shelf clouds.
