Have you ever seen these clouds before?

Beautiful setting or backdrop!!!

I actually saw these clouds on a day it was set to rain but definitely unexpectedly as the sun was setting. I started to wonder if something was on fire miles away or if I had actually stumbled upon something that would blow the mind if many cloud enthusiasts. So I figured why not post it here for my Seemit family to see and grab some feedback because it looks nothing like something I ever studied in school.

What do you guys think?
