Or least it looked like the End of the World when I drove home tonight. Those were the weirdest clouds I have ever seen. Ever. Saint Louisans, back me up.
At about 6:00 I was headed over the river and was a little freaked out by the cloud combinations.
On one hand, there were finely etched detailed Mountainous clouds overhead. Clouds that looked liked they'd been struck from a silver nitrate print, then colorized.
Then there were clouds that looked like some angelic civil servant had seen the pretty clouds, decided they were pornographic graffiti, and painted over them with some cloud whitewash.
It was the most striking as I looked down the river valley. Of course, I was tooling along at 60 mph, and I wasn't going to stop to take photos. I really should have, because the photos I got when I stopped at a light don't give you the whole picture.
Mentally stitch these photos together into a vista of detail clouds with scribble clouds on top:
