Dr. Seuss clouds

On our road trip to Ohio to see THE grandbaby we saw these strange clouds shaped like Dr. Seuss illustrations in kentucky. I think they were ahead of the bad storms that dumped all that rain on Missouri and Ohio. The clouds had these pointy shapes and elongated bodies that reminded me of the characters in Dr. Seuss books, like The Cat in the Hat and One Fish, Two Fish and Green Eggs and Ham. I wonder if Dr. Seuss saw such clouds and decided to draw them as his characters, or if it was just a happy coincidence??
