From Wxrisk.com — ACTUAL CLOUDS not photoshopped-- from GORHAM MAINE ... FROM wmur TV in NH

Even when the sky is clear the atmosphere is still moving like this.

This is one of the reasons why getting an extended forecast down to an exact science is very very difficult and probably why artificial intelligence is not going to solve the weather problem once you go past 7 or 10 days
