Surprised to learn that the clouds are constantly dissipating and have to be fed new vapor from the ground to be sustained; the fact that they go away on the time scale of the eclipse suggests it’a fast process. Then again, when a plane goes by its trail seems to be gone within minutes.

I think there are a few videos on youtube showing clouds just vanishing. I never saw that phenomenon in person but the videos were so unexpected to me that they kept me wondering if they were fake or not. But then again, who would invest so much time and effort in CGI just to show clouds vanishing?

They do this all the time in sub-tropical locations. Cooler moist air from the ocean brings clouds which dissapate over the hot dry land.

Mostly you don’t see it because clouds change at just the right pace for us not to notice them changing.
