It looks like a gust front where cooler air is under cutting and forcing upward warmer and moister air. A bit like a lens cloud on the surface. Would I have let my kids dance around on the pier under that thing? I don’t think so.

It is extremely object-like. "It" seems to move around despite continuously forming and reforming itself at the boarder, while seeming not to "mix" with the "layers" around it. And, of course, the air around it is "pulling" it into place as much as the air in it is "pushing" into new space, so it gets at all of Steve's bidirectional-causality urges. Anyway... if nothing else, it is pretty damned cool to watch: https://youtu.be/InxQlUOYAng?t=58 -. --- - / ...- .- .-.. .. -.. / -- --- .-. ... . / -.-. --- -.. .
