Breaking up much, much earlier than Dallas?

Possibility.

Look at the radar loop and you'll see red blips (not clouds or atmospheric reflections) between New mexico, Amarillo, Lubbock, and Dallas ... Several hundred miles before the main plume begins.

CNN, as usual, has nothing but the same endless loop of the one TV shot.

I heard a report that said that telescopse in California could see pieces beginning to come off when it passed over them.

I saved it as a series of screen caps. I don't know how to set it up as a rotating loop, though.

Do you have a link to that radar?
