I've never seen a case of precitation static occuring that way.

I experienced that kind of static in Arizona with wind, extremely
low humidity, and bare wire. I've never experienced it in East
Texas.

Isn't this the triboelectric effect? I read this was a big problem for
certain newer wireless applications.

Energized TV antennas always feel 'gritty' when I brush my fingers
lightly across them. Why is that? I also get a very mild shock
sometimes, but that gritty electric sandpaper friction is very strange.

Also the indoor TV antenna collects dust and vaporized
cooking oil like there's no tomorrow. Is this like a Tesla coil?
