I agree. "Stormy weather" means windy and wet in the minds of
the public, and in mine too. If the sky looks thundery people call it
thundery, not stormy.

I think it must vary from person to person - when I hear someone saying
"It's going to be stormy tonight", I would assume that thunderstorms
are expected overnight.

The forecast said "Storm Warning" that I'd not seen before. I suppose
it's down to public perception; maybe it was thought that something
different from "Severe Weather Warning" would make people take note.

I personally prefer the word "Windstorm", which is used in my job (in
the insurance industry).
