Nano, was that your view of the Derecho as it swept by to the South of you?
No, the derecho was 3 or 4 days earlier; this was a different system. As thunderstorms go this one would have been thought pretty standard, but its lightshow was remarkable enough that everyone talked about it. Even took the meteorologists by surprise, although they had an explanation: a higher than usual concentration of ice crystals in the cloud formations, I think it was.
Found an actual shot of the electrical storm, seen here at a George Floyd memorial:

Still not really raining yet. Now imagine such discharges carpeting the sky for as far as the eye could see, eerily silent, not high and far away but uncomfortably close overhead, often writhing, new ones every half second and overlapping, with the whole show going full-bore for a few hours straight, and you've got the idea. There was very little wind - just that crazy, living sky. Made me think of Chinese dragons coming out to play.
I didn't want to go out, but I had to before the rains started; so, since the horizontal nature of the lightning hadn't been converting to ground strikes at all for some reason, I took that bet and had a drive under the fireworks. Wherever you were you couldn't help but look up at the arresting spectacle, so I had to be extra-attentive behind the wheel. They could've made a movie scene out of that. The rains didn't come until an hour after I'd made it back home, and they were heavy, but otherwise comparatively normal if you factored out the spellbinding visuals.
