Hubby and I were watching the storm out the window, keeping and eye on some major trees nearby, when the whole sky to the west lit up from the ground up.
It was this bright, intense green blue, and it was acompanied by a very audible FFZZZZZZZZTTTTTT! and you could feel the electrical surge. Power went off, and came back on sometime early morning.
I haven't been able to find what happened, possibly a lightning or tree strike on a power station. Was scary though.
