I guess I would not call it a "pop" like a light bulb blowing, it just sounded similar to the thump or low frequency I was hearing during the storm.

Sounds like John had a similar issue, I may try powering it off for a bit to see if it gets even better. To be honest, tonight is the first time I've heard this before.

ps: just went out with a spotlight to check for coons on the roof.
