Friday night there were some heavy storms across the south central US. I was woken up by “thunder” at about 4:30 in the morning. Here is the weird part. So what I heard several times sounded like a continual rolling thunder clap. Hard to explain in writing, but it was one event that was a continual bah-boom! bah-boom! bah-boom! that was traveling from south to north. It sounded like some super low altitude ship in a sci-fi movie emoting loud speaker noises. Is that a normal weather event? Anyone know what that is? When I think of thunder I think of one clap and it is done until the next clap. And I haven’t heard anything like this that I remember on all my years.
