It just came out of nowhere. An enormous blast that went on for seconds. It was thunder but it felt like a bomb! The windows shook and car alarms were going off all around the neighborhood. I lived here my whole life and never heard anything like this before. Five minutes later it happened again but from the opposite side of my house. Same thing. A little rumble then a massive BOOM!!! then the shockwave! I hope it goes on all night! This is a once in a lifetime experience.
