This morning...the loudest ever thunder clap I have ever heard or experienced... nearly blew out my ear drums and the house has never shook and vibrated this much ever before. The term thunderstorm, it literally was just thunder. Since I was asleep at the moment, I didn't see the flash, but I did see it, while my eyes were closed. I felt like it was just a few feet above overhead. Because it was so close, both the flash and clapped were synchronized. I have never ever heard a secondary reverberation of the original clap and this one time I did and it was echoing it's way away.
Fortunately it was an arc of plasma that only came close to ground and did not make landfall. I had my fan blowing on me while I was asleep so I could not tell how the ionization in the air was. I was too physically tired, so I didn't wake up to to wander around at that moment. Now that I'm up, it's sunny outside and only a hint of some moisture. Nothing around outside shows any indication of a storm front. Radar map online shows thunderstorm around outside my area and I seem to be in an eye of calmness. It sunny and clear outside at the moment. Daily weather prediction is scattered thunderstorms. Current time is about 11am...that thunderclap was about 8:30 am.
