This is the second seriously close call we've had. The first was a few years ago when we were living in Hampton & a tornado tore through the Atlanta Motor Speedway.
Anyway, what I've learned is that when there's constant lightning going HORIZONTALLY through the sky, you get a tornado. I've seen it twice in my life, & both times, there's been a wretched tornado.
My mom taught me when I was little that if the sky turned green, there would be a tornado, and I think that's true in the Midwest, but not so true down here. Of course, it's also not helpful when they come at night.
Public Service Announcement is now over. Thank you for your attention. ;)
