For those who may be wondering, the storm last night was exactly what I was describing in "A History of Lightning." As it approached, the lightning was coming so fast that I could walk through my house at midnight without having to turn on a light or use a flashlight. The only thing that broke the constant roll of thunder was the louder reports of strikes that were ground-to-cloud and right near us. I know some people have never experienced such a storm and thought that what I was describing was part of the "fantastical" nature of the story. Except for the thunderhead at the front of the storm with the front wall of a skull (or with the internal lighting our main character thinks it looks like a skull), everything else in there (related to the storm, not so much what the characters do in the storm) I've seen before.
And yes, I watched it closely to make sure I could describe it better later.
Mother nature can be awesome, she just has to remind us sometimes.
