I vaguely remember as well. We had a chance for severe storms here that day, but everything stayed well northeast as we were very hot and capped. Do remember seeing the anvil in the eastern sky while we baked.
I remember '88 well, it was the hottest summer by far that I've experienced. '12 gave it a good run. Guess I don't sense the mean very well, as it doesn't seem like it's gotten any warmer at all since I was a youngin'.
