Remember that summer very well. I was working near Cincinnati and remember the rule of thumb was if it hit 94 by noon it was going to be a 100+ day. It happened a lot that summer. Also the first time I recall people losing their entire lawns, (not dormant but actually killed off). Many people had to have them re-seeded, sodded.
On separate note, that was also the first time I felt an earthquake....it was later during that same summer.
