I don't consider 3 days of heat "longevity." Much of this forum didn't reach 90 on Sunday due to the rain/clouds. It has been a very hot 3 day stretch, no denying that. To me a week of 90+ is longevity. Like this for Philly. If it wasn't for 1 day of 89 degrees, 1995 would have been 25 straight days.
