Wow this is interesting- Allentown has been averaging more 90 degree days than NYC/ Don both of those summers you mentioned were hot but not extreme, I don't believe either had any 100 degree days here and neither was among the top for number of 90 degree days? They were just consistently very warm to hot without being extreme. 1988 could have been but the extreme heat was to our west, and Long Island and the city didn't reach 100 like they did in years like 1977, 1980, 1983, 1991, 1993, 1995, 1999, 2010, 2011, for example.
