1999 would be amazing if the analog rolled forward to July....1994 not so much. Wasn't 1994 the year where we had an early summer but the heat peaked early and we cooled down for July? But there was a vast difference between NYC and Philly, and Philly was almost as hot as they were in 1993? I'm curious, why can't we use 1991 and/or 1993 as analogs, those were two of my favorite summers. 1991 and 1993 were both two of our hottest.
Also what about 2011? I see that in the list too. I only remember the amazing heat in late July, but it looks like June was extremely hot too. August was extremely rainy though so not the ideal summer.
