Where were you in mid-July 1995? Also, is past 16 years chosen to
exclude 1991, which had some nasty heat?
If you want past midwest heat, look at early July 1936, which was a high
point of the "dust bowl" heatwaves. I think about 20 US states, mostly
Plains-Midwest but also Pennsylvania have statewide alltime record highs
from that single heatwave.
And farming techniques were since changed over hundreds of thousands of
square miles of USA farmland to stop and reverse what appears to me
desertifying of much of the Plains and Midwest due to the farming
techniques of the 1930's and earlier. Some of the improvement took time -
Illinois has its statewide alltime record high temperature in the late
1950's IIRC, at East St. Louis.
Meanwhile, yearround temperatures in the Plains/Midwest have shown a
trend of getting warmer in the past decade or two, despite summer peaks
not breaking the more spectacular dustbowl records.
Now, for Philadelphia: January 1932 was freakishly warm, possibly
unbeatable even for the next 100 years. The alltime high for Philadelphia
was from an early August day at a time back when the official thermometer
was downtown - it's now close to a half-mile-wide river. Since the mid
1980's there has been a trend of things getting warmer, despite lack of
alltime July record high since 1964 or alltime August high since much
farther back.
