...1930...
The temperature at Washington D.C. soared to an all-time record of 106
degrees. The next day Millsboro reached 110 degrees to set a record for the
state of Delaware. July 1930 was one of the hottest and driest summers in
the U.S., particularly in the Missouri Valley where severe drought
conditions developed. Toward the end of the month state records were set
for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David
Ludlum)
...1934...
