...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...
The temperature at Keokuk IA soared to 118 degrees to establish a state
record. (The Weather Channel)

Weather Channel)
...1986...
The temperature at Charleston SC hit 104 degrees for the second day in a
row to tie their all-time record high. (The Weather Channel)
...1987...
Thunderstorms produced severe weather across Minnesota, Wisconsin and
Michigan. Thunderstorms produced wind gusts to 87 mph at Mosinee WI, and
strong thunderstorm winds capsized twenty-six boats on Grand Traverse Bay
drowning two women. Thunderstorms produced nine inches of rain at Shakopee
