Weather Summary for Iowa
National Weather Service Des Moines IA
612 PM CDT Thu Jul 19 2018

The western half of the state saw quiet, windy conditions, while the
eastern half saw bouts of rain and a few tornadoes. Areas including
Marshalltown, Bondurant, and Pella saw tornadoes and corresponding
damage. Details coming out of those areas are still coming in, meaning
the best sources of information will be local media, state media, and
subsequent reports coming from the National Weather Service. 

Severe weather and tornadoes aside, temperatures ranged from cool low
70s across the northeast to the upper 80s and low 90s across the
south and southwest. Winds were generally breezy through the day as
well, out of the west behind the front and out of the south ahead of
the front. 

With much of the activity in far eastern Iowa now, the state will see
a period of quiet weather tomorrow, through the weekend, and into next
week. In general, temperatures will be near to below normal with highs
in the upper 70s to mid 80s. The opportunity for showers and storms
will be few and far between, save for an a spotty thunderstorm
opportunity Monday.

...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...
