Weather Summary for Iowa
National Weather Service Des Moines IA
518 PM CDT Fri Jul 20 2018

After an eventful day with a few destructive tornadoes yesterday, the
area was greeted with a much needed quiet day weather wise. Scattered
clouds were seen as the big upper level low pressure system moved to
the east, also providing some breezy northwest winds around 15 to 20
mph and gusts to 25 plus mph at times. Highs were very comfortable,
generally a few degrees below normal, in the mid 70s to low 80s in
most locations. 

The story going forward will be for overall quiet and comfortable
weather for mid to late July. The weather will predominantly be quiet
with only a couple scattered opportunities for showers or storms next 
week, and temperatures in the upper 70s to mid 80s for highs.

conditions developed. Toward the end of the month state records were set
for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David
Ludlum)
