Weather Summary for Iowa
National Weather Service Des Moines IA
500 PM CDT Mon Oct 22 2018

A spectacular fall afternoon is coming to a close as the sun starts to
set over Iowa. Highs today were comfortably in the 60s, and even a few
readings in the 70s in the southwest corner of the state. Abundant
sunshine will continue into tomorrow, but temperatures will take a
step back as cooler air filters into the region. Highs Tuesday should
range from the upper 40s across the north to mid 50s in the south with
northerly winds at 5 to 10 miles per hour. 

The dry pattern across much of the region looks set to come to an end
over the second half of the week as a few low pressure systems cross
the Plains. The best chances for light rain look to be late Wednesday
into Thursday, then again late Friday into Saturday. Highs through the
end of the week will generally hover in the upper 40s to mid 50s,
which is 5 to 10 degrees below normal for late October.
