Weather Summary for Iowa
National Weather Service Des Moines IA
1039 AM CDT Sat Oct 20 2018

Strong winds will be the theme of the morning and afternoon as a
potent cold front drops south through the state. Already this morning
several substantial gusts have been observed, including a 59 mile per
hour gust recorded at the Mason City Airport. The strongest wind gusts
of 40 to 50 mph can be expected generally over the eastern half of the
state before winds relax this evening as high pressure moves in. The
light winds and clear skies will allow for temperatures to fall off
into the 20s.  

Dry forecast rolls right into next week with no precipitation expected
through at least Wednesday. Temperatures during that period will be
near to just below normal as a few more fronts cross the region.
Rainfall chances return of the latter half of next week as the weather
pattern begins to shift. Still a lot of uncertainty as to when and who
may see rainfall, but the good news is that the threat for heavy
rainfall will be low which will give local waterways more time to dry
out after a very wet start to the fall.
