Weather Summary for Iowa
National Weather Service Des Moines IA
505 AM CDT Wed Sep 20 2017

A cool front continues to move across Iowa early this morning. A
diminishing line of showers will weaken as it heads into the eastern
counties prior to sunrise. Clouds and south winds of 10 to 15 mph remain
ahead of the front with temperatures in the lower to mid 70s while 
behind the boundary readings have cooled to the lower 60s in northwest
Iowa with light northwest winds. 

The front moving through the state today will slow over eastern Iowa
this afternoon and then become stationary just south of the state
tonight. This will result in chances for showers and thunderstorms
over the east and southeast this afternoon. Tonight with return flow
over the front showers and thunderstorms will increase in coverage
across southern Iowa. Both late this afternoon and tonight a storm or
two may be strong enough to produce strong winds or large hail. By
Thursday through Saturday the front will lift north of the state with
warm and breezy conditions. Unseasonably warm air will move across the
region with highs in the upper 80s to lower 90s from Iowa northeast
into Minnesota and Wisconsin. Highs through the period will 10 to 15
degrees above normal. Sunday will be a few degrees cooler with afternoon
highs in the 80s as more clouds move back into the region by that time.
Our best chances for thunderstorms will arrive by late Sunday and into
the beginning of next week as a large storm system over the western
United States finally slides east.
