Weather Summary for Iowa
National Weather Service Des Moines IA
441 AM CDT Tue Sep 26 2017

Widespread showers and isolated thunderstorms moved across Iowa during
the overnight hours. Rainfall amounts during the overnight hours were
under a quarter of an inch but many locations last evening over the
western half of the state had rainfall amounts between a half inch to
an inch and a half. Rainfall at the National Weather Service Office in
Johnston recorded 3.64 inches of rainfall from this event. Temperatures
by 4 AM had dipped into the mid 50`s to mid 60`s and were held up in
part due to low cloud cover. A west to northwest wind at less than 10
mph was common across Iowa.

For today the upper level trough of low pressure that has been very
slow to move the last few days will finally swing northeast into
Canada and the Upper Great Lakes while at the surface, a cold front
will move from eastern Iowa into the Great Lakes region. High pressure
will move into the Upper Midwest from the west and usher in much
cooler and drier air than what we have seen the last several days.
Going forward, the high will influence our weather into next weekend.
Look for highs to be in the 60`s and 70`s with lows in the 40`s and
50`s. The next chance for rain won`t come until late in the weekend.
