Weather Summary for Iowa
National Weather Service Des Moines IA
620 PM CDT Tue Oct 23 2018

Another day of quiet fall weather across the region as an area of high
pressure supplied clear and calm conditions. Highs were a little
cooler than yesterday, generally in the 50s across much of the state.
The tranquil conditions will continue into tonight as lows bottom out
in the upper 20s to mid 30s. 

Pattern begins to shift by late Wednesday as an area of low pressure
approaches from the west. This will spur chances for rainfall
Wednesday night into Thursday, mainly over the western half of the
state. Cloud cover will hold in place over much of the area through
the end of the week, with additional rainfall chances Thursday night
into Friday. Highs look to hold in the upper 40s to mid 50s, which is
just below normal for late October. A few frontal passages over the
weekend will bring additional chances for light rainfall. Conditions
on Sunday may become quiet blustery. The weather front quiets down
again early next week, but another system entering the Plains may
bring rainfall chances for Halloween.
