Weather Summary for Iowa
National Weather Service Des Moines IA
1014 AM CDT Tue Sep 19 2017

Areas of dense fog continue to dissipate over central Iowa this
morning, while the eastern third of the state remains under a
relatively thick layer. Visibilities here have improved slightly, but
remain around a quarter mile or less. Temperatures are in the low to
mid 60s statewide and winds are mostly out of the east southeast
around 5 mph or less.

Fog remains across much of the Midwest as well, stretching northwest
from central Illinois across much of Iowa, Minnesota, and the Dakotas
behind a weak warm/stationary front. This front will begin to lift to
the northeast through the day, and daytime heating will gradually
break apart the fog by afternoon. More sunshine will return by late
afternoon and allow temperatures to warm into the low to mid 80s
across much of Iowa, especially in the southwest, where skies will
clear faster through the day. Wind speeds will increase by afternoon,
eventually reaching 15-20 mph out of the southeast.

An area of low pressure currently over western North Dakota will move
eastward today, dragging along a cold front across the Northern
Plains. Showers and even potential severe storms will be possible as
this front approaches eastern parts of the Dakotas and western
Minnesota. Rain chances over Iowa will be limited to the northern
parts of the state overnight as the front moves through.

On Wednesday the front continue through the region, dropping high
temperatures in northwestern Iowa down into the 70s. Ahead of the
front, eastern and southeastern Iowa will again reach the mid 80s for
high temperatures. Rain chances will be limited to the southeastern
part of the state late Wednesday and overnight into Thursday morning.
Clear skies and even warmer weather return on Friday, when high
temperatures will reach 90 degrees across much of the region. Saturday
will be slightly cooler, but still sunny. Rain chances return later on
Sunday into Monday.
