Weather Summary for Iowa
National Weather Service Des Moines IA
520 PM CST Sun Dec 17 2017

Today was rather interesting across Iowa. Most of the state has seen
wide spread stratus cloud cover since the morning hours. Throughout
the afternoon, central Iowa did have some substantial breaks in cloud
cover. There have been reports of light rain showers throughout the
state, with traces of snow sprinkled in. Temperatures this afternoon
hit the mid to upper 30s. Winds have not been strong, coming from the
northwest at less than 5 miles per hour. 

The rest of the Midwest has experienced similar conditions in terms of
cloud cover and isolated rain showers. Temperatures in Missouri and
Kansas were a little warmer, with high temperatures in the mid 40s. 

For this evening, some portions of Iowa will see cloud cover
dissipate, others will see the cloud cover linger. No substantial
precipitation if any is expected this evening. Temperatures will drop
into the mid 20s, and perhaps a few degrees cooler in areas where the
cloud cover dissipates. For heading into the start of the work week, 
temperatures will rebound back into the mid 40s.

snow to the northwest and north of the Outlook Area. It is still 
early for determining the exact track of this system, and those
