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.

Hazardous Weather Outlook For DUBUQUE County,IA

337 PM CST Sun Dec 17 2017


Fog and drizzle will develop tonight over portions of the outlook
area. The potential for dense fog is low, but there is a chance
for some patchy freezing drizzle to occur where the surface 
temperature drops below freezing late this evening into early 
Monday morning. The favored areas are along and east of a line
from DeWitt to Dubuque. If freezing drizzle does occur, it may
linger into the Monday morning commute, especially in far 
northwest Illinois.


Latest indications regarding the Thursday into Friday storm system, 
are that it is shifting the higher potential for accumulating 
snow to the northwest and north of the Outlook Area. It is still 
early for determining the exact track of this system, and those 
with travel plans late in the week should keep up with the latest 
forecasts and updates.


Reports of any slick road conditions late tonight and early Monday
morning would be appreciated.
