Weather Summary for Iowa
National Weather Service Des Moines IA
1059 AM CST Mon Dec 18 2017

Areas of dense developed once again overnight, this time over portions
of central and southern Iowa including the Des Moines metro. The fog
reduced visibility down to a quarter mile or less at times and created
a few slick spots on roads as temperatures were near or below
freezing. The fog has mostly dissipated as of late morning, giving way
to mostly sunny skies across the state of Iowa. Temperatures through
the next 3 days will be quite mild for mid December with afternoon
highs in the 40s and 50s. 

Significant changes are on the way for the end of the week as colder
air plunges south into the region. Chances for rain or snow arrive on
Thursday and continue into Thursday night and Friday. Some parts of
Iowa may see their first accumulating snowfall of the season. The best
chance for accumulating snowfall looks to be across northern Iowa, but
cannot be ruled out for locations further south at this time. A
significant drop in temperatures is expected as the system departs 
the area, which will likely keep temperatures below normal through the
weekend and the Christmas holiday. Additional chances for light snow 
are possible through the weekend. Those with holiday travel plans 
should monitor the forecast through the week for winter weather 
updates.
