National Weather Service Des Moines IA
446 AM CST Fri Dec 15 2017

Skies were cloudy across the state throughout the overnight hours. An
area of freezing drizzle moved through portions of central Iowa during
the early morning hours and created a few slick spots on roadways.
This area of precipitation has dissipated. Early morning temperatures
range from the mid 20s in northern Iowa to the lower 30s in far
southwest Iowa. Winds are out of the west to southwest at around 5
to 10 mph. 

Another weak upper level disturbance will move through the region
later today into tonight bringing some chances for light snow or
flurries to far northern and eastern Iowa today into this evening.
Little or no snow accumulation is expected. Warmer air is then on tap
for the Saturday with another slight cool down into Sunday and Monday. 
However temperatures will remain well above average for this time of
year into much of next week. Another weak system could bring some
chances for rain or snow to southern and eastern Iowa Sunday, with dry
conditions returning early next week.
