Des Moines, Iowa – A mid-January warm-up could bring periods of rain to parts of Iowa while increasing the risk of freezing rain and slick travel conditions in colder northern areas as temperatures fluctuate near freezing.
According to the National Weather Service Climate Prediction Center, Iowa is favored to see above-normal temperatures during the January 9–13 period, with precipitation trending near normal. This pattern supports rain across southern and central Iowa while allowing mixed precipitation to develop farther north where colder air lingers near the surface.
Northern Iowa, including Mason City, Decorah, and areas near the Minnesota border, faces the highest risk for freezing rain, particularly during overnight and early morning hours. Even light ice accumulation could create hazardous travel on I-35, U.S. 18, and untreated secondary roads.
Across central and southern Iowa, including Des Moines, Ames, Ottumwa, and Council Bluffs, precipitation is more likely to fall as rain, limiting snow chances but leading to wet roadways and reduced visibility during heavier showers. Brief nighttime cooling could still allow isolated slick spots to form on bridges and overpasses.
Drivers are encouraged to monitor changing conditions closely and allow extra travel time as temperatures fluctuate. Additional advisories may be issued as confidence increases closer to mid-January, especially if colder air lingers longer than expected across northern Iowa.
