Des Moines, Iowa – Bitter cold conditions are expected to return to Iowa at the end of the week, bringing dangerous wind chills to much of the state and increasing health and travel risks, especially during early morning hours.
According to the National Weather Service in Des Moines, another surge of Arctic air will arrive Friday morning, with wind chill values dropping into the -10s across central and northern Iowa. Some areas could briefly experience even colder readings, particularly during the pre-dawn hours Friday and again early Saturday.
Cities including Des Moines, Ames, Fort Dodge, Marshalltown, Waterloo, and Mason City are expected to see the coldest conditions. Wind chills near Interstate 80, U.S. Highway 20, U.S. Highway 30, and Highway 14 may make outdoor travel and commuting hazardous, even where roads remain dry.
Forecasters warn that exposed skin can develop frostbite in as little as 30 minutes under these conditions. Residents are encouraged to cover exposed skin, limit time outdoors, and ensure pets are brought inside. The National Weather Service also recommends checking on vulnerable individuals and ensuring home heating systems are functioning properly.
The cold air follows a brief period of more moderate temperatures but will reinforce winter conditions heading into the weekend. While widespread snowfall is not the primary concern with this system, the combination of cold temperatures and wind may exacerbate existing icy patches on untreated roads, bridges, and overpasses.
Temperatures are expected to slowly moderate later in the weekend, though overnight wind chills may remain below zero in some locations.
Early-morning commuters, students waiting for buses, and outdoor workers should take extra precautions Friday morning, particularly along major roadways where exposure times may be longer.
