Des Moines, Iowa – A surge of arctic air is expected to settle over Iowa late this week, bringing a prolonged stretch of bitter cold and dangerous conditions statewide. Overnight lows are expected to drop to around 4 degrees below zero, while daytime temperatures struggle to climb out of the single digits through early next week.
According to the National Weather Service, the coldest stretch is expected from Saturday through Tuesday as a polar air mass tightens its grip on the Midwest. Northwest winds will frequently add to the severity, driving wind chill values well below zero, particularly overnight and during the early morning hours when frostbite risk increases rapidly.
Northern and central Iowa, including Des Moines, Ames, Mason City, and Fort Dodge, are expected to feel the harshest cold, though southern Iowa will also see prolonged below-normal temperatures. Clear to partly cloudy skies will allow temperatures to drop quickly at night, increasing the risk of frozen pipes and placing added strain on heating systems. While snowfall is not expected to be widespread, isolated flurries could still create slick spots on untreated roads during the coldest periods.
State officials urge residents to limit prolonged outdoor exposure, dress in multiple warm layers, and ensure pets are brought indoors. Homeowners should protect exposed plumbing, and drivers are advised to keep winter emergency kits in vehicles.
The deep freeze is expected to persist through Tuesday, with wind chill advisories or warnings likely as the extreme cold continues.
