Davenport, Iowa – A prolonged stretch of arctic cold is expected to impact communities along the Iowa–Illinois border late this week, bringing subzero overnight temperatures and dangerous wind chills that could disrupt travel and daily routines. Overnight lows are expected to fall near 2 degrees below zero, with daytime temperatures struggling to recover through early next week.
According to the National Weather Service, a polar air mass will remain locked over the Upper Midwest from Saturday through Tuesday. Even with limited precipitation, persistent northwest winds will drive wind chill values well below zero at times, especially overnight and during the early morning hours when frostbite can occur quickly on exposed skin.
Border cities including Davenport, Bettendorf, Clinton, Rock Island, and Moline are expected to see the coldest conditions. Clear to partly cloudy skies at night will allow temperatures to drop rapidly, increasing the risk of frozen pipes and placing additional strain on heating systems. While widespread snow is not expected, lingering moisture and refreezing could lead to slick patches on Interstate 80, Interstate 74, U.S. 61, and untreated local roads.
Emergency management officials urge residents to limit prolonged time outdoors, dress in multiple warm layers, and ensure pets are brought indoors. Homeowners are advised to protect exposed plumbing, while drivers should carry winter emergency kits in case of breakdowns.
The deep freeze is expected to persist through Tuesday, and wind chill advisories or warnings may be issued as conditions remain dangerously cold.
