Davenport, Iowa – Roads across eastern Iowa and northwest Illinois could turn dangerous late Sunday night as falling temperatures push surfaces below freezing after 10 p.m., setting the stage for slick travel from the Quad Cities to Dubuque and Burlington.
According to the National Weather Service Quad Cities office, wintry conditions were spreading southeast Sunday evening from western and northern Iowa, with rain changing to snow as colder air moved in. Air temperatures were expected to drop below freezing first, then pavement temperatures would follow a couple of hours later, increasing the risk for icy roads, bridges and overpasses overnight. The agency said northerly wind gusts would climb above 45 mph between 6 and 8 p.m., while temperatures fall into the 20s area-wide by 10 p.m.
The shift will affect travel across a broad stretch of Iowa and Illinois, including the Quad Cities, Cedar Rapids, Dubuque and Burlington. Snow was already developing farther west by late afternoon, with heavier bands pushing east. Conditions may worsen quickly once snow begins to stick and untreated roads cool.
Drivers are urged to delay non-essential travel as conditions deteriorate. Anyone who must head out should slow down, leave extra stopping distance and check Iowa 511 and GettingAroundIllinois for live road conditions. Charge phones before travel and keep a winter kit in the vehicle in case roads become impassable.
The threat will continue through the night, and additional alerts or travel advisories may follow as the colder air deepens across the region.
