Davenport, Iowa – Drivers across eastern Iowa and northwestern Illinois are urged to use caution this evening as light snow and freezing drizzle create slick travel conditions along major corridors including Interstate 80, Interstate 74, and Interstate 280.
According to the National Weather Service Quad Cities office, light snow accumulations under one inch are expected through the evening hours. In addition, a transition to freezing drizzle is occurring in parts of the region as ice crystals aloft diminish, allowing supercooled liquid droplets to reach the surface.
Forecasters report that freezing drizzle has already been observed in portions of southeast Minnesota and is expanding into northeast Iowa and northwest Illinois. While snowfall amounts will remain light, the freezing drizzle may deposit a thin glaze of ice, particularly on bridges, overpasses, sidewalks, and untreated secondary roads.
The advisory remains valid through 8 p.m., with the highest risk focused near the Quad Cities metro area, Cedar Rapids, Iowa City, Dubuque, Moline, Rock Island, and surrounding communities. Roads that appear merely wet may become slick with little warning, especially as temperatures hover near or below freezing.
Transportation officials remind drivers that bridges and overpasses freeze first, increasing the likelihood of sudden loss of traction. Slower speeds, increased following distance, and gentle braking are recommended during evening travel.
The National Weather Service advises motorists to check local road conditions before heading out. In Iowa, travelers can visit 511ia.org, while Illinois drivers are encouraged to use gettingaroundillinois.com for real-time updates.
While no significant snow accumulation is expected, forecasters emphasize that freezing drizzle can be more hazardous than heavier snowfall due to its ability to create invisible ice. Conditions should gradually improve later tonight as precipitation tapers off.
Residents are encouraged to remain weather-aware and avoid unnecessary travel during the advisory window if possible, especially on untreated roads and elevated surfaces.
