Davenport, Iowa – Snow is expected to develop Sunday afternoon, with up to 3 inches possible in parts of eastern Iowa and western Illinois, potentially impacting travel along I-80 and I-74 after 2 p.m.
Forecasters indicate accumulating snow will be possible Sunday afternoon through Sunday night, especially in areas south of I-80. Cities including Davenport, Burlington, Muscatine and Galesburg could see plowable snowfall if the storm track aligns favorably. Current projections suggest minor to locally moderate travel impacts, but exact totals and placement remain uncertain.
Motorists traveling along I-280 and US-61 should prepare for changing road conditions late Sunday. Snow may begin as early as mid-afternoon, becoming steadier into the evening hours. Bridges and overpasses are likely to become slick first as temperatures fall.
The highest probability for several inches of accumulation currently appears south of the Quad Cities metro, though even a slight shift in the storm track could move heavier snow bands north or south. Areas near Burlington have roughly a 30 to 40 percent chance of experiencing at least minor travel disruptions.
Road crews will monitor pavement temperatures and pretreat highways as needed. Drivers are encouraged to check updated forecasts before traveling Sunday evening and allow extra time to reach their destinations.
Conditions should gradually improve early Monday as the system exits the region. However, lingering slick spots may persist for the Monday morning commute if snowfall amounts trend higher.
Residents are urged to stay tuned for forecast updates as confidence in snow totals and impact zones increases over the weekend.
