Davenport, IA / Moline, IL – The first light of Monday morning reveals a frosty stillness across the Mississippi River Valley — just 4°F under a gray, motionless sky. It’s deceptively calm now, but a midweek pattern change will bring rain, snow, and colder air back to the Quad Cities by Tuesday night.
The National Weather Service in the Quad Cities reports that after a mostly quiet Monday, temperatures rebound slightly into the 30s and 40s on Tuesday. That mild bump will set the stage for a rain-to-snow transition Tuesday night into Wednesday, as a strong cold front sweeps across eastern Iowa and western Illinois.
Meteorologists expect rain to develop Tuesday evening, then change to snow before sunrise Wednesday. While accumulations will likely remain light — less than an inch for most — slick spots may develop on bridges, overpasses, and untreated secondary roads, especially west of the Mississippi. Drivers along I-80 and I-74 should use caution as temperatures dip back near freezing.
By Thursday, highs fall back into the 20s with lows in the single digits. Gusty winds may make it feel closer to zero. The weekend looks cold but dry, with highs struggling to reach 20°F by Friday and Saturday — signaling that December’s true winter pattern has arrived.
5-Day Outlook for Davenport–Moline Area:
- Tuesday: Partly sunny, high 40°F, low 31°F.
