Iowa and Illinois are starting the day wrapped in thick fog as headlights glow along the Mississippi River bridges. In the Quad Cities, temperatures hover near 31 degrees, and visibility drops sharply in spots along and north of Interstate 80.
A Dense Fog Advisory remains in effect until 10 a.m. for parts of northwest Illinois and east central to northeast Iowa. Visibility may fall to one-quarter mile or less. Slick patches are possible near the Highway 20 corridor where moisture lingers on cold pavement.
Conditions gradually improve late this morning. Skies stay mostly cloudy, with highs near 49 degrees in Davenport and Moline. Rain chances increase tonight, especially after midnight, with patchy fog redeveloping and lows around 42.
Thursday brings scattered showers, mainly before noon, with highs near 56 degrees. Storm chances ramp up again Thursday night into early Friday. The Storm Prediction Center places the region in a Level 2 of 5 risk for severe weather Friday and Friday night.
Friday turns warmer and more unsettled. Highs climb to 72 degrees with rain and thunderstorms likely. Large hail could be the primary threat late Thursday night, while damaging winds become the main concern Friday evening into the night.
Friday night cools quickly, with lows around 42. If temperatures fall faster than expected after rain, isolated slick spots could develop in low-lying areas.
Saturday dries out with sunshine and highs near 55. Sunday rebounds into the low 60s under mostly sunny skies. Early next week trends even warmer, with highs reaching the 70s by Monday. The 6–10 day outlook favors above-normal temperatures across eastern Iowa and western Illinois.
