Quad Cities, IA/IL – A stretch of milder weather across eastern Iowa and northwest Illinois will give way to rain, strong winds, and a brief blast of colder air later this week, creating rapidly changing conditions.
According to the National Weather Service office in the Quad Cities, warmer temperatures through midweek will lead to snowmelt and patchy fog, especially during overnight and early morning hours. Daytime highs are expected to range from the mid-30s to mid-40s through Wednesday.
Rain is likely late Wednesday night into Thursday morning, with temperatures continuing to rise overnight. Forecasters say rainfall amounts should remain light, though wet roads could impact the Thursday morning commute.
Conditions will change quickly Thursday afternoon, as a strong cold front moves through the region. Behind the front, northwest winds are expected to strengthen significantly, with gusts likely exceeding 40 miles per hour. The strongest winds are forecast during the Thursday afternoon and evening hours.
As colder air pours in, temperatures will fall sharply Thursday evening into Friday morning. The combination of falling temperatures and strong winds is expected to produce wind chills in the single digits above and below zero, creating bitter conditions late Thursday night.
There is a low chance, around 20 percent, that rain could briefly mix with or change to snow Thursday afternoon or evening, though any accumulation is expected to be minimal. Visibility could be briefly reduced in heavier bursts.
By Friday, highs are forecast to range from the upper 20s to mid-30s, with winds gradually easing. Temperatures are expected to moderate again heading into the weekend.
The National Weather Service advises residents to secure loose outdoor items, use caution when driving high-profile vehicles, and stay updated as conditions evolve.
