Get ready for a cool change, Central Illinois. A strong cold front is moving in this week, bringing rain showers and some of the chilliest daytime highs seen so far this season. After weeks of warm weather, residents should prepare for upper 60s temperatures, wet conditions, and crisp mornings.
Cooler Temperatures Take Over the Region
According to the National Weather Service in Lincoln, much of Central Illinois will feel noticeably cooler from Wednesday through the weekend. Highs on Thursday may barely reach the upper 60s — a rare dip for early September, and possibly near record-breaking for this time of year.
There’s a 70% to 80% chance that below-normal temperatures will stick around through at least Saturday. The cool front will also make mornings feel chilly, especially in rural areas where temperatures could dip into the upper 40s.
Midweek Rain Showers Likely
Along with the cooler air, scattered rain showers are expected to move in on Wednesday and continue into Wednesday night. The chance of rain is around 30% to 40%, with light showers most likely along the I-72 and I-55 corridors.
Commuters in cities like:
Bloomington
Peoria
Decatur
should be prepared for wet roads and possible delays. Outdoor events in areas like Champaign and Springfield could face schedule changes or cancellations due to the incoming rain.
Plan Ahead for Chilly Mornings and Outdoor Conditions
Residents are encouraged to plan for the drop in temperatures and the possibility of rain. Here are some useful tips:
Keep a jacket or umbrella with you
Postpone outdoor work during wet periods
Dress in layers, especially for early morning errands or school runs
Watch for updates if conditions change or rain chances increase
Highs are expected to remain in the upper 60s to near 70 degrees through Friday, giving the area a true early fall feel — even if it’s still technically summer.
Cooler Pattern Likely to Linger Through the Weekend
This stretch of cooler, rainy weather isn’t going away quickly. Forecasters say the pattern could continue into the weekend, with additional advisories likely if rain chances increase or wind picks up.
For now, this midweek front will bring a noticeable break from the summer warmth. It’s a good time to check your closet for autumn layers and plan your week with the weather in mind.
