Springfield, Illinois – Central Illinois residents are set for another stretch of mild summer weather through Monday morning, but heat and humidity will make a noticeable return as the new week unfolds. According to the National Weather Service in Lincoln, dry skies will dominate through Sunday, with temperatures climbing from the upper 70s to mid-80s by Tuesday.
Scattered thunderstorms could pop up in southeast Illinois Monday afternoon and again Wednesday, while central Illinois, including cities like Decatur and Bloomington, faces a chance for isolated storms by Tuesday afternoon. The risk is low—just 15% each day—but any downpours could bring brief gusty winds and lightning, especially in open areas and along major routes like I-55 and I-72.
Drivers and outdoor workers should keep an eye on rapidly changing skies, especially early and late afternoons. With humidity climbing, residents are advised to stay hydrated, limit strenuous outdoor activity during peak heat, and review storm safety plans. Air conditioners may get their first real workout since July, and local officials remind everyone to check on vulnerable neighbors as temperatures rise.
This pattern of warm, sticky days with occasional pop-up storms will continue through Wednesday, with more updates expected if watches or warnings are issued.
