Springfield, Ill. – Drivers south of Interstate 70 may run into a few thunderstorms this evening as a cold front slides slowly across central Illinois, bringing brief rain before drier air takes hold. Temperatures tonight will settle into the upper 60s.
According to the National Weather Service in Lincoln, the boundary will stall south of the region overnight, allowing a more comfortable, seasonable air mass to spread into Illinois. Skies will turn mostly sunny by Wednesday, with highs ranging from 81 to 85 degrees and lower humidity making for a quieter stretch of midweek weather.
Thursday and Friday will continue to deliver comfortable afternoons, with highs in the low to mid-80s and overnight lows dipping into the 50s in some areas. Storm chances remain minimal midweek, with less than a 10% risk of rain.
The next weather shift comes Saturday as another cold front pushes across the state. A slight chance of thunderstorms may return, particularly during the afternoon and evening hours. Outdoor plans should be monitored, and residents are advised to stay alert for updated advisories heading into the weekend.
