Springfield, Ill. – Central and Southeast Illinois will experience summer-like warmth through the middle of the week, but residents should be prepared for a higher chance of thunderstorms, particularly on Wednesday afternoon, with severe weather still a possibility.
Warm Weather Through Midweek
According to the National Weather Service in Lincoln, temperatures will climb into the mid to upper 80s through Thursday, with Tuesday expected to reach near 90°F in some areas. While Monday and Thursday will have minimal rain chances (around 20%), drivers should be aware that pop-up showers are still possible during peak heating hours.
Thunderstorm Risk on Wednesday
The weather will take a more unsettled turn by Wednesday, when a 70% chance of thunderstorms will develop, bringing the highest risk for lightning, heavy rain, and possible wind gusts. Areas like Peoria, Decatur, and Champaign are expected to see the greatest impact. Localized downpours could affect afternoon and evening commutes, especially on I-55 and I-72, so it’s important to stay cautious while traveling.
