Springfield, Illinois – Central Illinois will remain locked in a seasonably cool and damp pattern through Thursday, with highs in the 60s and occasional light rain impacting daily routines and outdoor plans.
According to the National Weather Service in Lincoln, scattered showers are expected to begin after midnight Saturday, with a 20% chance lingering into Sunday morning. Rain chances increase to 30–50% from Monday through Wednesday, especially during afternoon and evening hours. Overnight lows will dip into the mid-40s to low 50s throughout the region.
From Peoria to Champaign, communities should anticipate intermittent drizzle and cloudy skies, which could affect commutes and limit drying time for agriculture. While no flooding is expected, drivers should watch for slick spots early in the day and plan around brief downpours.
Residents are advised to keep umbrellas and light jackets handy. Gardeners should delay fertilizer applications until drier conditions return late week.
The weather pattern may shift toward drier and warmer conditions by Friday, but updates from the National Weather Service will continue as new data arrives.
