Springfield, Illinois – Scattered thunderstorms and steady showers will linger across Central Illinois through Monday evening, with cities from Springfield to Effingham likely to see the heaviest rain and minor flooding on local roads.
According to the National Weather Service in Lincoln, a slow-moving upper-level low is pushing bands of precipitation across the region, with peak rainfall expected Sunday afternoon and early evening. Rain totals could range from 0.5 to 1.5 inches in southeastern counties, especially near Effingham and Mattoon.
In Springfield, rain chances rise above 60% by midday Sunday, with temperatures staying in the low 50s to mid-60s through Monday. Danville, Decatur, and Champaign could see repeated downpours during commute hours. Temperatures will also remain below seasonal norms, with lows dipping into the 40s Sunday and Monday nights.
Drivers should watch for ponding on rural roads and low-lying intersections, particularly in southeastern Illinois. Residents are urged to avoid driving through standing water and check gutters and drains to prevent minor flooding. With ground saturation increasing, isolated power outages are possible if storms bring gusty winds.
Rain chances taper off Tuesday, but lingering showers could return midweek. More updates are expected if rainfall totals rise or additional advisories are issued.
