CHAMPAIGN, Ill. – Central Illinois heads into a stretch of late-summer heat with Friday shaping up as a sunny but hot day. Drivers along I-72 and local roadways should prepare for heat and sun glare as highs push near 91°F. Staying hydrated and limiting extended outdoor activity remain critical through the weekend.
According to the National Weather Service in Lincoln, Friday will stay mostly clear with light winds shifting southeast around 6 mph. By Saturday, highs rise into the mid-90s, and Sunday could top out near 96°F, marking one of the hottest September days so far. Lows overnight will offer little relief, staying in the upper 60s.
The heat could impact weekend plans, especially outdoor events and high school sports. City officials in Champaign encourage residents to use cooling centers if needed and check on neighbors vulnerable to heat. Farmers and outdoor workers should plan early starts to avoid the peak afternoon temperatures.
Saturday night remains partly cloudy with mild breezes, but the bigger concern comes with sustained warmth. Air conditioning use is expected to spike, which may strain local power grids. Officials urge residents to conserve energy when possible.
By early next week, conditions ease slightly, but highs will still hold above normal in the low 90s. Cooler fall-like weather appears unlikely before midweek.
Warnings for excessive heat remain possible if temperatures push higher than expected. Updates will be issued if conditions change.
