Springfield, Illinois – Thunderstorms will linger across central and southeast Illinois this week, with hot, humid air and a daily risk of strong storms keeping residents on alert. Roads and outdoor plans could be impacted as each afternoon brings scattered thunderstorm development, with highs climbing to 90°F through Saturday.
According to the National Weather Service in Lincoln, isolated storms could pop up each day, but the highest risk for severe weather will arrive Friday. Storms may bring gusty winds, brief downpours, and lightning, mainly during the late afternoon and evening hours. Overnight lows will hover in the upper 60s to low 70s.
Cities from Decatur to Effingham, and along I-72, should watch for quick changes in weather conditions, especially Friday. Localized power outages and ponding on roadways are possible. Residents are urged to keep devices charged, avoid outdoor activities during storms, and drive cautiously if heavy rain develops.
This weather pattern marks one of the first prolonged stretches of daily storms this summer, making travel and outdoor events more unpredictable.
