Springfield, Illinois – Showers and thunderstorms are expected to impact much of central Illinois tonight, with the greatest threat for heavy rainfall coming before midnight. Residents from Springfield to Champaign should prepare for periods of intense rain, raising the risk for localized flooding and difficult travel conditions on major routes including I-72 and I-55.
According to the National Weather Service in Lincoln, areas of heavy rainfall—potentially exceeding 0.75 inches—are possible through the late evening hours, especially in counties south of I-70 and along the I-72 corridor. Probability of significant rain ranges from 40% to 60% in key cities like Springfield, Champaign, and Effingham, with a lower chance in Peoria and Bloomington.
Localized downpours could impact low-lying areas, rural roads, and urban streets, making hydroplaning a risk for drivers. Those commuting tonight are urged to reduce speed, avoid flooded roads, and monitor weather alerts. Power outages are unlikely but possible with stronger thunderstorms. Overnight lows will range from 65° to 73°, and thunderstorm chances will decrease after midnight.
The unsettled pattern continues into Monday and Tuesday with scattered storms and seasonable temperatures. More advisories could follow if rainfall totals increase or additional storms develop.
