Chicago, Illinois – Strong thunderstorms could roll through parts of northern Illinois by Tuesday afternoon, bringing gusty winds and heavy rain south of the I-80 corridor, especially between La Salle and Rensselaer.
According to the National Weather Service in Chicago, scattered thunderstorms may become strong or severe late Tuesday, with the highest threat focused south of the I-80 line. Rain and drizzle are expected to continue overnight and through Wednesday, particularly north of I-80, keeping roads slick and visibility low during morning commutes.
Windy conditions could further impact travel Tuesday, with gusts adding to the storm’s severity. Cities including Joliet, Kankakee, and Ottawa should prepare for the potential of localized flooding and hazardous driving conditions.
