Scattered thunderstorms are expected to move through central and southeast Illinois tonight, bringing with them the potential for heavy rain and gusty winds. This weather system precedes a cooler air mass that will arrive midweek, offering a welcome respite from the current humidity. Residents should be aware that storms arriving late this evening may lead to brief flooding in low-lying areas. Motorists traveling on I-55 and I-72 should anticipate potential traffic delays due to reduced visibility and ponding on roadways.
