CHICAGO, IL – Showers taper off across northern Illinois today as a cooler, calmer stretch of fall weather settles in through Thursday. Morning commuters may face wet pavement on I-55 and local arterials, but skies will clear steadily through the day.
According to the National Weather Service Chicago/Romeoville office, isolated thunderstorms remain possible early Tuesday before high pressure builds across the region. Winds shift north at 10–15 mph, gusting to 20 mph, helping drier air move in. Travelers should remain cautious during early rush hour as light rainfall may reduce visibility.
By Thursday, October 9, expect mostly sunny skies and highs near 63°F — ideal for outdoor chores, leaf viewing, or early Halloween decorating. Wednesday brings a brief warm-up with highs around 81°F, followed by a return to crisp, classic October air by the weekend.
Friday and Saturday stay bright and comfortable, with daytime highs in the upper 60s and cool, pleasant evenings in the 40s. Columbus Day (Monday) looks mild near 74°F, a great finish to the first full week of October.
Residents can look forward to several dry, sunny days — perfect for fall markets and pumpkin patch trips before the next potential system moves in next week.
