Chicago, IL – A noticeable cooldown will arrive across the Chicago area Monday, Oct. 26, following a mild weekend that could bring afternoon temperatures into the lower 70s. Sunday's expected high near 72 degrees will give way to temperatures around 65 degrees Monday, with additional cooling Tuesday as clouds become more widespread. The gradual transition will mark a change from the weekend's comfortable autumn conditions, although temperatures are expected to remain well above freezing throughout the available forecast period.
According to the National Weather Service in Chicago, Monday will bring partly sunny skies and a high near 65 degrees, approximately 7 degrees below Sunday's expected afternoon high. Mostly cloudy conditions are forecast Monday night, with temperatures falling to around 52 degrees. The cooler pattern continues Tuesday, when highs are expected to reach approximately 63 degrees under mostly cloudy skies.
Weekend Warmth Peaks Before Monday's Cooldown Friday, Oct. 23, begins a stretch of generally pleasant weather across Chicago, with sunny skies and an afternoon high near 68 degrees. South southeast winds around 5 mph will accompany the sunshine, while partly cloudy conditions Friday night allow temperatures to fall to approximately 51 degrees.
Saturday, Oct. 24, will bring partly sunny skies and another high near 68 degrees. South winds of 5 to 10 mph are expected during the afternoon, followed by partly cloudy skies and a low near 53 degrees Saturday night. These conditions should provide favorable weather for outdoor activities throughout much of the weekend.
Sunday, Oct. 25, is expected to be the warmest day of the forecast period, with mostly sunny skies and temperatures reaching approximately 72 degrees. South southwest winds around 5 mph will accompany the afternoon warmth. By Sunday night, temperatures fall to around 54 degrees as partly cloudy conditions develop ahead of Monday's cooler weather.
Cooler Temperatures Bring a Different Feel to Chicago The change becomes more noticeable Monday, when afternoon temperatures are expected to remain near 65 degrees. Although the decline from Sunday's high is relatively modest, increasing cloud cover may make outdoor conditions feel different from the preceding sunny weekend.
Residents traveling Interstate 90, Interstate 94, Interstate 290 and Interstate 55 should encounter generally favorable weather based on the supplied forecast. No precipitation is indicated through Tuesday, and the forecast does not identify weather related road closures or widespread travel disruptions.
The cooler conditions may be most noticeable for residents spending extended periods outdoors during the afternoon and evening. Monday night's low near 52 degrees will be followed by Tuesday's high around 63 degrees, continuing the gradual temperature decline. Tuesday night remains mostly cloudy, with temperatures falling to approximately 51 degrees.
Temperatures Recover During the Middle of Next Week By Wednesday, Oct. 28, temperatures are expected to recover slightly, reaching approximately 67 degrees under partly sunny skies. Wednesday night brings partly cloudy conditions and a low near 53 degrees.
Thursday, Oct. 29, continues the mild pattern, with mostly sunny skies and another high near 67 degrees. The supplied forecast does not indicate a significant storm system, freezing temperatures or measurable precipitation through Thursday.
The overall outlook suggests a relatively stable autumn weather pattern across Chicago, with a brief cooldown early next week followed by temperatures returning to the upper 60s.
