Chicago, IL – Chicago residents can expect a gradual warmup this week, with temperatures reaching the lower 70s before chances of rain return ahead of Halloween. The changing forecast could affect outdoor celebrations across Chicago and Cook County, while daylight saving time ends Sunday, November 1.
According to the National Weather Service in Chicago, Monday, October 26, will bring mostly cloudy skies and a high near 60 degrees. North northeast winds of 10 to 15 mph could produce gusts reaching 20 mph.
Monday night remains mostly cloudy, with temperatures dropping to approximately 52 degrees.
Tuesday, October 27, brings another mostly cloudy day, although temperatures will climb to around 65 degrees. Southeast winds could gust as high as 20 mph before easing overnight.
Wednesday, October 28, marks the beginning of a warmer stretch, with partly sunny skies and an afternoon high near 70 degrees. Overnight temperatures should remain relatively mild, falling to around 57 degrees.
Thursday, October 29, is expected to be the warmest day of the week, with temperatures reaching approximately 73 degrees. A chance of showers develops before 1 p.m., although partly sunny conditions are also expected.
Friday, October 30, brings partly sunny skies and a high near 69 degrees. Another chance of showers develops Friday night as temperatures fall to around 56 degrees.
Halloween on Saturday, October 31, could bring additional showers, with mostly cloudy skies and a high near 68 degrees.
Families planning trick or treating, neighborhood celebrations or other outdoor activities should monitor updated forecasts as the weekend approaches. The National Weather Service has not specified a precipitation percentage or exact timing for Saturday's showers in the provided forecast.
Sunday, November 1, remains mostly cloudy with another chance of showers and a high near 67 degrees.
Daylight saving time ends Sunday at 2 a.m., when clocks move backward one hour to 1 a.m., giving residents an extra hour overnight.
For Chicago and surrounding Cook County communities, the main weather concern is the return of showers heading into Halloween weekend rather than a significant temperature drop.
