Saturday is forecast to be mostly sunny. The afternoon high is forecast near 68 degrees. South-southeast winds of 5 to 10 mph are expected.

Sunday Brings the Weekend’s Warmest Weather

Saturday night is expected to be partly cloudy, with a low around 52 degrees. Sunday should be mostly sunny and warmer, topping out near 72 degrees with light south winds.

A Cooler Monday, Then a Mostly Dry Week

A weak cold front is forecast to pass through Monday. Partly sunny skies and a high near 63 degrees are expected. Monday night should be mostly cloudy, with a low around 51.

Tuesday’s forecast calls for mostly cloudy skies and a high near 64 degrees. Temperatures are expected to rise to around 70 Wednesday and 68 Thursday. The week is expected to be generally dry; no weather advisories are currently listed for the area.

For seasonal perspective, NBC Chicago, citing the National Weather Service, places the usual first-freeze window for Chicago and the immediate suburbs between Oct. 27 and Nov. 5. That typical window does not mean freezing temperatures are forecast this week. In a separate Chicago-area forecast from Oct. 6, 2022, the WGN-TV Weather Team described temperatures climbing into the lower 70s before a cold front, then falling after it passed; that was a past forecast, not a prediction for this weekend.
