Chicago is headed into a warm, breezy Saturday, with clear skies early, afternoon temperatures near 77 degrees and wind gusts up to 25 mph. The city stays dry today, but the forecast takes a sharper turn from summerlike warmth to storm chances and cooler air by next weekend.

Warm Saturday Gives Way To Sunny Sunday

Saturday will be partly sunny with south-southeast winds of 10 to 15 mph, while temperatures ease back into the mid-70s late in the afternoon. Tonight, lows will be in the 50s for most areas, with only a low chance of showers in northwest Indiana, followed by a sunny Sunday with a high near 72, according to the National Weather Service.

Monday Could Feel Like Summer Again

Monday is shaping up as the warmest day of the stretch, with mostly sunny skies and highs in the lower to mid-80s across the area. Southwest winds could gust between 20 and 30 mph, and the National Weather Service says temperatures may come close to record highs for October 12.

A Cold Front Approaches Early Tuesday

The warm spell comes with a catch: precipitation chances are fairly low around the cold front’s passage early Tuesday. A few showers and possibly thunderstorms may accompany the front as it moves through.

Cooler, More Unsettled Weather Arrives Later

Showers and thunderstorms remain possible Wednesday and Thursday, when highs are expected to stay in the 60s. Colder air is expected to arrive into the following weekend.

No watches, warnings or advisories are listed for the Chicago area in the current forecast.
