Chicago started the day on the brisk side, with morning temps sitting in the mid‑50s. By afternoon, though, the city will trade light layers for sunglasses as sunshine helps push highs to around 72°F. Light east‑southeast breezes will keep things comfortable for most outdoor plans away from the immediate lakeshore. The real plot twist comes later in the week, with a sharp warmup Thursday and storm chances returning Friday into Saturday.
Afternoon And Tonight
Skies stay mostly sunny this afternoon with a high near 72°F and gentle east‑southeast winds around 0–10 mph. Humidity will stay relatively low away from the lake, which should make it feel pleasant rather than sticky. Tonight, clouds increase a bit, with partly cloudy skies and a low near 64°F and southeast winds around 5–10 mph, according to the National Weather Service.
Plan Ahead
If you are tackling errands, walking the dog or heading to a neighborhood event, today is a good window to do it in comfort. As winds pick up later this week, it is a smart move to secure lightweight items that could get tossed around. Residents who are sensitive to heat or who need a cooler place to be can look for public cooling options, including designated sites listed by the city. Call 311 or check local listings for details on hours and locations. For a central roundup of options, visit the Chicago Park District.
Thursday Warmup, Fire Risk And Weekend Storms
By Thursday, Chicago trades the light jacket weather for near‑summer heat. Southwesterly winds will push temperatures into the upper 80s, with a high near 88°F and gusts up to about 25 mph. Afternoon relative humidity is expected to drop into the mid‑20s, and that combination of warm, dry and occasionally breezy conditions could lead to an elevated fire danger in dry grass and brush. Fire officials want people to avoid open burning and stick closely to local fire safety guidance.
Things turn more unsettled Friday into Saturday. The best shot at showers and thunderstorms arrives Friday afternoon into Friday night, with a risk of brief heavy rain and gusty winds before conditions trend drier again on Sunday, according to the National Weather Service.
