Friday, July 24 started on a friendly note in Chicago, with partly cloudy skies, temps in the mid 60s, and a light south-southeast breeze. The afternoon is set to turn mostly sunny with a high near 77°F and noticeably lower humidity than a typical late July day. If you have outdoor plans, this is the stretch to cash in on, because the comfortable air will not stick around for the weekend.
Afternoon And Evening
Clouds should thin out from northwest to southeast this afternoon, and while some high-level wildfire smoke may drift across the region, it is expected to stay mainly overhead rather than at ground level. There is a very small chance of a few sprinkles this morning near and just south of the I-80 corridor, but otherwise winds will stay light at around 0 to 10 mph, and evening lows will slide back to the mid 60s.
The result is a largely dry, easygoing afternoon and evening commute for most neighborhoods, with comfortable air that will feel like a bit of a bonus round for late July.
Weekend Outlook
The break ends quickly. Heat and humidity start building back into the region Sunday and carry into Monday, with inland neighborhoods expected to feel it the most. According to the National Weather Service Chicago, highs should climb into the upper 80s to around 90°F on Sunday and into the low 90s on Monday.
Heat index values could push well into the 90s and top 100°F in some spots, and local heat headlines may be needed if those numbers hold. If you are planning barbecues, ball games, or outdoor events later this weekend, it is worth keeping an eye on forecast updates and being ready to tweak the timing or move things indoors.
How To Stay Cool
If the weekend heat starts to mess with your plans, the city operates daytime cooling centers along with other air-conditioned public spaces. You can call 311 or use the city map to find the closest option.
Basic playbook: bring water, avoid strenuous outdoor activity during the hottest part of the day, and check in on elderly or medically vulnerable neighbors who may not have reliable air conditioning. For an official list of sites, see the cooling center map from the City of Chicago.
Bottom line: enjoy the rare comfortable Friday while it lasts, then get ready for a fast flip to hot and humid conditions Sunday and Monday, and be prepared to adjust outdoor plans if heat headlines are issued.
