Clear skies greeted Chicago on Sunday, May 10, 2026, with a brisk 46°F reading at Midway to start the day. Sunshine is set to rule, but a steady east-northeast breeze will keep things feeling cooler near the water, with an official high near 58°F and some gusty afternoon wind in the mix.
Afternoon Winds Pick Up
Expect east-northeast winds around 5 to 15 mph this afternoon, with gusts that could hit 25 mph before easing overnight. It will stay on the breezy side along the lake. The NWS Chicago is also flagging a brief window of elevated brush-fire potential in outlying counties, along with a marginal chance for patchy frost late tonight north of I-88.
Looking ahead, a stronger system is set to roll in on Tuesday, May 12, 2026, bringing a slight chance of morning showers and a more likely round of showers and thunderstorms in the afternoon and evening, with highs near 75°F.

How This Affects Your Plans
If you are heading outside this afternoon, plan on that wind doing some extra work. Secure any lightweight patio furniture and grab a windproof layer, especially if you are walking the lakefront, where it will feel noticeably cooler than inland.
For Tuesday, May 12, 2026, keep plans a bit flexible, particularly for the late day and evening. Those showers and thunderstorms could bring brief heavy downpours, lightning, and gusty winds that may complicate outdoor events or errands. There are currently no watches or warnings in effect for the city, but it is worth monitoring updates if you have anything important scheduled for late Tuesday.
Looking Ahead
High pressure returns Wednesday and Thursday (May 13–14, 2026), bringing seasonable and drier weather with daytime highs in the low 60s. After that, the pattern turns warmer and more unsettled late in the week. Highs climb toward the upper 70s by Friday, with scattered chances for storms over the weekend. Watch for updates if any watches or advisories are issued as that warmer, stormier pattern settles in.
