Chicago woke up Sunday, May 31, to one of those classic “do I need a jacket or not?” mornings, with cool, partly sunny skies and temperatures in the upper 50s. Afternoon highs are expected to top out near 68°F, with a mix of sun and clouds and a bit of a breeze picking up along the lakeshore later in the day.
Tonight And Monday Morning
Late tonight into early Monday, June 1, a weak disturbance could squeeze out some isolated, very light rain or sprinkles, mainly after 1 a.m., but most neighborhoods should stay dry. Overnight lows will slide into the mid to upper 50s, with north-northeast winds around 5–10 mph. The bottom line for Monday’s commute: little to no impact expected.
Late-Week Warmup
The workweek stays mostly dry through midweek before a serious warm-up arrives Thursday and Friday. Highs climb into the upper 60s on Tuesday, then the mid 70s on Wednesday, and are forecast to jump into the upper 80s by Thursday and Friday, June 4–5. According to NWS Chicago, Friday into the weekend is the next solid window for showers and thunderstorms, so if you have outdoor plans Friday night or on Saturday, June 6, you may want to keep them a bit flexible.
Lakefront Versus Inland
If you are near the lake, expect to feel it. Lakeshore neighborhoods will run a few degrees cooler than inland areas, especially during the afternoon when lake breezes kick in. That likely means 60s near the water while spots farther inland warm up faster. Light east-to-northeast breezes will be common through Monday, gradually turning more southerly as the warmer air surges in later in the week.
Quick Take
Plan on a light jacket for Monday morning and sunscreen by midweek. Layers will be your best friend as temperatures swing from springlike to almost summer-ready. And if you are banking on dry skies Friday night or this weekend, keep an eye on updated forecasts in case those showers or thunderstorms decide to roll through.
