Chicago kicks off Tuesday, May 12, with temperatures climbing to near 77°F — warm and pleasant this morning, but the National Weather Service warns of scattered showers and thunderstorms arriving after 3 PM CT, with wind gusts up to 40 mph. Get your outdoor time in early and know the timeline before you head out.
Today’s Setup
South-southwest winds of 10 to 25 mph are building and will ramp into gusts up to 40 mph this afternoon — classic Windy City conditions. NWS forecasters note a low-confidence window for brief gusts exceeding 45 mph mid-to-late afternoon, though they’ve held the forecast just below Wind Advisory criteria. It’s also a rough day for allergy sufferers: strong winds are moving pollen across the metro in waves, so take your antihistamine before heading to Lincoln Park or along the Lakefront Trail.
Best Window To Be Outside
This morning is your green light. Wrap up errands, outdoor exercise, and yard work before early afternoon. Rain showers are expected around 3 PM CT, with thunderstorms developing shortly after. Most activity should taper off before 10 PM CT, clearing the way for a partly cloudy night.
Rain & Wind Risk
A 50% chance of precipitation plus gusts up to 40 mph makes this a real weather day. The afternoon storm threat isn’t severe, but it’s enough to soak you if you’re unprepared. If you’re commuting or heading out after 3 PM CT, a pair of rain boot shoe covers in your bag will save the day. Blowing dust is also possible in rural areas south of I-80 this afternoon due to seasonal farming activity and recent dry conditions.
White Sox Weather Watch
The Chicago White Sox host the Kansas City Royals at Rate Field today (Tuesday, May 12) — early innings look fine, but expect potential disruptions if the game stretches into late afternoon as storms roll in. Deck out in a Chicago White Sox jersey and a Chicago White Sox fitted cap, and toss a rain layer in your bag. Wednesday’s game (May 13) is the safer weather bet — cooler near 55°F and mostly dry. Get tickets on SeatGeek or Find tickets on StubHub for any game in this three-game series running through May 14.
Concerts This Week
Bring Me The Horizon plays Allstate Arena this Friday, May 15 — indoors, so weather is a complete non-issue. A Bring Me The Horizon hoodie is the perfect call for a late-night show. Also on May 15: Charlie Puth at Rosemont Theatre — another covered indoor venue.
Bruno Mars brings The Romantic Tour to outdoor Soldier Field on Saturday, May 16. NWS forecasters flag May 16–19 as a period that may feature multiple rounds of showers and storms across the Chicago area — keep a close eye on the extended forecast as that weekend approaches.
Dinner Tonight
A pot of pasta or a quick stir-fry is exactly right for a stormy Tuesday evening — warm, easy, and no grill needed. Stock up with Amazon Fresh groceries delivered to your door; you can order groceries on Amazon and skip the trip entirely before the rain arrives.
Next Few Days
Wednesday, May 13: High near 55°F, partly sunny, north-northwest winds 15–20 mph, just a 2% rain chance — a cool, breezy reset after today. Late week: NWS expects a longer-lasting warm-up to build Thursday into Friday. Weekend: The May 16–19 window may bring multiple rounds of showers and storms to the Chicago area. Stay tuned to your Chicago weather forecast as the week unfolds.
