Chicago wakes up under a smoky haze this Monday with temperatures climbing to a high near 84°F, and while the day starts mostly dry, the National Weather Service in Romeoville is watching a batch of storms tracking down from Minnesota that could clip the area later on.

Today’s Setup

mornings smoke gives way to a partly sunny afternoon, with isolated showers and thunderstorms possible between 10 AM and 1 PM CT. Winds run 5 to 15 mph out of the south-southwest, gusting to 25 mph. Overnight lows only dip to around 74°F, and NWS forecasters say scattered storms are more likely after 7 PM CT, with a 50% chance of showers and thunderstorms and gusts up to 30 mph.

Best Window To Be Outside

If you’re headed to Grant Park, the Lakefront Trail, or a round at one of the Chicago Park District courses, late morning through early afternoon is your best bet before the midday storm risk ticks up. It’s genuinely good golf weather today — warm, breezy, and mostly dry until early afternoon.

Storms, Wind, And Smoke: What The Forecast Discussion Says

According to this morning’s Area Forecast Discussion, forecasters have been tracking a cluster of storms moving out of Minnesota toward Iowa, driven by an elevated mixed layer and a low-level jet. The key message: there’s still a severe weather threat today, but current thinking is much of the Chicago area may be missed as the activity tracks south. No SPC severe outlook is in place for our area right now. A series of cold fronts will bring cooler temperatures by midweek, so enjoy today’s warmth while it lasts. The lingering smoke aloft may also mean hazy skies and reduced visibility at times — those with respiratory sensitivities should keep outdoor exertion light.

What To Wear Or Bring

Humidity and warmth make this a sweat-through-your-shirt kind of day — a cooling neck towel is worth tossing in your bag for the ballpark or the trail. Wind gusts near 25-30 mph mean patio umbrellas and loose lawn chairs should be secured before tonight’s storms roll in.

Cubs Homestand, RUSH At United Center, And This Week’s Events

The Chicago Cubs open a three-game series against the Detroit Tigers at Wrigley Field starting Tuesday, July 21, running through Wednesday, July 23 — Tuesday’s forecast calls for a high near 84°F with scattered storms and gusty west-northwest winds, so day-of-game tailgaters should keep an eye on the radar. Find tickets on SeatGeek or Find tickets on StubHub, and gear up with a Chicago Cubs jersey or a Chicago Cubs fitted cap. Tonight, the RUSH: Fifty Something concert hits United Center — indoor, so the storm chance won’t be a factor for the show itself, though commuters should plan for wet roads if storms fire up after 7 PM. Heading to the Salt Shed Wednesday for KALEO with Dawes? Same story — check radar before you leave.

Dinner Tonight

With warm, breezy conditions before tonight’s storms, it’s a solid grilling window — burgers, steaks, or grilled chicken with corn on the cob all work well. Grab an instant-read meat thermometer and a grill brush and scraper set to keep things easy. If the smoky haze has you thinking low-and-slow instead, our smoke tri-tip pellet grill guide is worth a look. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Expect a warm, unsettled stretch through Tuesday with scattered storm chances both days, then cooler air moves in by midweek behind a series of cold fronts, per NWS forecasters. For more outdoor gear ideas as the pattern shifts, browse outdoor gear deals.
