Chicago weather today brings unseasonably cool conditions with a high near 45°F and a slight chance of rain showers after 3 PM CT, according to the National Weather Service.
This afternoon will feel more like early April than early May. Temperatures are actually expected to fall through the afternoon—dropping to around 43°F by evening—thanks to cold air advection from the north northeast. Winds will gust as high as 20 mph, so if you’re heading to Wrigley Field for the Chicago Cubs vs. Arizona Diamondbacks game today, bring a jacket and consider grabbing a Chicago Cubs fitted cap to keep the wind from messing with your hair. The rain chance is only 18 percent, so you likely won’t need a packable rain jacket, but the National Weather Service notes that isolated showers could redevelop this afternoon, especially near Lake Michigan where lake-breeze convergence may trigger a few sprinkles.
Tonight will be even colder. Skies should clear out as the system departs, and the National Weather Service Area Forecast Discussion warns of frost development across the region. Temperatures will dip into the low to mid 30s overnight—so if you have tender plants or a garden in Lincoln Park or along the North Shore, now’s the time to cover them up. Light winds (5 to 10 mph) will allow for efficient radiational cooling.
The good news? Saturday looks fantastic. Mostly sunny skies and a high near 48°F will make for a beautiful day to explore Millennium Park or catch the Chicago Cubs vs. Arizona Diamondbacks game at Wrigley Field on Saturday. You might even want to grab a Chicago Cubs jersey to show your support in the stands. If you’re planning to Get tickets on SeatGeek or Find tickets on StubHub, Saturday’s conditions will be ideal for baseball—no rain expected and calm northeast winds at 5 to 10 mph.
Sunday warms up nicely to 63°F, but the National Weather Service mentions a low (15–25 percent) chance of thunderstorms late in the day as another system approaches. That’s also game day for the Chicago Fire FC vs. FC Cincinnati match at Soldier Field, so monitor conditions if you’re heading out. By Monday, there’s a better (30–40 percent) chance for thunderstorms, and temperatures will remain near to below normal through the rest of next week.
For tonight’s dinner, embrace the chill with comfort food. A hearty slow-cooker chili or beef stew pairs perfectly with this cool weather—set it in the morning and come home to a warm meal. You can order groceries on Amazon and pick up everything you need for a programmable slow cooker meal, or invest in an enameled cast iron Dutch oven for stovetop cooking. Either way, you’ll have dinner ready without heating up the kitchen.
Weekend outlook: Saturday is your best day—mostly sunny and pleasant. Sunday warms to 63°F but watch for late-day storms. Keep an eye on Monday’s thunderstorm chances as the week ahead stays cool and unsettled.
