Chicago weather today is mostly sunny with a high near 49°F, but watch out for patchy frost this morning—bundle up if you’re heading out before 7 AM CT, especially in the outlying areas and near Lincoln Park.

Today is the perfect setup for outdoor plans around the city. High pressure is drifting through the region, keeping conditions dry and stable through the afternoon. Winds will stay light at 5 to 10 mph from the north-northeast, so it won’t feel particularly windy for a Saturday in the Windy City. If you’re catching the Chicago Cubs vs. Arizona Diamondbacks game at Wrigley Field this afternoon, you’ll have mostly sunny skies and comfortable conditions—bring a light jacket and maybe grab a Chicago Cubs fitted cap to shield from the sun. Fans can Find tickets on StubHub if you’re still looking to get in on the action.

The National Weather Service notes that increasing mid- and upper-level cloud cover will move in tonight, preventing another frost event tomorrow morning. That’s good news because Sunday will see temperatures climbing to near 66°F—a noticeable warmup—but rain showers are expected between 7 AM and 4 PM CT as an upper-level shortwave moves through. There’s a 40% chance of precipitation, with southwest winds gusting as high as 35 mph. The Chicago Cubs vs. Arizona Diamondbacks game tomorrow at Wrigley and the Chicago Fire FC vs. FC Cincinnati match at Soldier Field will both need to contend with those showers and gusty winds.

If you’re planning any yard work or outdoor projects, today is your window. The dry conditions and light winds make Saturday ideal for mowing, grilling, or even tackling that spring cleanup around your Lincoln Park or North Shore neighborhood. Just keep an eye on the wind gusts ramping up this evening—anything loose should be secured.

Looking ahead, Monday night brings a 30–50% chance of thunderstorms, with the National Weather Service noting that a few could become strong to severe, primarily near and south of I-80. After that system moves through, expect near to below-normal temperatures to settle in through next weekend with occasional rain chances. It’s a typical Chicago spring pattern—one warm day followed by cooler, wetter conditions.

For tonight’s dinner, consider a hearty pasta or stir-fry that pairs well with the cool evening temperatures. You can order groceries on Amazon and have everything you need delivered, including fresh vegetables and sauce ingredients to round out your meal.
