Chicago is rolling into Monday with a chilly start but a pretty nice finish on tap. Cool lake air kept things brisk early, with Midway reporting about 52F to kick off the day, but the city is expected to warm into the mid-70s under mostly sunny skies. A breezy west-southwest wind will keep things from feeling too sleepy, with gusts potentially topping 20 mph this afternoon, so count on bright skies and a bit of a blustery edge into the evening.
Midweek Storm Risk
The calm will not last long. Showers and thunderstorms are likely Tuesday, with scattered storms possible from the morning into the late afternoon as gusts pick up across the area. The bigger concern arrives Wednesday, when forecasters say severe thunderstorms — including large hail, damaging winds and possible tornadoes — could impact the region, and heavy rain may trigger localized flash flooding.
According to the National Weather Service Chicago, gusts in and near stronger storms could reach 3025 mph, which could mean messy travel, downed branches and a rough evening commute for some neighborhoods.
Timing And Impacts
On Tuesday, showers should stay scattered and relatively brief for most of the city and suburbs, with many spots only seeing light rainfall totals. The main issue is Wednesday, when a stronger system could bring heavier downpours. Forecasters note that some locations may pick up around 12 inches of rain in a short time, raising the risk of flooded streets, low-lying underpasses filling quickly, and slower commutes.
If you have late-day outdoor plans Wednesday, especially events that run into the afternoon or evening, you may need a backup plan. Transit could move slower than usual, and drivers should be ready for standing water and reduced visibility in bursts of heavy rain.
How To Prepare
Before storms arrive, charge phones, laptops and other devices, secure loose outdoor furniture or decorations that could get tossed around in strong winds, and move vehicles out of low-lying parking spots that tend to flood when heavy rain hits. You can sign up for city emergency alerts and transit notices through NotifyChicago, and it is worth checking updated forecasts before heading to the beaches or evening events midweek.
Bottom line: soak up the mostly sunny, comfortable weather today, keep an eye on Tuesday’s scattered storms, and be ready to pivot plans on Wednesday if severe weather warnings are issued. Local alerts and updated forecasts will be your best guide as this system moves through.
