Chicago is under a flood watch today with a 100% chance of severe thunderstorms, a high near 68°F, and a real risk of damaging winds and large hail — take this forecast seriously and limit your outdoor time this afternoon.
Today’s Setup
This is one of the most dangerous mid-June setups Chicagoland has seen in years. The National Weather Service and the Weather Prediction Center have both flagged the area for a Moderate Risk of excessive rainfall, with a flood watch currently in effect. A deep, rapidly moving low-pressure system is racing northeast across the Great Lakes, dragging a potent cold front behind it. Rain showers arrive around 8 AM CT, then organized severe thunderstorm clusters take over from roughly 11 AM through 4 PM CT, with activity continuing into the early evening. Total rainfall between 2 and 3 inches is possible, with localized rates near 2 inches per hour where storms overlap and backbuild. South winds gust to 35 mph ahead of the front.
Severe Weather Risk
The NWS office in Romeoville warns of an outbreak potential — damaging tornadoes, destructive straight-line winds, and large hail are all on the table this afternoon and early evening. If your car is parked outside, a hail protection car cover is worth getting on it now — hail can arrive with almost no warning in these storm types. Keep NOAA alerts active on your phone and know your shelter options whether you’re in the Loop, Lincoln Park, or the northern suburbs.
Events: Know Before You Go
The Strokes play the United Center tonight (June 17) — the arena is covered, so the show goes on, but driving through flooded Chicago streets is another matter entirely. Leave early and give yourself extra time. Snag a The Strokes t-shirt to mark the night, and if you still need seats, Find tickets on StubHub before the afternoon storm window hits.
The Chicago Cubs host the Colorado Rockies at Wrigley Field today (June 17), but this game faces a serious weather challenge with thunderstorms likely most of the day. Watch for postponement news before heading to Wrigleyville. If you’re a die-hard who’s going regardless, a Chicago Cubs fitted cap and a packable rain jacket are non-negotiable.
What to Bring
A compact travel umbrella belongs in your bag today no matter where you’re headed — winds are gusty enough that a cheap one will fold inside out. Check our outdoor gear deals for other storm-season essentials.
Next Few Days
Thursday is the payoff: mostly sunny with a high near 74°F and northwest winds at 10 to 20 mph. The Cubs homestand rolls on at Wrigley (Colorado Rockies on June 18, then Toronto Blue Jays June 19–20) in near-ideal conditions. Thursday night, Carín León brings his De Sonora Para El Mundo Tour 2026 to Allstate Arena — a great evening to be out. Get tickets on SeatGeek while they last.
The weekend brings another storm system. The National Weather Service is already flagging potential showers and possibly severe weather by Saturday or Sunday — critical timing for outdoor events like Morgan Wallen with Brooks and Dunn at Soldier Field on June 19, and ROSALÍA: LUX TOUR 2026 at the United Center on June 20. Keep the Chicago weather forecast bookmarked as confidence in the timing builds.
Tonight’s Dinner
Today calls for slow cooker chili or a hearty beef stew. Load your programmable slow cooker before you head out this morning and come home to something warm and ready. An enameled cast iron Dutch oven works beautifully on the stovetop for a big pot of soup. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Stay safe today, Chicago — this storm is the real deal.
