Chicago, Illinois – Dangerous weather conditions are set to impact northern Illinois and northwest Indiana into early week, with thunderstorms, flooding concerns, and hazardous conditions along Lake Michigan beaches.
According to the National Weather Service in Chicago, storms are possible overnight, with the greatest risk west of Rockford. On Monday, storms will intensify across the region, bringing locally heavy rain, gusty winds, and an elevated flooding risk. A Level 1 severe thunderstorm risk is in place, raising concerns for damaging winds and localized downpours that could slow morning and evening commutes.
The heat remains a secondary hazard, with highs in the mid-80s and muggy air pushing heat indices higher. By Tuesday, showers and storms taper, though localized flooding and heat risks linger.
Along Lake Michigan, waves between 3 and 6 feet are expected through Monday morning, creating life-threatening rip currents. Officials urge swimmers to stay out of the water and avoid piers, jetties, and breakwalls.
Residents should prepare for rapidly changing conditions Monday, charge devices, and avoid unnecessary travel during storms. Further advisories may be issued if flooding or severe weather intensifies.
