Chicago is currently under a flood watch due to persistent severe weather conditions, including multiple rounds of showers and thunderstorms expected through late Wednesday night. The National Weather Service has issued warnings for potential flash flooding, especially in areas with poor drainage, as recent heavy rainfall has already saturated the soil. The severe weather brings threats of damaging winds up to 70 mph and large hail, potentially as large as half-dollars. The flood watch covers several Illinois counties, including Cook, Lake, and Will, as well as parts of northwest Indiana.
