Severe weather is anticipated to impact several counties in Illinois, prompting the National Weather Service to issue warnings for potential tornadoes, strong winds, and hail. The highest tornado risk is concentrated south of the Kankakee and Illinois River valleys. Chicago is bracing for showers before noon, followed by potentially stronger storms between noon and 3 p.m., with wind gusts reaching up to 40 mph. The most significant threat of severe thunderstorms lies south of Interstate 80, although this could shift northward if the warm front moves further than initially predicted. Residents are urged to stay informed and prepared for rapidly evolving weather conditions.
