"Chicago Braces for Multiple Rounds of Severe Storms, Including Hail and Tornadoes"

Multiple rounds of strong to severe storms are expected in the Chicago area, with the potential for hail, tornadoes, and damaging winds. A severe thunderstorm watch has been issued for several counties in Illinois and northwest Indiana. The first round of storms has already occurred, with heavy downpours, lightning, and hail reported. The second round, expected between 12 p.m. and 5 p.m., could be the most damaging, while a third round is expected during the evening commute. The risk of severe storms varies by location, with higher risk in southern areas. Air quality in the region is also poor due to smoke from Canadian wildfires.
