Two rounds of storms are forecast to sweep through Illinois on Sunday, according to the National Weather Service. The first round, expected to move out of the area by 1 p.m., could bring downpours, lightning, and gusty winds. The second round, anticipated to develop after 4 p.m. and continue into the evening, may be more severe, with damaging winds, hail, and potential tornadoes. However, if the initial storms persist into the early afternoon, the severe weather threat is likely to diminish and shift farther south later in the day.
