The National Weather Service reports that several intense supercell thunderstorms moved across northern Illinois on Tuesday, March 10, 2026.
One supercell was responsible for at least four tornadoes across Livingston and Kankakee counties in Illinois, and Newton, Jasper and Starke counties in northwestern Indiana.
Two people were reportedly killed in Indiana.
A hailstone with a diameter of 6 inches was measured in Kankakee, Illinois.
The National Weather Service says the 6-inch hailstone may be considered for a new Illinois state record. The previous record was a hailstone measuring 4.75 inches in diameter that fell in Minooka in June 2015.
Another supercell moved across the southern and western Chicago metropolitan area and dropped hail ranging in size from 2 to 4 inches in diameter across Bolingbrook, Woodridge, Downers Grove, Westmont and Darien.
