US · Published Sep 3, 2026
Illinois has set a new state record for the largest hailstone, measured at 6.6 inches in length and weighing 1.228 pounds, following a severe thunderstorm in Kankakee on March 10, 2026 (NOAA, 2026-09-02).
This hailstone surpasses the previous record of 4.75 inches set in 2015 near Minooka, Illinois.

Impact & Risks

The record-breaking hailstone highlights the severity of the March 10 supercell storm, which caused significant damage in Kankakee and surrounding areas. The storm also produced 12 tornadoes, including a destructive EF3 tornado that traveled 36 miles through Kankakee and Aroma Park, Illinois. The state has experienced an unprecedented number of tornadoes in 2026, with 210 confirmed so far, far exceeding the annual average of 66 and nearing the U.S. state record of 244 set by Texas. These extreme weather events underscore the increasing risks posed by severe storms in the region.
