Why it matters

This page holds every NOAA-documented hail and severe wind event in St. Clair County, Illinois from 2016 to 2025. St. Clair County has logged 55 hail events in that time, 11 of them at 1.75″ (golf-ball) or larger, the size that routinely qualifies a roof for an insurance claim. Add 98 severe thunderstorm-wind events topping out at 87 mph, and most homes in the county have a documented weather event inside the typical carrier filing window. In Curbsight, a hail-hit roof shows up with its storm date already on the card, so nobody cross-references storm records by hand.
