Radar-confirmed hail footprints, opened over Gregory County. Drag to follow a storm across county lines; the map is the whole country. A county with no footprint drawn has no radar-confirmed swath on record yet, and its 58 NOAA events still stand.
This page holds every NOAA-documented hail and severe wind event in Gregory County, South Dakota from 2016 to 2025. Gregory County has logged 58 hail events in that time, 17 of them at 1.75″ (golf-ball) or larger, the size that routinely qualifies a roof for an insurance claim. Add 51 severe thunderstorm-wind events topping out at 88 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.
