What initially looked like a discarded gallon jug in a roadside ditch turned out to be a record-breaking hailstone, now confirmed as the largest ever documented in Texas at roughly 18 cm (7.1 inches). It was discovered near Vigo Park in Swisher County by storm chaser Val Castor and his associates on June 2, 2024. They clicked several pictures of the hailstone alongside objects to provide a visual reference of size and submitted them to the Insurance Institute for Business and Home Safety (IBHS). The size of the hailstone was determined using photogrammetry and AI analysis along with the estimates from the storm chasers.
