Questions
What date did hail last hit Gregory County?
May 17, 2026, per the NWS Storm Events record. The largest since 2016 was 2.75" (baseball) on August 25, 2024.
Does a county record prove hail at my house?
No. NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure. The free check above shows what was recorded near your specific address, with distances.
