Questions
What date did hail last hit Knox County?
August 15, 2024, per the NWS Storm Events record. The largest since 2016 was 1.75" (golf ball) on June 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.
