19 of the last 20 years had at least one hail day. The worst was 2008, with 9 hail days and 23 radar detections.
At 3.7 hail days a year this area is very-high frequency for hail. Insurers price hail regionally, and a roof here will see storms — but a radar detection over the tile is not proof your roof was hit.
What this page is, precisely. These counts describe a 0.1° grid tile — roughly 7 miles north to south — containing Sioux City, IA, not a specific address. A detection inside the tile does not prove hail fell on any particular roof, and no detection does not prove none fell. Radar resolution is finest near the radar and coarsens with distance. This is a screening tool, not an insurance claim, a loss report, or an engineering inspection.
