How Mason City saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Jun 20, 2026 — this storm produced no NEXRAD point detections over Mason City, so there is one map to show, not two.

What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
Nobody on the ground filed a report over Mason City for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
What 1.75" hail means for Mason City roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
