Evidence / storm surfaces
How Dayton 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.
Estimated size field 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 16, 2026 — this storm produced no NEXRAD point detections over Dayton, so there is one map to show, not two.
The storm in context
Where Jun 16, 2026 sits in Dayton's hail record.
This was Dayton's 2nd recorded hail day, arriving 54 days after the Apr 23, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Dayton at 0.75" — radar-estimated size aloft.
The Jun 16, 2026 convective day was bigger than Dayton: the same system put hail over 225 other tracked cities, 58 of them in Iowa. Nearest: Stratford (5 miles east, up to 0.75"); Otho (9 miles northwest, up to 1"); Pilot Mound (9 miles southwest, up to 0.75").

Ground reports
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.
The National Weather Service logged no spotter reports for this storm over Dayton. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Near the severe threshold
What 0.75" hail means for Dayton roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$26M
Potential roof exposure — 2,150 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 11 jobs
- Illustrative work
- ~$165K
Close just 0.5% of the 2,150 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
June 2028
Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $452 on top of the $150 plan.
