Evidence / storm surfaces
How Cincinnati saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Aug 11, 2026 sits in Cincinnati's hail record.
This was Cincinnati's 5th recorded hail day, arriving 4 days after the Aug 7, 2026 storm. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Cincinnati at 0.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Cincinnati: the same system put hail over 1,041 other tracked cities, 92 of them in Ohio. Nearest: Harrison (11 miles west, up to 0.5"); Hamilton (14 miles north, up to 0.5"); Florence (15 miles south, up to 0.5").

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.
Nobody on the ground filed a report over Cincinnati 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.
Below the severe threshold
What 0.5" hail means for Cincinnati roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$156M
Potential roof exposure — 13,025 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 65 jobs
- Illustrative work
- ~$975K
Close just 0.5% of the 13,025 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
August 2028
Claims from this storm can typically be filed until around August 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 $2,735 on top of the $150 plan.
