Evidence / storm surfaces
How Wilmington saw the hail — from two instruments
Aug 11, 2026 · Wilmington, OH
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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
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 Wilmington's hail record.
This was Wilmington's 6th recorded hail day, arriving 1 day after the Aug 10, 2026 storm. By severity it ranks 5th of the 8 storms we have logged here. Radar put the day's largest stone over Wilmington at 0.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Wilmington: the same system put hail over 1,041 other tracked cities, 92 of them in Ohio. Nearest: Waynesville (11 miles west, up to 0.75"); New Vienna (15 miles south, up to 0.5"); Oregonia (17 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 8 Wilmington storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
Ground reports
What people on the ground reported
1 report filed with the NWS
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.
Wind reports
1 reportBelow the severe threshold
What 0.5" hail means for Wilmington 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.

Potential roof exposure — 84 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 5, 2026.
