NEXRAD logged 4 hail signatures up to 1"; the estimated-size surface reached 0.5" aloft. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.

Evidence / storm surfaces
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
This was Yellow Spring's 2nd recorded hail day, arriving 17 days after the Jul 4, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Yellow Spring at 1" — the largest NEXRAD radar signature.
The Jul 21, 2026 convective day was bigger than Yellow Spring: the same system put hail over 703 other tracked cities, 53 of them in West Virginia. Nearest: Augusta (9 miles northwest, up to 1"); Rio (11 miles west, up to 1.25"); Romney (16 miles west, up to 1.25").
These maps are stills. In the app this date is one of 3 Yellow Spring 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
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.
“Multidirectional tree damage... at least dozens of trees. Large trees uprooted... large limbs snapped on the 5100 block of route 23/3 near High View WV... consistent wi (LWX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 56 minutes, from to .
Reports came from Lehew — beyond Yellow Spring itself.
Damage-capable hail signal
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
Potential roof exposure
$828K
Potential roof exposure — 69 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
July 2028
Claims from this storm can typically be filed until around July 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 $14 on top of the $150 plan.
