Evidence / storm surfaces
How Black Rock saw the hail — from two instruments
Aug 22, 2026 · Black Rock, AR
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-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.
Max size
1"
Only the radar-estimated size surface resolved for Aug 22, 2026 — this storm produced no NEXRAD point detections over Black Rock, so there is one map to show, not two.
The storm in context
Where Aug 22, 2026 sits in Black Rock's hail record.
This was Black Rock's 5th recorded hail day, arriving 32 days after the Jul 21, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Black Rock at 1" — radar-estimated size aloft.
The Aug 22, 2026 convective day was bigger than Black Rock: the same system put hail over 501 other tracked cities, 76 of them in Arkansas. Nearest: Ravenden (11 miles northwest, up to 1"); Hoxie (11 miles southeast, up to 0.75"); Pocahontas (11 miles northeast, up to 0.75").

Damage-capable hail signal
What 1" hail means for Black Rock roofs.
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
What this storm is worth to a roofer.
2,363 homes × $12,000 avg. claim
Potential roof exposure
$28M
Potential roof exposure — 2,363 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 2,363 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.

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 Aug 23, 2026.
