Evidence / storm surfaces
How Sonora saw the hail — from two instruments
May 21, 2026 · Sonora, TX
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
1.25"
Only the radar-estimated size surface resolved for May 21, 2026 — this storm produced no NEXRAD point detections over Sonora, so there is one map to show, not two.
The storm in context
Where May 21, 2026 sits in Sonora's hail record.
This was Sonora's 10th recorded hail day, arriving 1 day after the May 20, 2026 storm. By severity it ranks 7th of the 16 storms we have logged here. Radar put the day's largest stone over Sonora at 1.25" — radar-estimated size aloft.
The May 21, 2026 convective day was bigger than Sonora: the same system put hail over 120 other tracked cities, 33 of them in Texas. Nearest: Junction (30 miles east, up to 0.75"); Rocksprings (45 miles south, up to 1"); Menard (52 miles northeast, up to 0.75").
These maps are stills. In the app this date is one of 16 Sonora 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.

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.
Hail reports
1 reportDamage-capable hail signal
What 1.25" hail means for Sonora 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.
2,473 homes × $12,000 avg. claim
Potential roof exposure
$30M
Potential roof exposure — 2,473 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 2,473 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
May 2028
Claims from this storm can typically be filed until around May 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.
