Evidence / storm surfaces
How Sonora saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for May 20, 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 20, 2026 sits in Sonora's hail record.
This was Sonora's 9th recorded hail day, arriving 1 day after the May 19, 2026 storm. By severity it ranks 6th of the 16 storms we have logged here. Radar put the day's largest stone over Sonora at 1.75" — radar-estimated size aloft.
The May 20, 2026 convective day was bigger than Sonora: the same system put hail over 109 other tracked cities, 24 of them in Texas. Nearest: Fort Mc Kavett (30 miles northeast, up to 1.75"); Junction (30 miles east, up to 1"); Eldorado (35 miles north, up to 1.75").
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.
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 Sonora 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.
High damage potential
What 1.75" hail means for Sonora roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.6M
Potential roof exposure — 383 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 383 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.
Names and phones for every home in the footprint: at most $80 on top of the $150 plan.
