Hail in Sonora · May 19, 2026
The estimated-size surface reached 2" aloft; NEXRAD logged no point detections over Sonora that day. At 2" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

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 19, 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 19, 2026 sits in Sonora's hail record.
This was Sonora's 8th recorded hail day, arriving 9 days after the May 10, 2026 storm. By severity it ranks 3rd of the 16 storms we have logged here. Radar put the day's largest stone over Sonora at 2" — radar-estimated size aloft.
The May 19, 2026 convective day was bigger than Sonora: the same system put hail over 263 other tracked cities, 151 of them in Texas. Nearest: Junction (30 miles east, up to 2"); Eldorado (35 miles north, up to 1.25"); Christoval (45 miles north, up to 1.25").
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.
Severe hail signal
What 2" hail means for Sonora roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$33M
Potential roof exposure — 2,714 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 14 jobs
- Illustrative work
- ~$210K
Close just 0.5% of the 2,714 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 $570 on top of the $150 plan.
