Evidence / storm surfaces

How Sonora saw the hail — from two instruments

Sep 4, 2026 · Sonora, TX

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-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Sonora, TX on Sep 4, 2026 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.

Max size 1.25"

Only the radar-estimated size surface resolved for Sep 4, 2026 — this storm produced no NEXRAD point detections over Sonora, so there is one map to show, not two.

The storm in context

Where Sep 4, 2026 sits in Sonora's hail record.

This was Sonora's 16th recorded hail day, arriving 60 days after the Jul 6, 2026 storm. By severity it ranks 11th 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 Sep 4, 2026 convective day was bigger than Sonora: the same system put hail over 482 other tracked cities, 5 of them in Texas. Nearest: Robert Lee (104 miles north, up to 1.5"); Maryneal (128 miles north, up to 1"); Aspermont (190 miles north, up to 1").

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

No reports 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.

No ground reports were filed with the National Weather Service for this storm over Sonora. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Damage-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.

48 homes × $12,000 avg. claim

Potential roof exposure

$576K

Potential roof exposure — 48 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Claim window

September 2028

Claims from this storm can typically be filed until around September 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 $10 on top of the $150 plan.

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.
