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 Aug 22, 2026 — this storm produced no NEXRAD point detections over Sonora, so there is one map to show, not two.
The storm in context
Where Aug 22, 2026 sits in Sonora's hail record.
This was Sonora's 2nd recorded hail day, arriving 11 days after the Aug 11, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Sonora at 1" — radar-estimated size aloft.
The Aug 22, 2026 convective day was bigger than Sonora: the same system put hail over 501 other tracked cities, 42 of them in Kentucky. Nearest: Bonnieville (9 miles southeast, up to 1.25"); Eastview (9 miles northwest, up to 1"); Munfordville (12 miles southeast, up to 1.25").
These maps are stills. In the app this date is one of 2 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.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from White Mills — beyond Sonora itself.
Damage-capable hail signal
What 1" 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.
Potential roof exposure
$19M
Potential roof exposure — 1,595 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 8 jobs
- Illustrative work
- ~$120K
Close just 0.5% of the 1,595 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.
Names and phones for every home in the footprint: at most $335 on top of the $150 plan.
