Evidence / storm surfaces
How Houston saw the hail — from two instruments
Aug 28, 2026 · Houston, TX
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.
Radar-estimated hail size Surface resolved
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.
Max size
1.25"
Only the radar-estimated size surface resolved for Aug 28, 2026 — this storm produced no NEXRAD point detections over Houston, so there is one map to show, not two.
The storm in context
Where Aug 28, 2026 sits in Houston's hail record.
This was Houston's 19th recorded hail day, arriving 36 days after the Jul 23, 2026 storm. By severity it ranks 6th of the 19 storms we have logged here. Radar put the day's largest stone over Houston at 1.25" — radar-estimated size aloft.
The Aug 28, 2026 convective day was bigger than Houston: the same system put hail over 185 other tracked cities, 72 of them in Texas. Nearest: Tomball (9 miles west, up to 1"); Humble (9 miles east, up to 1"); Hockley (24 miles west, up to 0.75").
These maps are stills. In the app this date is one of 19 Houston 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.

Damage-capable hail signal
What 1.25" hail means for Houston 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.
74,380 homes × $12,000 avg. claim
Potential roof exposure
$893M
Potential roof exposure — 74,380 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 372 jobs
- Illustrative work
- ~$5.6M
Close just 0.5% of the 74,380 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 $15,620 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 Aug 29, 2026.
