Evidence / storm surfaces
How Houston saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for Apr 4, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Apr 4, 2026 sits in Houston's hail record.
This was Houston's 3rd recorded hail day, arriving 28 days after the Mar 7, 2026 storm. By severity it ranks 12th of the 19 storms we have logged here. Radar put the day's largest stone over Houston at 1" — the largest NEXRAD radar signature.
The Apr 4, 2026 convective day was bigger than Houston: the same system put hail over 26 other tracked cities, 5 of them in Texas. Nearest: Dayton (28 miles east, up to 1.25"); Robstown (206 miles southwest, up to 1.25"); Bishop (211 miles southwest, up to 1.25").
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.
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.
The National Weather Service logged no spotter reports for this storm over Houston. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1" 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.
Potential roof exposure
$48M
Potential roof exposure — 3,987 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 20 jobs
- Illustrative work
- ~$300K
Close just 0.5% of the 3,987 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
April 2028
Claims from this storm can typically be filed until around April 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 $837 on top of the $150 plan.
