Hail in Graham · Apr 15, 2026
The estimated-size surface reached 3" aloft; NEXRAD logged no point detections over Graham that day. At 3" — baseball — 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 Graham 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.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Graham, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Graham's hail record.
This was Graham's 5th recorded hail day, arriving 12 days after the Apr 3, 2026 storm. By severity it ranks 1st of the 11 storms we have logged here. Radar put the day's largest stone over Graham at 3" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Graham: the same system put hail over 425 other tracked cities, 47 of them in Texas. Nearest: Breckenridge (10 miles south, up to 3"); Woodson (12 miles west, up to 3"); Caddo (18 miles southeast, up to 1.5").
These maps are stills. In the app this date is one of 11 Graham 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked southeast at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 67 minutes, from to .
Severe hail signal
What 3" hail means for Graham 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
$123M
Potential roof exposure — 10,216 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 51 jobs
- Illustrative work
- ~$765K
Close just 0.5% of the 10,216 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 $2,145 on top of the $150 plan.
