Evidence / storm surfaces
How San Antonio saw the hail — from two instruments
Jul 15, 2026 · San Antonio, 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
0.5"
Only the radar-estimated size surface resolved for Jul 15, 2026 — this storm produced no NEXRAD point detections over San Antonio, so there is one map to show, not two.
The storm in context
Where Jul 15, 2026 sits in San Antonio's hail record.
This was San Antonio's 7th recorded hail day, arriving 2 days after the Jul 13, 2026 storm. By severity it ranks 7th of the 10 storms we have logged here. Radar put the day's largest stone over San Antonio at 0.5" — radar-estimated size aloft.
The Jul 15, 2026 convective day was bigger than San Antonio: the same system put hail over 114 other tracked cities, 5 of them in Texas. Nearest: Yancey (58 miles west, up to 0.5"); Kerrville (72 miles northwest, up to 0.5"); Knippa (79 miles west, up to 0.5").
These maps are stills. In the app this date is one of 10 San Antonio 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.

Below the severe threshold
What 0.5" hail means for San Antonio roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

1,244 homes × $12,000 avg. claim
Potential roof exposure

Potential roof exposure — 1,244 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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 12, 2026.
