Evidence / storm surfaces
How San Antonio 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.
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.
The storm in context
Where Jul 13, 2026 sits in San Antonio's hail record.
This was San Antonio's 6th recorded hail day, arriving 48 days after the May 26, 2026 storm. By severity it ranks 8th of the 10 storms we have logged here. Radar put the day's largest stone over San Antonio at 0.75" — radar-estimated size aloft.
The Jul 13, 2026 convective day was bigger than San Antonio: the same system put hail over 92 other tracked cities, 15 of them in Texas. Nearest: New Braunfels (28 miles north, up to 1"); Seguin (32 miles northeast, up to 1"); Yancey (58 miles west, up to 0.5").

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 San Antonio. 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.
Near the severe threshold
What 0.75" hail means for San Antonio roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
