Evidence / storm surfaces
How Johnson City 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 May 19, 2026 — this storm produced no NEXRAD point detections over Johnson City, so there is one map to show, not two.
The storm in context
Where May 19, 2026 sits in Johnson City's hail record.
This was Johnson City's 4th recorded hail day, arriving 13 days after the May 6, 2026 storm. By severity it ranks 7th of the 7 storms we have logged here. Radar put the day's largest stone over Johnson City at 0.5" — radar-estimated size aloft.
The May 19, 2026 convective day was bigger than Johnson City: the same system put hail over 263 other tracked cities, 151 of them in Texas. Nearest: Round Mountain (14 miles north, up to 0.75"); Marble Falls (23 miles northeast, up to 1"); Blanco (23 miles southwest, up to 1").

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.
For this storm over Johnson City, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Johnson City 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.
