Evidence / storm surfaces
How Greene 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 Jul 21, 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 Jul 21, 2026 sits in Greene's hail record.
This was Greene's 5th recorded hail day, arriving 3 days after the Jul 18, 2026 storm. By severity it ranks 5th of the 5 storms we have logged here. Radar put the day's largest stone over Greene at 0.5" — the largest NEXRAD radar signature.
The Jul 21, 2026 convective day was bigger than Greene: the same system put hail over 703 other tracked cities, 28 of them in New York. Nearest: Altamont (84 miles east, up to 0.75"); Livonia (105 miles west, up to 0.5"); Carthage (111 miles north, up to 1.25").

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.
No ground reports were filed with the National Weather Service for this storm over Greene. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0.5" hail means for Greene 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.
