Evidence / storm surfaces
How Rock Hill 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 Jun 28, 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

This was Rock Hill's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Rock Hill at 0.75" — the largest NEXRAD radar signature.
The Jun 28, 2026 convective day was bigger than Rock Hill: the same system put hail over 348 other tracked cities, 2 of them in South Carolina. Nearest: Waxhaw (22 miles northeast, up to 0.75"); Chesnee (50 miles northwest, up to 0.75"); Little Rock (99 miles east, 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.
Nobody on the ground filed a report over Rock Hill for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Near the severe threshold
What 0.75" hail means for Rock Hill 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.
