Evidence / storm surfaces
How Round O 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-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 Aug 27, 2026 — this storm produced no NEXRAD point detections over Round O, so there is one map to show, not two.
The storm in context
Where Aug 27, 2026 sits in Round O's hail record.
This was Round O's 7th recorded hail day, arriving 12 days after the Aug 15, 2026 storm. By severity it ranks 6th of the 7 storms we have logged here. Radar put the day's largest stone over Round O at 0.5" — radar-estimated size aloft.
The Aug 27, 2026 convective day was bigger than Round O: the same system put hail over 365 other tracked cities, 3 of them in South Carolina. Nearest: Islandton (32 miles northwest, up to 0.5"); Garnett (46 miles southwest, up to 0.5"); Springfield (49 miles southwest, up to 0.5").
These maps are stills. In the app this date is one of 7 Round O 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.
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 Round O. 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 Round O 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.
