Evidence / storm surfaces
How Summerton 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 Jul 20, 2026 — this storm produced no NEXRAD point detections over Summerton, so there is one map to show, not two.
The storm in context

This was Summerton's 3rd recorded hail day, arriving 9 days after the Jul 11, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Summerton at 1" — radar-estimated size aloft.
The Jul 20, 2026 convective day was bigger than Summerton: the same system put hail over 553 other tracked cities, 4 of them in South Carolina. Nearest: Eutawville (15 miles southeast, up to 1"); Saint George (36 miles south, up to 0.5"); Cordesville (44 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 6 Summerton 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 Summerton. 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.
Damage-capable hail signal
What 1" hail means for Summerton roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
