The 3rd most severe storm Columbia has seen in the last 12 months
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
How Columbia saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Jun 28, 2026 sits in Columbia's hail record.
This was Columbia's 2nd recorded hail day, arriving 14 days after the Jun 14, 2026 storm. By severity it ranks 3rd of the 5 storms we have logged here. Radar put the day's largest stone over Columbia at 1" — the largest NEXRAD radar signature.
The Jun 28, 2026 convective day was bigger than Columbia: the same system put hail over 348 other tracked cities, 24 of them in North Carolina. Nearest: Engelhard (21 miles south, up to 1"); Plymouth (29 miles west, up to 1.25"); Swanquarter (35 miles south, up to 1").
These maps are stills. In the app this date is one of 5 Columbia 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.
Nobody on the ground filed a report over Columbia 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.
Damage-capable hail signal
What 1" hail means for Columbia 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.
