Evidence / storm surfaces
How Charleston 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 Apr 28, 2026 sits in Charleston's hail record.
This was Charleston's 4th recorded hail day, arriving 12 days after the Apr 16, 2026 storm. By severity it ranks 13th of the 14 storms we have logged here. Radar put the day's largest stone over Charleston at 0.5" — radar-estimated size aloft.
The Apr 28, 2026 convective day was bigger than Charleston: the same system put hail over 724 other tracked cities, 115 of them in Missouri. Nearest: Clinton (28 miles southeast, up to 0.75"); Hickory (33 miles east, up to 0.5"); Boaz (39 miles east, up to 0.75").
These maps are stills. In the app this date is one of 14 Charleston 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 Charleston. 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 Charleston 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$192K
Potential roof exposure — 16 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $3 on top of the $150 plan.
