Evidence / storm surfaces
How Charleston 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 Jun 12, 2026 — this storm produced no NEXRAD point detections over Charleston, so there is one map to show, not two.
The storm in context
Where Jun 12, 2026 sits in Charleston's hail record.
This was Charleston's 3rd recorded hail day, arriving 45 days after the Apr 28, 2026 storm. By severity it ranks 7th of the 8 storms we have logged here. Radar put the day's largest stone over Charleston at 0.5" — radar-estimated size aloft.
The Jun 12, 2026 convective day was bigger than Charleston: the same system put hail over 293 other tracked cities, 5 of them in Mississippi. Nearest: Sledge (24 miles northwest, up to 0.5"); Lexa (51 miles northwest, up to 0.5"); Marvell (55 miles west, up to 0.75").

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.
The National Weather Service logged no spotter reports for this storm over Charleston. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
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
$24K
Potential roof exposure — 2 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
June 2028
Claims from this storm can typically be filed until around June 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 $0 on top of the $150 plan.
