Evidence / storm surfaces
How Charleston saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Aug 19, 2026 — this storm produced no NEXRAD point detections over Charleston, so there is one map to show, not two.
The storm in context
Where Aug 19, 2026 sits in Charleston's hail record.
This was Charleston's 14th recorded hail day, arriving 41 days after the Jul 9, 2026 storm. By severity it ranks 8th of the 14 storms we have logged here. Radar put the day's largest stone over Charleston at 1" — radar-estimated size aloft.
The Aug 19, 2026 convective day was bigger than Charleston: the same system put hail over 496 other tracked cities, 57 of them in Missouri. Nearest: Bertrand (12 miles west, up to 0.75"); Wickliffe (14 miles east, up to 0.75"); East Prairie (14 miles south, 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.
Damage-capable hail signal
What 1" hail means for Charleston 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$45M
Potential roof exposure — 3,777 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 19 jobs
- Illustrative work
- ~$285K
Close just 0.5% of the 3,777 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
August 2028
Claims from this storm can typically be filed until around August 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 $793 on top of the $150 plan.
