Evidence / storm surfaces
How Jamestown 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 Aug 11, 2026 sits in Jamestown's hail record.
This was Jamestown's 2nd recorded hail day, arriving 119 days after the Apr 14, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Jamestown at 1" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Jamestown: the same system put hail over 1,041 other tracked cities, 170 of them in Indiana. Nearest: Lebanon (6 miles northeast, up to 0.75"); Lizton (7 miles south, up to 0.75"); Pittsboro (9 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 3 Jamestown 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 Jamestown 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 Jamestown 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
$13M
Potential roof exposure — 1,043 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 5 jobs
- Illustrative work
- ~$75K
Close just 0.5% of the 1,043 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 $219 on top of the $150 plan.
