Evidence / storm surfaces
How South Park 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.
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 Sep 3, 2026 — this storm produced no NEXRAD point detections over South Park, so there is one map to show, not two.
The storm in context
Where Sep 3, 2026 sits in South Park's hail record.
This was South Park's 4th recorded hail day, arriving 24 days after the Aug 10, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over South Park at 1.5" — radar-estimated size aloft.
The Sep 3, 2026 convective day was bigger than South Park: the same system put hail over 494 other tracked cities, 54 of them in Pennsylvania. Nearest: Canonsburg (8 miles west, up to 1.5"); Homestead (9 miles northeast, up to 1.5"); Carnegie (9 miles northwest, up to 1.5").

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 South Park 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.
High damage potential
What 1.5" hail means for South Park roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$504M
Potential roof exposure — 41,986 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 210 jobs
- Illustrative work
- ~$3.2M
Close just 0.5% of the 41,986 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
September 2028
Claims from this storm can typically be filed until around September 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 $8,817 on top of the $150 plan.
