Evidence / storm surfaces
How Tionesta 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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
The storm in context
Where Jul 21, 2026 sits in Tionesta's hail record.
This was Tionesta's 6th recorded hail day, arriving 11 days after the Jul 10, 2026 storm. By severity it ranks 1st of the 8 storms we have logged here. Radar put the day's largest stone over Tionesta at 1.5" — the largest NEXRAD radar signature.
The Jul 21, 2026 convective day was bigger than Tionesta: the same system put hail over 703 other tracked cities, 32 of them in Pennsylvania. Nearest: Pleasantville (9 miles northwest, up to 1.5"); Oil City (10 miles west, up to 1.5"); Titusville (23 miles northwest, up to 1.25").
These maps are stills. In the app this date is one of 8 Tionesta 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.
The National Weather Service logged no spotter reports for this storm over Tionesta. 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.
High damage potential
What 1.5" hail means for Tionesta 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.

Potential roof exposure
$1.3M
Potential roof exposure — 111 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs

- Illustrative work
- ~$15K
Close just 0.5% of the 111 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.
