Evidence / storm surfaces
How Philadelphia saw the hail — from two instruments
Aug 20, 2026 · Philadelphia, MS
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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
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 20, 2026 sits in Philadelphia's hail record.
This was Philadelphia's 13th recorded hail day, arriving 1 day after the Aug 19, 2026 storm. By severity it ranks 7th of the 15 storms we have logged here. Radar put the day's largest stone over Philadelphia at 1" — radar-estimated size aloft.
The Aug 20, 2026 convective day was bigger than Philadelphia: the same system put hail over 640 other tracked cities, 92 of them in Mississippi. Nearest: Union (9 miles southeast, up to 1.5"); Walnut Grove (9 miles southwest, up to 0.75"); Lena (14 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 15 Philadelphia 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.

Damage-capable hail signal
What 1" hail means for Philadelphia 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.
1,564 homes × $12,000 avg. claim
Potential roof exposure
$19M
Potential roof exposure — 1,564 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

- ~$120K
Close just 0.5% of the 1,564 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.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 8, 2026.
