How Philadelphia saw the hail — from two instruments
Apr 28, 2026 · Philadelphia, MS
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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
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 Apr 28, 2026 sits in Philadelphia's hail record.
This was Philadelphia's 3rd recorded hail day, arriving 4 days after the Apr 24, 2026 storm. By severity it ranks 2nd of the 16 storms we have logged here. Radar put the day's largest stone over Philadelphia at 1.25" — radar-estimated size aloft.
The Apr 28, 2026 convective day was bigger than Philadelphia: the same system put hail over 724 other tracked cities, 98 of them in Mississippi. Nearest: Collinsville (7 miles south, up to 1.25"); Preston (9 miles northwest, up to 1.25"); Bailey (15 miles southeast, up to 1").
These maps are stills. In the app this date is one of 16 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 1.25" 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.
455 homes × $12,000 avg. claim
Potential roof exposure
$5.5M
Potential roof exposure — 455 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 455 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
April 2028
Claims from this storm can typically be filed until around April 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 $96 on top of the $150 plan.

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 13, 2026.
