How Harmony saw the hail — from two instruments

Sep 2, 2026 · Harmony, PA

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 hail size Surface resolved
Radar-estimated hail-size map of the storm over Harmony, PA on Sep 2, 2026 Estimated size field

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.

Max size 0.5"

Only the radar-estimated size surface resolved for Sep 2, 2026 — this storm produced no NEXRAD point detections over Harmony, so there is one map to show, not two.

The storm in context

Where Sep 2, 2026 sits in Harmony's hail record.

This was Harmony's 3rd recorded hail day, arriving 60 days after the Jul 4, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Harmony at 0.5" — radar-estimated size aloft.

The Sep 2, 2026 convective day was bigger than Harmony: the same system put hail over 356 other tracked cities, 100 of them in Pennsylvania. Nearest: Evans City (5 miles east, up to 0.5"); Cranberry Township (7 miles south, up to 0.5"); Freedom (9 miles southwest, up to 0.5").

These maps are stills. In the app this date is one of 3 Harmony 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

No reports filed with the NWS

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.

For this storm over Harmony, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

Below the severe threshold

What 0.5" hail means for Harmony roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 3, 2026.
