Evidence / storm surfaces
How Greenville saw the hail — from two instruments
Apr 15, 2026 · Greenville, PA
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size
1.75"
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Greenville, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Greenville's hail record.
This was Greenville's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Greenville at 1.75" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Greenville: the same system put hail over 425 other tracked cities, 25 of them in Pennsylvania. Nearest: Clarks Mills (5 miles east, up to 1.75"); Mercer (9 miles southeast, up to 1.75"); Stoneboro (12 miles southeast, up to 2").
These maps are stills. In the app this date is one of 4 Greenville 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.

High damage potential
What 1.75" hail means for Greenville 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.

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 4, 2026.
