How Harrisburg saw the hail — from two instruments
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
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.

Only the radar-estimated size surface resolved for May 24, 2026 — this storm produced no NEXRAD point detections over Harrisburg, so there is one map to show, not two.
Where May 24, 2026 sits in Harrisburg's hail record
This was Harrisburg's 2nd recorded hail day, arriving 7 days after the May 17, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Harrisburg at 1.5" — radar-estimated size aloft.
The May 24, 2026 convective day was bigger than Harrisburg: the same system put hail over 200 other tracked cities, 25 of them in South Dakota. Nearest: Sioux Falls (10 miles northwest, up to 1"); Lennox (10 miles southwest, up to 1.5"); Larchwood (12 miles northeast, up to 1").
These maps are stills from Harrisburg's May 24, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.
Hail reports
1 reportWhat 1.5" hail means for Harrisburg roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
What this storm is worth to a roofer

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
