Evidence / storm surfaces
How Harrisburg saw the hail — from two instruments
May 24, 2026 · Harrisburg, SD
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
1.5"
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.
The storm in context
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 north, up to 1"); Lennox (10 miles southwest, up to 1.5"); Chancellor (15 miles west, up to 0.75").

Hail reports
1 reportHigh damage potential
What 1.5" hail means for Harrisburg 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 Aug 3, 2026.
