Evidence / storm surfaces
How Parker saw the hail — from two instruments
Jul 2, 2026 · Parker, SD
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
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.

The storm in context
Where Jul 2, 2026 sits in Parker's hail record.
This was Parker's 6th recorded hail day, arriving 2 days after the Jun 30, 2026 storm. By severity it ranks 3rd of the 10 storms we have logged here. Radar put the day's largest stone over Parker at 1.75" — the largest NEXRAD radar signature.
The Jul 2, 2026 convective day was bigger than Parker: the same system put hail over 1,147 other tracked cities, 153 of them in South Dakota. Nearest: Monroe (5 miles west, up to 1.75"); Hartford (5 miles east, up to 1"); Humboldt (7 miles north, up to 0.5").

High damage potential
What 1.75" hail means for Parker 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 12, 2026.
