Evidence / storm surfaces
How Pine Ridge saw the hail — from two instruments
Aug 11, 2026 · Pine Ridge, 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 Aug 11, 2026 sits in Pine Ridge's hail record.
This was Pine Ridge's 10th recorded hail day, arriving 13 days after the Jul 29, 2026 storm. By severity it ranks 2nd of the 13 storms we have logged here. Radar put the day's largest stone over Pine Ridge at 2" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Pine Ridge: the same system put hail over 1,041 other tracked cities, 44 of them in South Dakota. Nearest: Rushville (12 miles southeast, up to 2"); Oglala (14 miles north, up to 2.25"); Gordon (23 miles southeast, up to 1.75").
These maps are stills. In the app this date is one of 13 Pine Ridge 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.

Storm forensics
How the storm moved
Timing and place names from NOAA ground reports
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked south at roughly 15 mph, based on the timing of ground reports.
Hail was reported over 32 minutes, from to .
Reports came from Clinton — beyond Pine Ridge itself.
Severe hail signal
What 2" hail means for Pine Ridge roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 7, 2026.
