Evidence / storm surfaces
How Pierre saw the hail — from two instruments
Jun 9, 2026 · Pierre, SD
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
1.5"
Only the radar-estimated size surface resolved for Jun 9, 2026 — this storm produced no NEXRAD point detections over Pierre, so there is one map to show, not two.
The storm in context
Where Jun 9, 2026 sits in Pierre's hail record.
This was Pierre's 4th recorded hail day, arriving 5 days after the Jun 4, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over Pierre at 1.5" — radar-estimated size aloft.
The Jun 9, 2026 convective day was bigger than Pierre: the same system put hail over 646 other tracked cities, 67 of them in South Dakota. Nearest: Blunt (22 miles southeast, up to 1"); Fort Pierre (23 miles southwest, up to 1.5"); Harrold (31 miles east, up to 1").

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 northeast at roughly 30 mph, based on the timing of ground reports.
Hail was reported over 43 minutes, from to .
Reports came from Fort Pierre, Blunt, and Canning — beyond Pierre itself.
High damage potential
What 1.5" hail means for Pierre 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 7, 2026.
