Hail in Manderson · Jun 28, 2026
NEXRAD logged 8 hail signatures up to 4"; the estimated-size surface reached 2.25" aloft. At 4" — softball or larger — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Manderson saw the hail — from two instruments
Jun 28, 2026 · Manderson, 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 Jun 28, 2026 sits in Manderson's hail record.
This was Manderson's 5th recorded hail day, arriving 1 day after the Jun 27, 2026 storm. By severity it ranks 1st of the 10 storms we have logged here. Radar put the day's largest stone over Manderson at 4" — the largest NEXRAD radar signature.
The Jun 28, 2026 convective day was bigger than Manderson: the same system put hail over 348 other tracked cities, 42 of them in South Dakota. Nearest: Oglala (8 miles northwest, up to 2.25"); Wounded Knee (9 miles southeast, up to 4"); Porcupine (11 miles east, up to 4").
These maps are stills. In the app this date is one of 10 Manderson 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.

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.
Reports came from Wounded Knee — beyond Manderson itself.
Severe hail signal
What 4" hail means for Manderson 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.
