Hail in Martin · Jun 28, 2026
NEXRAD logged 32 hail signatures up to 4"; the estimated-size surface reached 4" 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.

How Martin saw the hail — from two instruments
Jun 28, 2026 · Martin, 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 Martin's hail record.
This was Martin's 6th recorded hail day, arriving 1 day after the Jun 27, 2026 storm. By severity it ranks 1st of the 16 storms we have logged here. Radar put the day's largest stone over Martin at 4" — radar-estimated size aloft.
The Jun 28, 2026 convective day was bigger than Martin: the same system put hail over 348 other tracked cities, 42 of them in South Dakota. Nearest: Allen (7 miles north, up to 2.5"); Kyle (13 miles west, up to 2.5"); Batesland (17 miles southwest, up to 4").
These maps are stills. In the app this date is one of 16 Martin 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.

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 east at roughly 35 mph, based on the timing of ground reports.
Hail was reported over 67 minutes, from to .
Reports came from Vetal and Batesland — beyond Martin itself.
Severe hail signal
What 4" hail means for Martin 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 8, 2026.
