Hail in Sisseton Jun 29, 2026
Hit 35 days agoBoth radar surfaces caught this storm: NEXRAD logged 5 hail signatures up to 2", and the radar-estimated size reached 1.25" aloft. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Sisseton saw the hail — from two instruments
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.

Where Jun 29, 2026 sits in Sisseton's hail record
This was Sisseton's 3rd recorded hail day, arriving 14 days after the Jun 15, 2026 storm. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Sisseton at 2" — the largest NEXRAD radar signature.
The Jun 29, 2026 convective day was bigger than Sisseton: the same system put hail over 702 other tracked cities, 51 of them in South Dakota. Nearest: Claire City (7 miles north, up to 1.75"); Eden (12 miles southwest, up to 1.75"); Veblen (17 miles northwest, up to 2.25").
These maps are stills from Sisseton's Jun 29, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
What people on the ground reported

What 2" hail means for Sisseton roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
What this storm is worth to a roofer
$528K
Potential roof exposure — 44 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
