Hail in Deadwood Jun 22, 2026
Hit 42 days agoThe radar-estimated size surface caught this storm, reaching 2.25" aloft. NEXRAD logged no point detections over Deadwood this day. At 2.25" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Deadwood saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size
Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size
2.25"
Only the radar-estimated size surface resolved for Jun 22, 2026 — this storm produced no NEXRAD point detections over Deadwood, so there is one map to show, not two.
Where Jun 22, 2026 sits in Deadwood's hail record
This was Deadwood's 6th recorded hail day, arriving 16 days after the Jun 6, 2026 storm. By severity it ranks 1st of the 12 storms we have logged here. Radar put the day's largest stone over Deadwood at 2.25" — radar-estimated size aloft.
The Jun 22, 2026 convective day was bigger than Deadwood: the same system put hail over 258 other tracked cities, 14 of them in South Dakota. Nearest: Black Hawk (5 miles east, up to 1.25"); Rapid City (7 miles south, up to 1"); Custer (28 miles south, up to 1.25").
These maps are stills from Deadwood's Jun 22, 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 2.25" hail means for Deadwood 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.

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.
