Hail in Deadwood · Jun 22, 2026
The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Deadwood that day. At 2.25" — tennis ball — 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 Deadwood saw the hail — from two instruments
Jun 22, 2026 · Deadwood, SD
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 Surface resolved
Estimated size field 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.
The storm in context
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 17 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: Rapid City (5 miles east, up to 1"); Black Hawk (12 miles northeast, up to 1.25"); Custer (26 miles south, up to 1.25").
These maps are stills. In the app this date is one of 17 Deadwood 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 southeast at roughly 20 mph, based on the timing of ground reports.
Hail was reported over 38 minutes, from to .
Reports came from Brownsville, Galena, and Nemo — beyond Deadwood itself.
Severe hail signal
What 2.25" hail means for Deadwood 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 Aug 24, 2026.
