Evidence / storm surfaces
How Sturgis 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 signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
Where Jun 26, 2026 sits in Sturgis's hail record.
This was Sturgis's 4th recorded hail day, arriving 22 days after the Jun 4, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Sturgis at 1.75" — the largest NEXRAD radar signature.
The Jun 26, 2026 convective day was bigger than Sturgis: the same system put hail over 440 other tracked cities, 33 of them in South Dakota. Nearest: Vale (7 miles north, up to 1"); Whitewood (13 miles northwest, up to 1"); Black Hawk (14 miles south, up to 1").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Ellsworth Afb — beyond Sturgis itself.
High damage potential
What 1.75" hail means for Sturgis roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$14M
Potential roof exposure — 1,129 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 6 jobs
- Illustrative work
- ~$90K
Close just 0.5% of the 1,129 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
June 2028
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.
Names and phones for every home in the footprint: at most $237 on top of the $150 plan.
