Evidence / storm surfaces
How Armour saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Aug 17, 2026 — this storm produced no NEXRAD point detections over Armour, so there is one map to show, not two.
The storm in context
Where Aug 17, 2026 sits in Armour's hail record.
This was Armour's 6th recorded hail day, arriving 14 days after the Aug 3, 2026 storm. By severity it ranks 7th of the 8 storms we have logged here. Radar put the day's largest stone over Armour at 0.75" — radar-estimated size aloft.
The Aug 17, 2026 convective day was bigger than Armour: the same system put hail over 428 other tracked cities, 29 of them in South Dakota. Nearest: Lake Andes (9 miles southwest, up to 0.75"); Platte (21 miles west, up to 1"); White Lake (23 miles northwest, up to 0.75").

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.
Nobody on the ground filed a report over Armour for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Near the severe threshold
What 0.75" hail means for Armour roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.2M
Potential roof exposure — 104 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 104 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
August 2028
Claims from this storm can typically be filed until around August 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 $22 on top of the $150 plan.
