Evidence / storm surfaces
How Wall saw the hail — from two instruments
Jul 27, 2026 · Wall, 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
1.5"
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Wall, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Wall's hail record.
This was Wall's 8th recorded hail day, arriving 20 days after the Jul 7, 2026 storm. By severity it ranks 7th of the 10 storms we have logged here. Radar put the day's largest stone over Wall at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Wall: the same system put hail over 803 other tracked cities, 11 of them in South Dakota. Nearest: Philip (22 miles northeast, up to 1.75"); Interior (30 miles southeast, up to 1.75"); Kadoka (40 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 10 Wall 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.

What people on the ground reported
1 report filed with the NWS
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.

High damage potential
What 1.5" hail means for Wall 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.
40 homes × $12,000 avg. claim
Potential roof exposure
$480K
Potential roof exposure — 40 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
July 2028
Claims from this storm can typically be filed until around July 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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 12, 2026.
