How Wall 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
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.
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 6th of the 9 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 (15 miles east, up to 1.75"); Kadoka (34 miles southeast, up to 0.75"); Interior (37 miles south, up to 1.75").
These maps are stills from Wall's Jul 27, 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 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
Reports came from Creighton — beyond Wall itself.
What 1.5" hail means for Wall roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
What this storm is worth to a roofer
$480K
Potential roof exposure — 40 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. 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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
