Hail in Wall · Jul 3, 2026

NEXRAD logged 18 hail signatures up to 4"; the estimated-size surface reached 0.75" aloft. At 4" — softball or larger — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

How Wall saw the hail — from two instruments

Jul 3, 2026 · Wall, SD

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

The storm in context

Where Jul 3, 2026 sits in Wall's hail record.

This was Wall's 6th recorded hail day, arriving 1 day after the Jul 2, 2026 storm. By severity it ranks 2nd of the 10 storms we have logged here. Radar put the day's largest stone over Wall at 4" — the largest NEXRAD radar signature.

The Jul 3, 2026 convective day was bigger than Wall: the same system put hail over 1,885 other tracked cities, 32 of them in South Dakota. Nearest: Philip (22 miles northeast, up to 4"); New Underwood (28 miles west, up to 3.75"); Interior (30 miles southeast, up to 1.5").

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.

Ground reports

What people on the ground reported

No reports 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.

No ground reports were filed with the National Weather Service for this storm over Wall. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Severe hail signal

What 4" hail means for Wall 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 12, 2026.
