Hail in Dupree · Jul 25, 2026
NEXRAD logged 24 hail signatures up to 2.25"; the estimated-size surface reached 1.5" aloft. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Dupree saw the hail — from two instruments
Jul 25, 2026 · Dupree, SD
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.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
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.

The storm in context
Where Jul 25, 2026 sits in Dupree's hail record.
This was Dupree's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Dupree at 2.25" — the largest NEXRAD radar signature.
The Jul 25, 2026 convective day was bigger than Dupree: the same system put hail over 303 other tracked cities, 102 of them in South Dakota. Nearest: Cherry Creek (17 miles south, up to 3"); Faith (25 miles west, up to 1.25"); Eagle Butte (30 miles east, up to 2.5").
These maps are stills. In the app this date is one of 3 Dupree 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.

Severe hail signal
What 2.25" hail means for Dupree 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.

112 homes × $12,000 avg. claim
Potential roof exposure

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 30, 2026.
