NEXRAD logged 54 hail signatures up to 2.5"; the estimated-size surface reached 2" aloft. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
This was White River's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 13 storms we have logged here. Radar put the day's largest stone over White River at 2.5" — the largest NEXRAD radar signature.
The Jun 2, 2026 convective day was bigger than White River: the same system put hail over 635 other tracked cities, 48 of them in South Dakota. Nearest: Wood (17 miles southeast, up to 2.5"); Belvidere (18 miles northwest, up to 2"); Mission (24 miles southeast, up to 2.5").
These maps are stills. In the app this date is one of 13 White River 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
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.
“Estimated ping pong ball size hail... zero visibility... very strong winds at least over 60 MPH rocking truck back and forth. Street flooding now occurring across White (UNR)”

Severe hail signal
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.

Roofing exposure
Potential roof exposure
$6.5M
Potential roof exposure — 543 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 543 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
June 2028
Claims from this storm can typically be filed until around June 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 $114 on top of the $150 plan.
