Hail in Columbia · Jul 25, 2026
NEXRAD logged 1 hail signature up to 2"; the estimated-size surface reached 0" aloft. At 2" — 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 Columbia saw the hail — from two instruments
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
Where Jul 25, 2026 sits in Columbia's hail record.
This was Columbia's 4th recorded hail day, arriving 1 day after the Jul 24, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Columbia at 2" — the largest NEXRAD radar signature.
The Jul 25, 2026 convective day was bigger than Columbia: the same system put hail over 303 other tracked cities, 102 of them in South Dakota. Nearest: Groton (8 miles southeast, up to 0"); Bath (11 miles south, up to 0.5"); Aberdeen (21 miles southwest, up to 2.75").
These maps are stills. In the app this date is one of 5 Columbia 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
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 Columbia. 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 2" hail means for Columbia 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$180K
Potential roof exposure — 15 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.
Names and phones for every home in the footprint: at most $3 on top of the $150 plan.
