Hail in Camp Crook Apr 13, 2026

Both radar surfaces caught this storm: NEXRAD logged 17 hail signatures up to 2", and the radar-estimated size reached 1.5" aloft. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Two ways to read the storm

How Camp Crook 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.

Where Apr 13, 2026 sits in Camp Crook's hail record

This was Camp Crook's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Camp Crook at 2" — the largest NEXRAD radar signature.

The Apr 13, 2026 convective day was bigger than Camp Crook: the same system put hail over 467 other tracked cities, 8 of them in South Dakota. Nearest: Buffalo (15 miles south, up to 2"); Alzada (45 miles southwest, up to 1.75"); Broadus (71 miles west, up to 1.75").

These maps are stills from Camp Crook's Apr 13, 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.

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.

Nobody on the ground filed a report over Camp Crook for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Severe, roof-replacing hail

What 2" hail means for Camp Crook roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

Other storms in Camp Crook

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.
