Evidence / storm surfaces

How Humboldt saw the hail — from two instruments

May 24, 2026 · Humboldt, 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.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Humboldt, SD on May 24, 2026 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.

Max size 1.5"

Only the radar-estimated size surface resolved for May 24, 2026 — this storm produced no NEXRAD point detections over Humboldt, so there is one map to show, not two.

The storm in context

Where May 24, 2026 sits in Humboldt's hail record.

This was Humboldt'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 Humboldt at 1.5" — radar-estimated size aloft.

The May 24, 2026 convective day was bigger than Humboldt: the same system put hail over 200 other tracked cities, 25 of them in South Dakota. Nearest: Parker (7 miles south, up to 1.25"); Canistota (8 miles west, up to 1.75"); Hartford (9 miles southeast, up to 1").

These maps are stills. In the app this date is one of 5 Humboldt 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 Humboldt. 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.

High damage potential

What 1.5" hail means for Humboldt roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 Sep 12, 2026.
