How Beresford saw the hail — from two instruments

May 31, 2026 · Beresford, 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 — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

The storm in context

Where May 31, 2026 sits in Beresford's hail record.

This was Beresford's 3rd recorded hail day, arriving 7 days after the May 24, 2026 storm. By severity it ranks 1st of the 13 storms we have logged here. Radar put the day's largest stone over Beresford at 2.5" — the largest NEXRAD radar signature.

The May 31, 2026 convective day was bigger than Beresford: the same system put hail over 637 other tracked cities, 61 of them in South Dakota. Nearest: Centerville (6 miles northwest, up to 2.5"); Davis (13 miles northwest, up to 2.5"); Wakonda (13 miles west, up to 1.75").

These maps are stills. In the app this date is one of 13 Beresford 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.

Storm forensics

How the storm moved

Timing and place names from NOAA ground reports

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.

The storm tracked east at roughly 10 mph, based on the timing of ground reports.

Hail was reported over 97 minutes, from to .

Reports came from Vermillion, Alcester, and Centerville — beyond Beresford itself.

Severe hail signal

What 2.5" hail means for Beresford 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.

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.
