How Oelrichs saw the hail — from two instruments
Aug 12, 2026 · Oelrichs, SD
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

The storm in context
Where Aug 12, 2026 sits in Oelrichs's hail record.
This was Oelrichs's 5th recorded hail day, arriving 36 days after the Jul 7, 2026 storm. By severity it ranks 3rd of the 8 storms we have logged here. Radar put the day's largest stone over Oelrichs at 2.5" — radar-estimated size aloft.
The Aug 12, 2026 convective day was bigger than Oelrichs: the same system put hail over 507 other tracked cities, 11 of them in South Dakota. Nearest: Hot Springs (18 miles northwest, up to 2.75"); Chadron (25 miles south, up to 2.25"); Edgemont (30 miles west, up to 2.75").
These maps are stills. In the app this date is one of 8 Oelrichs 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.

Severe hail signal
What 2.5" hail means for Oelrichs 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 7, 2026.
