Evidence / storm surfaces
How Mc Laughlin 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 Aug 30, 2026 sits in Mc Laughlin's hail record.
This was Mc Laughlin's 11th recorded hail day, arriving 1 day after the Aug 29, 2026 storm. By severity it ranks 8th of the 12 storms we have logged here. Radar put the day's largest stone over Mc Laughlin at 0.75" — radar-estimated size aloft.
The Aug 30, 2026 convective day was bigger than Mc Laughlin: the same system put hail over 117 other tracked cities, 11 of them in South Dakota. Nearest: Mc Intosh (18 miles west, up to 1"); Wakpala (22 miles southeast, up to 0.75"); Glenham (32 miles southeast, up to 0.5").

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 Mc Laughlin 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.
Near the severe threshold
What 0.75" hail means for Mc Laughlin roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
