How Sioux Falls saw the hail — from two instruments
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.
Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Only the radar-estimated size surface resolved for May 24, 2026 — this storm produced no NEXRAD point detections over Sioux Falls, so there is one map to show, not two.
Where May 24, 2026 sits in Sioux Falls's hail record
This was Sioux Falls's 3rd recorded hail day, arriving 7 days after the May 17, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over Sioux Falls at 1" — radar-estimated size aloft.
The May 24, 2026 convective day was bigger than Sioux Falls: the same system put hail over 200 other tracked cities, 25 of them in South Dakota. Nearest: Hartford (8 miles west, up to 1"); Harrisburg (10 miles southeast, up to 1.5"); Chancellor (10 miles southwest, up to 0.75").
These maps are stills from Sioux Falls's May 24, 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.
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.

What 1" hail means for Sioux Falls roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.

ground reports
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.
