Evidence / storm surfaces
How Canistota saw the hail — from two instruments
May 24, 2026 · Canistota, 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.
Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Max size
1.75"
Only the radar-estimated size surface resolved for May 24, 2026 — this storm produced no NEXRAD point detections over Canistota, so there is one map to show, not two.
The storm in context
Where May 24, 2026 sits in Canistota's hail record.
This was Canistota's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Canistota at 1.75" — radar-estimated size aloft.
The May 24, 2026 convective day was bigger than Canistota: the same system put hail over 200 other tracked cities, 25 of them in South Dakota. Nearest: Humboldt (8 miles east, up to 1.5"); Bridgewater (10 miles southwest, up to 1.25"); Parker (10 miles southeast, up to 1.25").
These maps are stills. In the app this date is one of 8 Canistota 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.

High damage potential
What 1.75" hail means for Canistota 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.
