Evidence / storm surfaces
How Canton saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
The storm in context
Where Jul 4, 2026 sits in Canton's hail record.
This was Canton's 6th recorded hail day, arriving 4 days after the Jun 30, 2026 storm. By severity it ranks 3rd of the 8 storms we have logged here. Radar put the day's largest stone over Canton at 1.75" — the largest NEXRAD radar signature.
The Jul 4, 2026 convective day was bigger than Canton: the same system put hail over 2,035 other tracked cities, 30 of them in South Dakota. Nearest: Inwood (11 miles east, up to 1"); Harrisburg (12 miles northwest, up to 1.75"); Rock Valley (15 miles east, up to 1").

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.
No ground reports were filed with the National Weather Service for this storm over Canton. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
High damage potential
What 1.75" hail means for Canton 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.
