Evidence / storm surfaces
How Madison 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 Aug 6, 2026 sits in Madison's hail record.
This was Madison's 4th recorded hail day, arriving 12 days after the Jul 25, 2026 storm. By severity it ranks 3rd of the 6 storms we have logged here. Radar put the day's largest stone over Madison at 1.25" — radar-estimated size aloft.
The Aug 6, 2026 convective day was bigger than Madison: the same system put hail over 461 other tracked cities, 27 of them in South Dakota. Nearest: Colton (7 miles south, up to 0.75"); Salem (10 miles southwest, up to 2.25"); Ramona (14 miles north, up to 1.5").

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.
The National Weather Service logged no spotter reports for this storm over Madison. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1.25" hail means for Madison roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$25M
Potential roof exposure — 2,099 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 10 jobs
- Illustrative work
- ~$150K
Close just 0.5% of the 2,099 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
August 2028
