The 11th most severe storm Lead has seen in the last 12 months

Evidence / storm surfaces
How Lead 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 10, 2026 sits in Lead's hail record.
This was Lead's 10th recorded hail day, arriving 2 days after the Jul 8, 2026 storm. By severity it ranks 11th of the 14 storms we have logged here. Radar put the day's largest stone over Lead at 1" — the largest NEXRAD radar signature.
The Jul 10, 2026 convective day was bigger than Lead: the same system put hail over 682 other tracked cities, 7 of them in South Dakota. Nearest: Hill City (14 miles south, up to 0.75"); Burns (210 miles south, up to 0"); Cheyenne (218 miles south, up to 1").
These maps are stills. In the app this date is one of 14 Lead 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.
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 Lead 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.
Damage-capable hail signal
What 1" hail means for Lead 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.
