Evidence / storm surfaces
How Nemo 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.
Estimated size field 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 Sep 6, 2026 — this storm produced no NEXRAD point detections over Nemo, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Nemo's hail record.
This was Nemo's 8th recorded hail day, arriving 21 days after the Aug 16, 2026 storm. By severity it ranks 8th of the 8 storms we have logged here. Radar put the day's largest stone over Nemo at 0.5" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Nemo: the same system put hail over 608 other tracked cities, 33 of them in South Dakota. Nearest: Rapid City (9 miles southeast, up to 0.5"); Black Hawk (10 miles east, up to 0.5"); Osage (46 miles west, up to 2").
These maps are stills. In the app this date is one of 8 Nemo 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 Nemo 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.
Below the severe threshold
What 0.5" hail means for Nemo roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$132K
Potential roof exposure — 11 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
