Evidence / storm surfaces
How Lake Andes saw the hail — from two instruments
Sep 7, 2026 · Lake Andes, SD
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.
Radar-estimated hail size Surface resolved
Map image is still rendering for this surface.
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 7, 2026 — this storm produced no NEXRAD point detections over Lake Andes, so there is one map to show, not two.
The storm in context
Where Sep 7, 2026 sits in Lake Andes's hail record.
This was Lake Andes's 6th recorded hail day, arriving 6 days after the Sep 1, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Lake Andes at 0.5" — radar-estimated size aloft.
The Sep 7, 2026 convective day was bigger than Lake Andes: the same system put hail over 163 other tracked cities, 19 of them in South Dakota. Nearest: Geddes (8 miles west, up to 0.75"); Armour (9 miles northeast, up to 0.75"); Bristow (14 miles south, up to 0.75").
These maps are stills. In the app this date is one of 6 Lake Andes 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
1 report filed with the NWS
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.
Hail reports
1 reportBelow the severe threshold
What 0.5" hail means for Lake Andes 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.
205 homes × $12,000 avg. claim
Potential roof exposure
$2.5M
Potential roof exposure — 205 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 205 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
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.
Names and phones for every home in the footprint: at most $43 on top of the $150 plan.

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 8, 2026.
