Evidence / storm surfaces
How Saint Lawrence 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 Aug 28, 2026 — this storm produced no NEXRAD point detections over Saint Lawrence, so there is one map to show, not two.
The storm in context
Where Aug 28, 2026 sits in Saint Lawrence's hail record.
This was Saint Lawrence's 9th recorded hail day, arriving 34 days after the Jul 25, 2026 storm. By severity it ranks 7th of the 11 storms we have logged here. Radar put the day's largest stone over Saint Lawrence at 1" — radar-estimated size aloft.
The Aug 28, 2026 convective day was bigger than Saint Lawrence: the same system put hail over 185 other tracked cities, 28 of them in South Dakota. Nearest: Wessington (8 miles southeast, up to 1"); Hitchcock (20 miles northeast, up to 1.25"); Tulare (23 miles northeast, 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.
The National Weather Service logged no spotter reports for this storm over Saint Lawrence. 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" hail means for Saint Lawrence 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
$1.9M
Potential roof exposure — 155 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 155 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
Claims from this storm can typically be filed until around August 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 $33 on top of the $150 plan.
