Evidence / storm surfaces
How Powers Lake saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Sep 4, 2026 — this storm produced no NEXRAD point detections over Powers Lake, so there is one map to show, not two.
The storm in context
Where Sep 4, 2026 sits in Powers Lake's hail record.
This was Powers Lake's 10th recorded hail day, arriving 5 days after the Aug 30, 2026 storm. By severity it ranks 3rd of the 10 storms we have logged here. Radar put the day's largest stone over Powers Lake at 1" — radar-estimated size aloft.
The Sep 4, 2026 convective day was bigger than Powers Lake: the same system put hail over 482 other tracked cities, 29 of them in North Dakota. Nearest: Lignite (11 miles northeast, up to 1"); Flaxton (15 miles northeast, up to 1.5"); Bowbells (23 miles northeast, 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.
No ground reports were filed with the National Weather Service for this storm over Powers Lake. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Damage-capable hail signal
What 1" hail means for Powers Lake 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
$972K
Potential roof exposure — 81 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.
Names and phones for every home in the footprint: at most $17 on top of the $150 plan.
