Evidence / storm surfaces
How Le Mars 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.
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.
Only the radar-estimated size surface resolved for Sep 1, 2026 — this storm produced no NEXRAD point detections over Le Mars, so there is one map to show, not two.
The storm in context
Where Sep 1, 2026 sits in Le Mars's hail record.
This was Le Mars's 11th recorded hail day, arriving 4 days after the Aug 28, 2026 storm. By severity it ranks 4th of the 11 storms we have logged here. Radar put the day's largest stone over Le Mars at 1.25" — radar-estimated size aloft.
The Sep 1, 2026 convective day was bigger than Le Mars: the same system put hail over 362 other tracked cities, 47 of them in Iowa. Nearest: Merrill (9 miles southwest, up to 0.75"); Ireton (13 miles northwest, up to 1.25"); Maurice (14 miles north, up to 1.5").
These maps are stills. In the app this date is one of 11 Le Mars 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.
No ground reports were filed with the National Weather Service for this storm over Le Mars. 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 1.25" hail means for Le Mars 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
$87M
Potential roof exposure — 7,224 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 36 jobs
- Illustrative work
- ~$540K
Close just 0.5% of the 7,224 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 $1,517 on top of the $150 plan.
