Evidence / storm surfaces
How Le Mars 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.
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 14, 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 14, 2026 sits in Le Mars's hail record.
This was Le Mars's 12th recorded hail day, arriving 13 days after the Sep 1, 2026 storm. By severity it ranks 12th of the 12 storms we have logged here. Radar put the day's largest stone over Le Mars at 0.5" — radar-estimated size aloft.
The Sep 14, 2026 convective day was bigger than Le Mars: the same system put hail over 110 other tracked cities, 24 of them in Iowa. Nearest: Merrill (7 miles south, up to 0.5"); Lyons (63 miles south, up to 0.75"); Craig (63 miles south, up to 0.5").
These maps are stills. In the app this date is one of 12 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.
Nobody on the ground filed a report over Le Mars 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 Le Mars 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
$1.8M
Potential roof exposure — 150 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 150 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 $32 on top of the $150 plan.
