Evidence / storm surfaces
How Bonaparte 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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
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.
The storm in context
Where Aug 7, 2026 sits in Bonaparte's hail record.
This was Bonaparte's 6th recorded hail day, arriving 51 days after the Jun 17, 2026 storm. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Bonaparte at 1.75" — radar-estimated size aloft.
The Aug 7, 2026 convective day was bigger than Bonaparte: the same system put hail over 709 other tracked cities, 114 of them in Iowa. Nearest: Keosauqua (5 miles west, up to 2"); Stockport (7 miles north, up to 2.75"); Farmington (7 miles south, up to 2.25").

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 Bonaparte. 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.
High damage potential
What 1.75" hail means for Bonaparte roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$15M
Potential roof exposure — 1,214 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 6 jobs
- Illustrative work
- ~$90K
Close just 0.5% of the 1,214 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 $255 on top of the $150 plan.
