Evidence / storm surfaces
How Lacona 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 Jul 20, 2026 — this storm produced no NEXRAD point detections over Lacona, so there is one map to show, not two.
The storm in context
Where Jul 20, 2026 sits in Lacona's hail record.
This was Lacona's 3rd recorded hail day, arriving 39 days after the Jun 11, 2026 storm. By severity it ranks 3rd of the 3 storms we have logged here. Radar put the day's largest stone over Lacona at 1.5" — radar-estimated size aloft.
The Jul 20, 2026 convective day was bigger than Lacona: the same system put hail over 553 other tracked cities, 178 of them in Iowa. Nearest: Melcher Dallas (8 miles east, up to 1.75"); Chariton (10 miles southeast, up to 1.5"); Lucas (10 miles southwest, up to 0.5").

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.
Nobody on the ground filed a report over Lacona 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.
High damage potential
What 1.5" hail means for Lacona 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
$30M
Potential roof exposure — 2,481 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 12 jobs
- Illustrative work
- ~$180K
Close just 0.5% of the 2,481 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
July 2028
Claims from this storm can typically be filed until around July 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 $521 on top of the $150 plan.
