Evidence / storm surfaces
How Iowa 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 May 23, 2026 — this storm produced no NEXRAD point detections over Iowa, so there is one map to show, not two.
The storm in context
Where May 23, 2026 sits in Iowa's hail record.
This was Iowa's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Iowa at 0.75" — radar-estimated size aloft.
The May 23, 2026 convective day was bigger than Iowa: the same system put hail over 222 other tracked cities, 6 of them in Louisiana. Nearest: Lake Charles (16 miles southwest, up to 1"); Deridder (35 miles north, up to 0.5"); Abbeville (58 miles east, up to 0.5").
These maps are stills. In the app this date is one of 4 Iowa 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.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Lake Charles — beyond Iowa itself.
Near the severe threshold
What 0.75" hail means for Iowa roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$93M
Potential roof exposure — 7,776 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 39 jobs
- Illustrative work
- ~$585K
Close just 0.5% of the 7,776 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
May 2028
Claims from this storm can typically be filed until around May 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 $1,633 on top of the $150 plan.
