NEXRAD logged 5 hail signatures up to 1.5"; the estimated-size surface reached 0.75" aloft. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
This was Centerville's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Centerville at 1.5" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than Centerville: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Parker (7 miles north, up to 1.5"); Blue Mound (7 miles south, up to 1.5"); Mound City (13 miles southeast, up to 1.75").
These maps are stills. In the app this date is one of 5 Centerville 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
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.
“Shortly after 4:30 PM CDT on Sunday April 26th... an embedded circulation within a severe line of thunderstorms resulted in an EF 0 Tornado. This tornado started at 4:3 (EAX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Parker — beyond Centerville itself.
High damage potential
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.

Potential roof exposure — 34 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
