The estimated-size surface reached 2" aloft; NEXRAD logged no point detections over Osawatomie that day. At 2" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

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.
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.
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Osawatomie, so there is one map to show, not two.
The storm in context
This was Osawatomie's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Osawatomie at 2" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Osawatomie: the same system put hail over 425 other tracked cities, 34 of them in Kansas. Nearest: Greeley (5 miles west, up to 1.75"); Paola (16 miles northeast, up to 1.75"); Pleasanton (21 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 6 Osawatomie 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.
“Several social media photos and videos of hail up to tennis ball size in Osawatomie. Multiple homes and vehicles were damaged... with many windows and windshields crack (EAX)”

Severe hail signal
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
Potential roof exposure
$40M
Potential roof exposure — 3,301 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 3,301 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
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.
Names and phones for every home in the footprint: at most $693 on top of the $150 plan.
