The estimated-size surface reached 1" aloft; NEXRAD logged no point detections over Mound City that day. 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.

Evidence / storm surfaces
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 Apr 13, 2026 — this storm produced no NEXRAD point detections over Mound City, so there is one map to show, not two.
The storm in context
This was Mound City's 2nd recorded hail day, arriving 18 days after the Mar 26, 2026 storm. By severity it ranks 2nd of the 10 storms we have logged here. Radar put the day's largest stone over Mound City at 1" — radar-estimated size aloft.
The Apr 13, 2026 convective day was bigger than Mound City: the same system put hail over 467 other tracked cities, 32 of them in Kansas. Nearest: Pleasanton (9 miles northeast, up to 1"); Blue Mound (11 miles west, up to 1"); Hume (11 miles east, up to 1").
These maps are stills. In the app this date is one of 10 Mound City 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.
“*** 2 INJ *** Corrects previous tornado report from 2 SE Mound City. Around 8 PM on 13 April 2026... an EF-1 tornado associated with a supercell developed in far southw (EAX)”
— NOAA / SPC storm report
“A brief tornado was observed via videos taken by a drone and storm spotters north of the much longer track tornado. Location was estimated via video evidence and radar (EAX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 10 minutes, from to .
Damage-capable hail signal
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
Potential roof exposure
$17M
Potential roof exposure — 1,439 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,439 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 $302 on top of the $150 plan.
