Evidence / storm surfaces
How Sedan saw the hail — from two instruments
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.
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 Sep 12, 2026 — this storm produced no NEXRAD point detections over Sedan, so there is one map to show, not two.
The storm in context
Where Sep 12, 2026 sits in Sedan's hail record.
This was Sedan's 15th recorded hail day, arriving 23 days after the Aug 20, 2026 storm. By severity it ranks 13th of the 15 storms we have logged here. Radar put the day's largest stone over Sedan at 0.5" — radar-estimated size aloft.
The Sep 12, 2026 convective day was bigger than Sedan: the same system put hail over 354 other tracked cities, 113 of them in Kansas. Nearest: Bartlesville (21 miles south, up to 0.5"); Shidler (26 miles southwest, up to 0.5"); Neodesha (39 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 15 Sedan 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.
No ground reports were filed with the National Weather Service for this storm over Sedan. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0.5" hail means for Sedan roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
