Evidence / storm surfaces
How Kansas saw the hail — from two instruments
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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for May 4, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where May 4, 2026 sits in Kansas's hail record.
This was Kansas's 4th recorded hail day, arriving 1 day after the May 3, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Kansas at 1" — the largest NEXRAD radar signature.
The May 4, 2026 convective day was bigger than Kansas: the same system put hail over 428 other tracked cities, 239 of them in Illinois. Nearest: Paris (11 miles east, up to 1"); Newman (15 miles north, up to 0"); Charleston (19 miles southwest, up to 1").
These maps are stills. In the app this date is one of 6 Kansas 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 Kansas. 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.
Damage-capable hail signal
What 1" hail means for Kansas roofs.
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.
