Evidence / storm surfaces
How St John 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 Apr 26, 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 Apr 26, 2026 sits in St John's hail record.
This was St John's 3rd recorded hail day, arriving 1 day after the Apr 25, 2026 storm. By severity it ranks 9th of the 11 storms we have logged here. Radar put the day's largest stone over St John at 1" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than St John: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Larned (15 miles northwest, up to 0"); Hudson (21 miles northeast, up to 1"); Ellinwood (35 miles northeast, up to 1.25").
These maps are stills. In the app this date is one of 11 St John 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.
Nobody on the ground filed a report over St John for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for St John 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.
