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.
NEXRAD radar signatures
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.

Where Jul 4, 2026 sits in St John's hail record
This was St John's 9th recorded hail day, arriving 9 days after the Jun 25, 2026 storm. By severity it ranks 4th of the 10 storms we have logged here. Radar put the day's largest stone over St John at 1.25" — the largest NEXRAD radar signature.
The Jul 4, 2026 convective day was bigger than St John: the same system put hail over 2,035 other tracked cities, 132 of them in Kansas. Nearest: Stafford (9 miles northeast, up to 1.25"); Pratt (28 miles south, up to 0.75"); Great Bend (29 miles north, up to 1.5").
These maps are stills from St John's Jul 4, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

Reports came from Macksville — beyond St John itself.
What 1.25" hail means for St John roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer
$1.2M
Potential roof exposure — 97 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
