Evidence / storm surfaces
How Centralia 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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Only the NEXRAD radar-signature surface resolved for May 15, 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 15, 2026 sits in Centralia's hail record.
This was Centralia's 4th recorded hail day, arriving 11 days after the May 4, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Centralia at 1" — the largest NEXRAD radar signature.
The May 15, 2026 convective day was bigger than Centralia: the same system put hail over 444 other tracked cities, 7 of them in Missouri. Nearest: Hermann (54 miles southeast, up to 0"); New Haven (68 miles southeast, up to 0"); Concordia (78 miles west, up to 0").
These maps are stills. In the app this date is one of 6 Centralia 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.
The National Weather Service logged no spotter reports for this storm over Centralia. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1" hail means for Centralia 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.
