Evidence / storm surfaces
How Heavener saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Sep 21, 2026 — this storm produced no NEXRAD point detections over Heavener, so there is one map to show, not two.
The storm in context
Where Sep 21, 2026 sits in Heavener's hail record.
This was Heavener's 11th recorded hail day, arriving 26 days after the Aug 26, 2026 storm. By severity it ranks 11th of the 11 storms we have logged here. Radar put the day's largest stone over Heavener at 0.5" — radar-estimated size aloft.
The Sep 21, 2026 convective day was bigger than Heavener: the same system put hail over 498 other tracked cities, 12 of them in Oklahoma. Nearest: Hatfield (21 miles south, up to 0.75"); Smithville (24 miles southwest, up to 0.5"); Mena (27 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 11 Heavener 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 Heavener. 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.
Below the severe threshold
What 0.5" hail means for Heavener 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.
