Evidence / storm surfaces
How Hennessey 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 signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for May 31, 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 31, 2026 sits in Hennessey's hail record.
This was Hennessey's 11th recorded hail day, arriving 2 days after the May 29, 2026 storm. By severity it ranks 10th of the 17 storms we have logged here. Radar put the day's largest stone over Hennessey at 0.75" — the largest NEXRAD radar signature.
The May 31, 2026 convective day was bigger than Hennessey: the same system put hail over 637 other tracked cities, 13 of them in Oklahoma. Nearest: Longdale (25 miles west, up to 4"); Seiling (33 miles west, up to 4"); Geary (36 miles southwest, up to 0").
These maps are stills. In the app this date is one of 17 Hennessey 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 Hennessey. 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.
Near the severe threshold
What 0.75" hail means for Hennessey roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
