Evidence / storm surfaces
How Cookson saw the hail — from two instruments
Aug 17, 2026 · Cookson, OK
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 hail size Surface resolved
Estimated size field 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 Aug 17, 2026 — this storm produced no NEXRAD point detections over Cookson, so there is one map to show, not two.
The storm in context
Where Aug 17, 2026 sits in Cookson's hail record.
This was Cookson's 4th recorded hail day, arriving 19 days after the Jul 29, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Cookson at 0.5" — radar-estimated size aloft.
The Aug 17, 2026 convective day was bigger than Cookson: the same system put hail over 428 other tracked cities, 12 of them in Oklahoma. Nearest: Tahlequah (14 miles north, up to 1.25"); Sallisaw (16 miles southeast, up to 0.75"); Stilwell (17 miles east, up to 1.25").
These maps are stills. In the app this date is one of 4 Cookson 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
1 report filed with the NWS
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.
Wind reports
1 reportBelow the severe threshold
What 0.5" hail means for Cookson 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 18, 2026.
