Evidence / storm surfaces
How Chester saw the hail — from two instruments
Jul 4, 2026 · Chester, 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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved

The storm in context
Where Jul 4, 2026 sits in Chester's hail record.
This was Chester's 8th recorded hail day, arriving 8 days after the Jun 26, 2026 storm. By severity it ranks 1st of the 8 storms we have logged here. Radar put the day's largest stone over Chester at 4" — the largest NEXRAD radar signature.
The Jul 4, 2026 convective day was bigger than Chester: the same system put hail over 2,035 other tracked cities, 231 of them in Oklahoma. Nearest: Mutual (11 miles west, up to 4"); Waynoka (14 miles north, up to 3.25"); Fairview (14 miles east, up to 2").

Reports came from Seiling and Orion — beyond Chester itself.
Severe hail signal
What 4" hail means for Chester roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 3, 2026.
