Evidence / storm surfaces
How Hollis saw the hail — from two instruments
Aug 25, 2026 · Hollis, OK
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size
3"
Only the radar-estimated size surface resolved for Aug 25, 2026 — this storm produced no NEXRAD point detections over Hollis, so there is one map to show, not two.
The storm in context
Where Aug 25, 2026 sits in Hollis's hail record.
This was Hollis's 9th recorded hail day, arriving 52 days after the Jul 4, 2026 storm. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over Hollis at 3" — radar-estimated size aloft.
The Aug 25, 2026 convective day was bigger than Hollis: the same system put hail over 205 other tracked cities, 4 of them in Oklahoma. Nearest: Gould (4 miles southeast, up to 3"); Eldorado (15 miles south, up to 2.25"); Quanah (21 miles south, up to 2.25").
These maps are stills. In the app this date is one of 9 Hollis 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.

Severe hail signal
What 3" hail means for Hollis 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 26, 2026.
