Evidence / storm surfaces
How Celina saw the hail — from two instruments
Aug 12, 2026 · Celina, OH
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.
Max size
1.5"
Only the radar-estimated size surface resolved for Aug 12, 2026 — this storm produced no NEXRAD point detections over Celina, so there is one map to show, not two.
The storm in context
Where Aug 12, 2026 sits in Celina's hail record.
This was Celina's 7th recorded hail day, arriving 1 day after the Aug 11, 2026 storm. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Celina at 1.5" — radar-estimated size aloft.
The Aug 12, 2026 convective day was bigger than Celina: the same system put hail over 507 other tracked cities, 8 of them in Ohio. Nearest: New Knoxville (19 miles east, up to 1"); Van Wert (19 miles northeast, up to 0.5"); Venedocia (22 miles northeast, up to 0.75").

High damage potential
What 1.5" hail means for Celina roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 13, 2026.
