Hail in Ponca City Apr 17, 2026

Both radar surfaces caught this storm: NEXRAD logged 28 hail signatures up to 4", and the radar-estimated size reached 2.5" aloft. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

Two ways to read the storm

How Ponca City saw the hail — from two instruments

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.

Severe, roof-replacing hail

What 4" hail means for Ponca City roofs
