How Mcpherson saw the hail — from two instruments

Sep 19, 2026 · Mcpherson, KS

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
Radar-estimated hail-size map of the storm over Mcpherson, KS on Sep 19, 2026 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 1.75"

Only the radar-estimated size surface resolved for Sep 19, 2026 — this storm produced no NEXRAD point detections over Mcpherson, so there is one map to show, not two.

Reports came from Marquette — beyond Mcpherson itself.

High damage potential

What 1.75" hail means for Mcpherson 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 Sep 20, 2026.
