Evidence / storm surfaces
How Olsburg saw the hail — from two instruments
Sep 19, 2026 · Olsburg, KS
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
1.5"
Only the radar-estimated size surface resolved for Sep 19, 2026 — this storm produced no NEXRAD point detections over Olsburg, so there is one map to show, not two.

Hail reports
1 reportHigh damage potential
What 1.5" hail means for Olsburg 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.
