Evidence / storm surfaces
How Knox saw the hail — from two instruments
Aug 11, 2026 · Knox, IN
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

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 Aug 11, 2026 — this storm produced no NEXRAD point detections over Knox, so there is one map to show, not two.
The storm in context
Where Aug 11, 2026 sits in Knox's hail record.
This was Knox's 5th recorded hail day, arriving 24 days after the Jul 18, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Knox at 1.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Knox: the same system put hail over 1,041 other tracked cities, 170 of them in Indiana. Nearest: Hamlet (7 miles north, up to 0.75"); North Judson (12 miles southwest, up to 1.5"); La Crosse (13 miles west, up to 1.5").
These maps are stills. In the app this date is one of 5 Knox 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.

How the storm moved

High damage potential
What 1.5" hail means for Knox 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 12, 2026.
