Evidence / storm surfaces
How Royal saw the hail — from two instruments
Jul 4, 2026 · Royal, IA
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.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

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.

The storm in context
Where Jul 4, 2026 sits in Royal's hail record.
This was Royal's 4th recorded hail day, arriving 7 days after the Jun 27, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Royal at 1.5" — the largest NEXRAD radar signature.
The Jul 4, 2026 convective day was bigger than Royal: the same system put hail over 2,035 other tracked cities, 57 of them in Iowa. Nearest: Sioux Rapids (9 miles southeast, up to 0.5"); Greenville (12 miles southeast, up to 0.75"); Hartley (15 miles north, up to 0.5").
These maps are stills. In the app this date is one of 5 Royal 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.

High damage potential
What 1.5" hail means for Royal 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 9, 2026.
