Evidence / storm surfaces
How Diagonal saw the hail — from two instruments
Sep 6, 2026 · Diagonal, IA
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
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
1.5"
Only the radar-estimated size surface resolved for Sep 6, 2026 — this storm produced no NEXRAD point detections over Diagonal, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Diagonal's hail record.
This was Diagonal's 10th recorded hail day, arriving 33 days after the Aug 4, 2026 storm. By severity it ranks 3rd of the 10 storms we have logged here. Radar put the day's largest stone over Diagonal at 1.5" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Diagonal: the same system put hail over 608 other tracked cities, 72 of them in Iowa. Nearest: Clearfield (5 miles west, up to 1.25"); Benton (7 miles south, up to 1.5"); Lenox (13 miles northwest, up to 1").
These maps are stills. In the app this date is one of 10 Diagonal 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 Diagonal 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 7, 2026.
