How Red Oak saw the hail — from two instruments

Jun 6, 2026 · Red Oak, 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.

The storm in context

Where Jun 6, 2026 sits in Red Oak's hail record.

This was Red Oak's 10th recorded hail day, arriving 1 day after the Jun 5, 2026 storm. By severity it ranks 6th of the 17 storms we have logged here. Radar put the day's largest stone over Red Oak at 1.75" — the largest NEXRAD radar signature.

The Jun 6, 2026 convective day was bigger than Red Oak: the same system put hail over 447 other tracked cities, 4 of them in Iowa. Nearest: Elliott (15 miles north, up to 1.5"); Griswold (21 miles north, up to 2"); Corning (22 miles east, up to 1.5").

These maps are stills. In the app this date is one of 17 Red Oak 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

Nobody on the ground filed a report over Red Oak for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

High damage potential

What 1.75" hail means for Red Oak 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.
