How Stuart saw the hail — from two instruments

Mar 30, 2026 · Stuart, IA

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

The storm in context

Where Mar 30, 2026 sits in Stuart's hail record.

This was Stuart's 3rd recorded hail day, arriving 24 days after the Mar 6, 2026 storm. By severity it ranks 2nd of the 15 storms we have logged here. Radar put the day's largest stone over Stuart at 1.75" — the largest NEXRAD radar signature.

The Mar 30, 2026 convective day was bigger than Stuart: the same system put hail over 313 other tracked cities, 78 of them in Iowa. Nearest: Redfield (6 miles northeast, up to 1"); Casey (11 miles west, up to 1.75"); Panora (12 miles northwest, up to 1.75").

These maps are stills. In the app this date is one of 15 Stuart 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 Stuart 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 Stuart 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 15, 2026.
