How Stuart saw the hail — from two instruments

May 15, 2026 · Stuart, 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 — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

The storm in context

Where May 15, 2026 sits in Stuart's hail record.

This was Stuart's 6th recorded hail day, arriving 22 days after the Apr 23, 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 May 15, 2026 convective day was bigger than Stuart: the same system put hail over 444 other tracked cities, 236 of them in Iowa. Nearest: Redfield (6 miles northeast, up to 1.75"); Earlham (6 miles southeast, up to 1"); Casey (11 miles west, up to 1").

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.

For this storm over Stuart, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

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.
