Evidence / storm surfaces

How Hiawatha saw the hail — from two instruments

Jun 4, 2026 · Hiawatha, KS

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-signature map of the hail storm over Hiawatha, KS on Jun 4, 2026 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
Radar-estimated hail-size map of the storm over Hiawatha, KS on Jun 4, 2026 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 Jun 4, 2026 sits in Hiawatha's hail record.

This was Hiawatha's 12th recorded hail day, arriving 5 days after the May 30, 2026 storm. By severity it ranks 17th of the 20 storms we have logged here. Radar put the day's largest stone over Hiawatha at 1" — the largest NEXRAD radar signature.

The Jun 4, 2026 convective day was bigger than Hiawatha: the same system put hail over 241 other tracked cities, 57 of them in Kansas. Nearest: Morrill (9 miles southwest, up to 1"); Sabetha (11 miles west, up to 1.75"); Dawson (13 miles northwest, up to 1.75").

These maps are stills. In the app this date is one of 20 Hiawatha 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 Hiawatha 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.

Damage-capable hail signal

What 1" hail means for Hiawatha roofs.

Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

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 14, 2026.
