Two ways to read the storm

How Altoona saw the hail — from two instruments

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.

Radar-estimated hail size
Radar-estimated hail-size map of the storm over Altoona, KS on Jun 16, 2026

Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Max size 1.75"

Only the radar-estimated size surface resolved for Jun 16, 2026 — this storm produced no NEXRAD point detections over Altoona, so there is one map to show, not two.

The storm in context

Where Jun 16, 2026 sits in Altoona's hail record

This was Altoona's 9th recorded hail day, arriving 3 days after the Jun 13, 2026 storm. By severity it ranks 5th of the 11 storms we have logged here. Radar put the day's largest stone over Altoona at 1.75" — radar-estimated size aloft.

The Jun 16, 2026 convective day was bigger than Altoona: the same system put hail over 225 other tracked cities, 30 of them in Kansas. Nearest: Thayer (14 miles east, up to 1.75"); Chanute (16 miles northeast, up to 1.75"); Galesburg (18 miles southeast, up to 1.25").

These maps are stills from Altoona's Jun 16, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

Ground reports

What people on the ground reported

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 Altoona 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.

Widespread claimable damage

What 1.75" hail means for Altoona roofs

At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.

What this storm is worth to a roofer

$3.3M

Potential roof exposure — 274 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 274 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Altoona

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 surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
