Evidence / storm surfaces

How Corning saw the hail — from two instruments

Jun 4, 2026 · Corning, IA

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

The storm in context

Where Jun 4, 2026 sits in Corning's hail record.

This was Corning's 11th recorded hail day, arriving 3 days after the Jun 1, 2026 storm. By severity it ranks 12th of the 18 storms we have logged here. Radar put the day's largest stone over Corning at 0.75" — the largest NEXRAD radar signature.

The Jun 4, 2026 convective day was bigger than Corning: the same system put hail over 241 other tracked cities. Nearest: Nebraska City (59 miles southwest, up to 1"); King City (64 miles south, up to 2.5"); Mc Fall (67 miles southeast, up to 1.75").

These maps are stills. In the app this date is one of 18 Corning 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.

The National Weather Service logged no spotter reports for this storm over Corning. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Near the severe threshold

What 0.75" hail means for Corning roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

What this storm is worth to a roofer.

11 homes × $12,000 avg. claim

Potential roof exposure

$132K

Potential roof exposure — 11 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Claim window

June 2028

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.

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.
