How Windom saw the hail — from two instruments

Jun 23, 2026 · Windom, MN

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.

Radar-estimated hail-size map of the storm over Windom, MN on Jun 23, 2026 Estimated size field

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 0.5"

Only the radar-estimated size surface resolved for Jun 23, 2026 — this storm produced no NEXRAD point detections over Windom, so there is one map to show, not two.

The storm in context

Where Jun 23, 2026 sits in Windom's hail record.

This was Windom's 4th recorded hail day, arriving 29 days after the May 25, 2026 storm. By severity it ranks 10th of the 11 storms we have logged here. Radar put the day's largest stone over Windom at 0.5" — radar-estimated size aloft.

The Jun 23, 2026 convective day was bigger than Windom: the same system put hail over 330 other tracked cities, 47 of them in Minnesota. Nearest: Heron Lake (20 miles southwest, up to 0.5"); Morton (35 miles north, up to 1"); Redwood Falls (35 miles north, up to 1").

These maps are stills. In the app this date is one of 11 Windom 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 Windom, 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.

Below the severe threshold

What 0.5" hail means for Windom roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

43 homes × $12,000 avg. claim

Potential roof exposure

$516K

Potential roof exposure — 43 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.
