Two ways to read the storm

How Westby saw the hail — from two instruments

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

The storm in context

Where Jun 5, 2026 sits in Westby's hail record

This was Westby's 3rd recorded hail day, arriving 18 days after the May 18, 2026 storm. By severity it ranks 4th of the 5 storms we have logged here. Radar put the day's largest stone over Westby at 0.5" — radar-estimated size aloft.

The Jun 5, 2026 convective day was bigger than Westby: the same system put hail over 440 other tracked cities, 44 of them in Wisconsin. Nearest: Coon Valley (10 miles northwest, up to 0.5"); Chaseburg (12 miles west, up to 1"); Sparta (16 miles northeast, up to 1").

These maps are stills from Westby's Jun 5, 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 Westby 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.

Below the severe threshold

What 0.5" hail means for Westby roofs

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.

What this storm is worth to a roofer

$456K

Potential roof exposure — 38 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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 Westby

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.
