Hail in Baldwin Apr 17, 2026

Both radar surfaces caught this storm: NEXRAD logged 22 hail signatures up to 2", and the radar-estimated size reached 0.5" aloft. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Two ways to read the storm

How Baldwin 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.

Where Apr 17, 2026 sits in Baldwin's hail record

This was Baldwin's 2nd recorded hail day, arriving 6 days after the Apr 11, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Baldwin at 2" — the largest NEXRAD radar signature.

The Apr 17, 2026 convective day was bigger than Baldwin: the same system put hail over 1,016 other tracked cities, 178 of them in Wisconsin. Nearest: River Falls (10 miles southwest, up to 1"); Roberts (10 miles west, up to 1"); Glenwood City (11 miles northeast, up to 1.5").

These maps are stills from Baldwin's Apr 17, 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 Baldwin 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.

Severe, roof-replacing hail

What 2" hail means for Baldwin roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

Close just 0.5% of the 1,222 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 April 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Baldwin

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.
