Hail in Arcadia Apr 13, 2026

Both radar surfaces caught this storm: NEXRAD logged 3 hail signatures up to 2.75", and the radar-estimated size reached 2" aloft. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Two ways to read the storm

How Arcadia 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.

NEXRAD radar signatures
NEXRAD radar-signature map of the hail storm over Arcadia, WI on Apr 13, 2026

NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

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

The storm in context

Where Apr 13, 2026 sits in Arcadia's hail record

This was Arcadia's 2nd recorded hail day, arriving 14 days after the Mar 30, 2026 storm. By severity it ranks 2nd of the 11 storms we have logged here. Radar put the day's largest stone over Arcadia at 2.75" — the largest NEXRAD radar signature.

The Apr 13, 2026 convective day was bigger than Arcadia: the same system put hail over 467 other tracked cities, 108 of them in Wisconsin. Nearest: Independence (7 miles north, up to 2"); Blair (10 miles northeast, up to 2"); Ettrick (14 miles southeast, up to 2").

These maps are stills from Arcadia's Apr 13, 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.

No ground reports were filed with the National Weather Service for this storm over Arcadia. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Severe, roof-replacing hail

What 2.75" hail means for Arcadia 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.

What this storm is worth to a roofer

$588K

Potential roof exposure — 49 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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 Arcadia

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.
