Evidence / storm surfaces
How Manitowoc 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.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Apr 13, 2026 — this storm produced no NEXRAD point detections over Manitowoc, so there is one map to show, not two.
The storm in context
Where Apr 13, 2026 sits in Manitowoc's hail record.
This was Manitowoc's 3rd recorded hail day, arriving 13 days after the Mar 31, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Manitowoc at 0.5" — radar-estimated size aloft.
The Apr 13, 2026 convective day was bigger than Manitowoc: the same system put hail over 467 other tracked cities, 108 of them in Wisconsin. Nearest: Denmark (15 miles north, up to 0.75"); Kewaunee (23 miles northeast, up to 0.5"); De Pere (24 miles northwest, up to 0.5").
These maps are stills. In the app this date is one of 4 Manitowoc 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
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 Manitowoc 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 Manitowoc 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.6M
Potential roof exposure — 135 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 135 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.
Claim window
April 2028
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.
Names and phones for every home in the footprint: at most $28 on top of the $150 plan.
