Evidence / storm surfaces
How Denmark saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Apr 13, 2026 — this storm produced no NEXRAD point detections over Denmark, so there is one map to show, not two.
The storm in context
Where Apr 13, 2026 sits in Denmark's hail record.
This was Denmark's 2nd recorded hail day, arriving 13 days after the Mar 31, 2026 storm. By severity it ranks 3rd of the 5 storms we have logged here. Radar put the day's largest stone over Denmark at 0.75" — radar-estimated size aloft.
The Apr 13, 2026 convective day was bigger than Denmark: the same system put hail over 467 other tracked cities, 108 of them in Wisconsin. Nearest: Green Bay (12 miles northwest, up to 0.5"); New Franken (14 miles north, up to 0.5"); Manitowoc (15 miles south, up to 0.5").

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.
The National Weather Service logged no spotter reports for this storm over Denmark. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Near the severe threshold
What 0.75" hail means for Denmark roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.4M
Potential roof exposure — 365 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 365 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 $77 on top of the $150 plan.
