Evidence / storm surfaces
How New Lisbon saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over New Lisbon, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in New Lisbon's hail record.
This was New Lisbon's 4th recorded hail day, arriving 129 days after the Apr 14, 2026 storm. By severity it ranks 2nd of the 4 storms we have logged here. Radar put the day's largest stone over New Lisbon at 0.5" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than New Lisbon: the same system put hail over 659 other tracked cities, 19 of them in Wisconsin. Nearest: Grand Marsh (27 miles east, up to 0.5"); Sparta (31 miles west, up to 0.5"); Cazenovia (35 miles south, up to 0.75").

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 New Lisbon 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 New Lisbon 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
$3.4M
Potential roof exposure — 281 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 281 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
August 2028
Claims from this storm can typically be filed until around August 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 $59 on top of the $150 plan.
