Evidence / storm surfaces
How Arcadia 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 Aug 18, 2026 — this storm produced no NEXRAD point detections over Arcadia, so there is one map to show, not two.
The storm in context
Where Aug 18, 2026 sits in Arcadia's hail record.
This was Arcadia's 13th recorded hail day, arriving 10 days after the Aug 8, 2026 storm. By severity it ranks 8th of the 14 storms we have logged here. Radar put the day's largest stone over Arcadia at 0.5" — radar-estimated size aloft.
The Aug 18, 2026 convective day was bigger than Arcadia: the same system put hail over 309 other tracked cities, 36 of them in Wisconsin. Nearest: Fountain City (11 miles southwest, up to 0.5"); Trempealeau (14 miles south, up to 1.25"); Minnesota City (14 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 14 Arcadia 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.
For this storm over Arcadia, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Arcadia 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
$17M
Potential roof exposure — 1,430 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 7 jobs
- Illustrative work
- ~$105K
Close just 0.5% of the 1,430 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 $300 on top of the $150 plan.
