Evidence / storm surfaces
How Willmar 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 May 24, 2026 — this storm produced no NEXRAD point detections over Willmar, so there is one map to show, not two.
The storm in context
Where May 24, 2026 sits in Willmar's hail record.
This was Willmar's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Willmar at 0.75" — radar-estimated size aloft.
The May 24, 2026 convective day was bigger than Willmar: the same system put hail over 200 other tracked cities, 33 of them in Minnesota. Nearest: Kandiyohi (5 miles east, up to 0.5"); Raymond (14 miles southwest, up to 0.75"); Lake Lillian (15 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.
The National Weather Service logged no spotter reports for this storm over Willmar. 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 Willmar 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
$6.2M
Potential roof exposure — 516 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 3 jobs
- Illustrative work
- ~$45K
Close just 0.5% of the 516 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
May 2028
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
