Evidence / storm surfaces
How Douds 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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for Mar 31, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 31, 2026 sits in Douds's hail record.
This was Douds's 3rd recorded hail day, arriving 21 days after the Mar 10, 2026 storm. By severity it ranks 6th of the 7 storms we have logged here. Radar put the day's largest stone over Douds at 0.75" — the largest NEXRAD radar signature.
The Mar 31, 2026 convective day was bigger than Douds: the same system put hail over 522 other tracked cities, 24 of them in Iowa. Nearest: Fairfield (15 miles north, up to 1"); Batavia (17 miles northwest, up to 1.25"); Eldon (17 miles northwest, up to 1.5").

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 Douds. 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 Douds 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.

Potential roof exposure
$2.5M
Potential roof exposure — 208 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs

- ~$15K
Close just 0.5% of the 208 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.
