Evidence / storm surfaces
How Fairfield 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 Jul 20, 2026 — this storm produced no NEXRAD point detections over Fairfield, so there is one map to show, not two.
The storm in context
Where Jul 20, 2026 sits in Fairfield's hail record.
This was Fairfield's 13th recorded hail day, arriving 17 days after the Jul 3, 2026 storm. By severity it ranks 10th of the 15 storms we have logged here. Radar put the day's largest stone over Fairfield at 0.75" — radar-estimated size aloft.
The Jul 20, 2026 convective day was bigger than Fairfield: the same system put hail over 553 other tracked cities, 178 of them in Iowa. Nearest: Lockridge (5 miles east, up to 0.5"); Brighton (11 miles north, up to 1"); Richland (15 miles north, up to 1").

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.
No ground reports were filed with the National Weather Service for this storm over Fairfield. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Fairfield 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
$8.8M
Potential roof exposure — 731 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 4 jobs
- Illustrative work
- ~$60K
Close just 0.5% of the 731 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
July 2028
Claims from this storm can typically be filed until around July 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 $154 on top of the $150 plan.
