Evidence / storm surfaces
How Red Oak 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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
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.
The storm in context
Where Aug 4, 2026 sits in Red Oak's hail record.
This was Red Oak's 15th recorded hail day, arriving 33 days after the Jul 2, 2026 storm. By severity it ranks 4th of the 17 storms we have logged here. Radar put the day's largest stone over Red Oak at 2" — radar-estimated size aloft.
The Aug 4, 2026 convective day was bigger than Red Oak: the same system put hail over 131 other tracked cities, 43 of them in Iowa. Nearest: Stanton (9 miles northeast, up to 1.5"); Villisca (10 miles east, up to 1.5"); Imogene (10 miles west, up to 1.25").
These maps are stills. In the app this date is one of 17 Red Oak 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.
Nobody on the ground filed a report over Red Oak 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.
Severe hail signal
What 2" hail means for Red Oak roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$92M
Potential roof exposure — 7,667 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 38 jobs
- Illustrative work
- ~$570K
Close just 0.5% of the 7,667 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 $1,610 on top of the $150 plan.
