Evidence / storm surfaces
How Sioux Center 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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
The storm in context
Where Jul 4, 2026 sits in Sioux Center's hail record.
This was Sioux Center's 7th recorded hail day, arriving 2 days after the Jul 2, 2026 storm. By severity it ranks 7th of the 11 storms we have logged here. Radar put the day's largest stone over Sioux Center at 1" — the largest NEXRAD radar signature.
The Jul 4, 2026 convective day was bigger than Sioux Center: the same system put hail over 2,035 other tracked cities, 57 of them in Iowa. Nearest: Rock Valley (9 miles northwest, up to 1"); Hull (9 miles northeast, up to 1"); Ireton (13 miles southwest, up to 1").
These maps are stills. In the app this date is one of 11 Sioux Center 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 Sioux Center 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.
Damage-capable hail signal
What 1" hail means for Sioux Center roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$5.2M
Potential roof exposure — 436 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 436 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 $92 on top of the $150 plan.
