Evidence / storm surfaces

How Winterset saw the hail — from two instruments

Jul 3, 2026 · Winterset, IA

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.

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.

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 Jul 3, 2026 sits in Winterset's hail record.

This was Winterset's 10th recorded hail day, arriving 22 days after the Jun 11, 2026 storm. By severity it ranks 9th of the 15 storms we have logged here. Radar put the day's largest stone over Winterset at 1" — the largest NEXRAD radar signature.

The Jul 3, 2026 convective day was bigger than Winterset: the same system put hail over 1,885 other tracked cities, 182 of them in Iowa. Nearest: Dexter (8 miles west, up to 2.5"); Earlham (10 miles northwest, up to 2.5"); Van Meter (10 miles northeast, up to 1").

These maps are stills. In the app this date is one of 15 Winterset 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

No reports filed with the NWS

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 Winterset. 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.

Damage-capable hail signal

What 1" hail means for Winterset 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.

136 homes × $12,000 avg. claim

Potential roof exposure

$1.6M

Potential roof exposure — 136 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 136 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 $29 on top of the $150 plan.

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 9, 2026.
