Evidence / storm surfaces
How Winterset saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Aug 13, 2026 sits in Winterset's hail record.
This was Winterset's 14th recorded hail day, arriving 17 days after the Jul 27, 2026 storm. By severity it ranks 5th of the 15 storms we have logged here. Radar put the day's largest stone over Winterset at 1" — radar-estimated size aloft.
The Aug 13, 2026 convective day was bigger than Winterset: the same system put hail over 437 other tracked cities, 46 of them in Iowa. Nearest: Van Meter (10 miles northeast, up to 0.5"); Lorimor (14 miles south, up to 0.5"); Saint Charles (15 miles southeast, up to 0.75").
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
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 Winterset 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 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.
Potential roof exposure
$34M
Potential roof exposure — 2,846 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 14 jobs
- Illustrative work
- ~$210K
Close just 0.5% of the 2,846 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 $598 on top of the $150 plan.
