Evidence / storm surfaces

How Winterset saw the hail — from two instruments

Apr 14, 2026 · Winterset, IA

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Winterset, IA on Apr 14, 2026 Estimated size field

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 0.75"

Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Winterset, so there is one map to show, not two.

The storm in context

Where Apr 14, 2026 sits in Winterset's hail record.

This was Winterset's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 6th of the 15 storms we have logged here. Radar put the day's largest stone over Winterset at 0.75" — radar-estimated size aloft.

The Apr 14, 2026 convective day was bigger than Winterset: the same system put hail over 476 other tracked cities, 143 of them in Iowa. Nearest: Van Meter (10 miles northeast, up to 0.75"); Earlham (10 miles northwest, up to 0.5"); Stuart (17 miles northwest, up to 0.5").

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.

The National Weather Service logged no spotter reports for this storm over Winterset. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Near the severe threshold

What 0.75" hail means for Winterset 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.

3,167 homes × $12,000 avg. claim

Potential roof exposure

$38M

Potential roof exposure — 3,167 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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.
