Two ways to read the storm

How Coggon 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-estimated hail size
Radar-estimated hail-size map of the storm over Coggon, IA on Apr 15, 2026

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.

Max size 0.5"

Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Coggon, so there is one map to show, not two.

The storm in context

Where Apr 15, 2026 sits in Coggon's hail record

This was Coggon's 2nd recorded hail day, arriving 1 day after the Apr 14, 2026 storm. By severity it ranks 5th of the 5 storms we have logged here. Radar put the day's largest stone over Coggon at 0.5" — radar-estimated size aloft.

The Apr 15, 2026 convective day was bigger than Coggon: the same system put hail over 425 other tracked cities, 127 of them in Iowa. Nearest: Masonville (7 miles north, up to 1"); Winthrop (10 miles northwest, up to 1"); Manchester (12 miles northeast, up to 0.75").

These maps are stills from Coggon's Apr 15, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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 Coggon 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.

Below the severe threshold

What 0.5" hail means for Coggon roofs

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.

What this storm is worth to a roofer

$9.4M

Potential roof exposure — 786 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Coggon

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 surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
