How Earlham saw the hail — from two instruments

Apr 23, 2026 · Earlham, IA

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.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

The storm in context

Where Apr 23, 2026 sits in Earlham's hail record.

This was Earlham's 4th recorded hail day, arriving 8 days after the Apr 15, 2026 storm. By severity it ranks 4th of the 10 storms we have logged here. Radar put the day's largest stone over Earlham at 1" — the largest NEXRAD radar signature.

The Apr 23, 2026 convective day was bigger than Earlham: the same system put hail over 703 other tracked cities, 252 of them in Iowa. Nearest: Stuart (6 miles northwest, up to 1.25"); Dexter (7 miles south, up to 1"); Redfield (7 miles north, up to 0.5").

These maps are stills. In the app this date is one of 10 Earlham 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.

Nobody on the ground filed a report over Earlham 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 Earlham 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.

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 Aug 3, 2026.
