How Holland saw the hail — from two instruments

May 16, 2026 · Holland, 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.

Max size 0" Detections 0

Only the NEXRAD radar-signature surface resolved for May 16, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

The storm in context

Where May 16, 2026 sits in Holland's hail record.

This was Holland's 4th recorded hail day, arriving 29 days after the Apr 17, 2026 storm. By severity it ranks 6th of the 6 storms we have logged here. Radar put the day's largest stone over Holland at 0" — radar-estimated size aloft.

The May 16, 2026 convective day was bigger than Holland: the same system put hail over 711 other tracked cities, 64 of them in Iowa. Nearest: Cedar Falls (12 miles northeast, up to 0.5"); Eldora (17 miles southwest, up to 1"); New Providence (23 miles southwest, up to 1").

These maps are stills. In the app this date is one of 6 Holland 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 Holland. 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.

Below the severe threshold

What 0" hail means for Holland roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 11, 2026.
