Hail in Holland Apr 14, 2026
The radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Holland this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Holland 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-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Holland, so there is one map to show, not two.
Where Apr 14, 2026 sits in Holland's hail record
This was Holland's 2nd recorded hail day, arriving 11 days after the Apr 3, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Holland at 2" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Holland: the same system put hail over 476 other tracked cities, 143 of them in Iowa. Nearest: Grundy Center (7 miles south, up to 2.25"); Dike (9 miles northeast, up to 2.25"); Wellsburg (9 miles northwest, up to 2").
These maps are stills from Holland's Apr 14, 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.
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.
Hail reports
1 reportWhat 2" hail means for Holland roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

Other storms in Holland
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.
