Hail in Dike Apr 14, 2026

The radar-estimated size surface caught this storm, reaching 2.25" aloft. NEXRAD logged no point detections over Dike this day. At 2.25" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Two ways to read the storm

How Dike saw the hail — from two instruments

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 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 2.25"

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

The storm in context

Where Apr 14, 2026 sits in Dike's hail record

This was Dike's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Dike at 2.25" — radar-estimated size aloft.

The Apr 14, 2026 convective day was bigger than Dike: the same system put hail over 476 other tracked cities, 143 of them in Iowa. Nearest: Parkersburg (7 miles north, up to 1.5"); Holland (9 miles southwest, up to 2"); New Hartford (9 miles northeast, up to 0.5").

These maps are stills from Dike'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.

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.

The National Weather Service logged no spotter reports for this storm over Dike. 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.

Severe, roof-replacing hail

What 2.25" hail means for Dike 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 Dike

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 2, 2026.
