How Shenandoah saw the hail — from two instruments

Apr 23, 2026 · Shenandoah, IA

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

The storm in context

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

This was Shenandoah's 4th recorded hail day, arriving 9 days after the Apr 14, 2026 storm. By severity it ranks 2nd of the 17 storms we have logged here. Radar put the day's largest stone over Shenandoah at 1.75" — the largest NEXRAD radar signature.

The Apr 23, 2026 convective day was bigger than Shenandoah: the same system put hail over 703 other tracked cities, 252 of them in Iowa. Nearest: Northboro (5 miles east, up to 1"); Hamburg (8 miles west, up to 2"); Rock Port (9 miles southwest, up to 2.25").

These maps are stills. In the app this date is one of 17 Shenandoah 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.

For this storm over Shenandoah, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

High damage potential

What 1.75" hail means for Shenandoah roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 Sep 15, 2026.
