How Shenandoah saw the hail — from two instruments

Apr 9, 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.

NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.

Only the NEXRAD radar-signature surface resolved for Apr 9, 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 Apr 9, 2026 sits in Shenandoah's hail record.

This was Shenandoah's 2nd recorded hail day, arriving 35 days after the Mar 5, 2026 storm. By severity it ranks 17th of the 17 storms we have logged here. Radar put the day's largest stone over Shenandoah at 0" — radar-estimated size aloft.

The Apr 9, 2026 convective day was bigger than Shenandoah: the same system put hail over 161 other tracked cities, 14 of them in Iowa. Nearest: Essex (17 miles northeast, up to 0"); Randolph (21 miles north, up to 0"); Sidney (21 miles northwest, up to 0").

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.

Below the severe threshold

What 0" hail means for Shenandoah 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 Sep 15, 2026.
