Evidence / storm surfaces
How Villisca saw the hail — from two instruments
Apr 9, 2026 · Villisca, IA
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.
NEXRAD radar signatures Surface resolved
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

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 Villisca's hail record.
This was Villisca's 3rd recorded hail day, arriving 34 days after the Mar 6, 2026 storm. By severity it ranks 11th of the 13 storms we have logged here. Radar put the day's largest stone over Villisca at 0" — radar-estimated size aloft.
The Apr 9, 2026 convective day was bigger than Villisca: the same system put hail over 161 other tracked cities, 14 of them in Iowa. Nearest: Clarinda (7 miles south, up to 0"); Essex (13 miles southwest, up to 0"); Emerson (21 miles northwest, up to 0").
These maps are stills. In the app this date is one of 13 Villisca 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.

Below the severe threshold
What 0" hail means for Villisca 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 7, 2026.
