Evidence / storm surfaces

How Muscatine saw the hail — from two instruments

Mar 26, 2026 · Muscatine, 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.

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.

Max size 0" Detections 0

Only the NEXRAD radar-signature surface resolved for Mar 26, 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 Mar 26, 2026 sits in Muscatine's hail record.

This was Muscatine's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 14th of the 15 storms we have logged here. Radar put the day's largest stone over Muscatine at 0" — radar-estimated size aloft.

The Mar 26, 2026 convective day was bigger than Muscatine: the same system put hail over 316 other tracked cities, 10 of them in Iowa. Nearest: Joy (10 miles east, up to 0"); Keithsburg (17 miles southeast, up to 0"); Oakville (21 miles south, up to 0").

These maps are stills. In the app this date is one of 15 Muscatine 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.

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

Below the severe threshold

What 0" hail means for Muscatine 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 Aug 13, 2026.
