The 10th most severe storm Norwalk has seen in the last 12 months
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
How Norwalk saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Mar 6, 2026 sits in Norwalk's hail record.
This was Norwalk's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 10th of the 10 storms we have logged here. Radar put the day's largest stone over Norwalk at 0" — radar-estimated size aloft.
The Mar 6, 2026 convective day was bigger than Norwalk: the same system put hail over 486 other tracked cities, 43 of them in Iowa. Nearest: Des Moines (9 miles northwest, up to 0.5"); Cumming (10 miles west, up to 0.5"); Johnston (15 miles north, up to 0.75").
These maps are stills. In the app this date is one of 10 Norwalk 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
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.
No ground reports were filed with the National Weather Service for this storm over Norwalk. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0" hail means for Norwalk 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.
