Evidence / storm surfaces
How Flat Rock saw the hail — from two instruments
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.
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 Mar 22, 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 22, 2026 sits in Flat Rock's hail record.
This was Flat Rock's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 3 storms we have logged here. Radar put the day's largest stone over Flat Rock at 0" — radar-estimated size aloft.
The Mar 22, 2026 convective day was bigger than Flat Rock: the same system put hail over 409 other tracked cities, 130 of them in Indiana. Nearest: Edinburgh (5 miles west, up to 0"); Saint Paul (11 miles east, up to 0"); Columbus (14 miles south, up to 1").
These maps are stills. In the app this date is one of 3 Flat Rock 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.
Nobody on the ground filed a report over Flat Rock for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Below the severe threshold
What 0" hail means for Flat Rock 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.
