Evidence / storm surfaces
How Louisville saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
Where Mar 22, 2026 sits in Louisville's hail record.
This was Louisville's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 13th of the 15 storms we have logged here. Radar put the day's largest stone over Louisville at 0" — radar-estimated size aloft.
The Mar 22, 2026 convective day was bigger than Louisville: the same system put hail over 409 other tracked cities, 5 of them in Kentucky. Nearest: Goshen (13 miles northwest, up to 0"); Westport (14 miles north, up to 0"); Campbellsburg (18 miles northeast, up to 0").
These maps are stills. In the app this date is one of 15 Louisville 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 Louisville 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 Louisville 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.
