Evidence / storm surfaces
How Louisville saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for Jun 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 Jun 26, 2026 sits in Louisville's hail record.
This was Louisville's 7th recorded hail day, arriving 15 days after the Jun 11, 2026 storm. 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 Jun 26, 2026 convective day was bigger than Louisville: the same system put hail over 440 other tracked cities, 8 of them in Kentucky. Nearest: Salt Lick (100 miles east, up to 1"); Campton (111 miles east, up to 1.5"); Blaine (136 miles east, up to 1").
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.
The National Weather Service logged no spotter reports for this storm over Louisville. 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 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.
