Evidence / storm surfaces
How Lebanon 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.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
The storm in context
Where Jul 21, 2026 sits in Lebanon's hail record.
This was Lebanon's 9th recorded hail day, arriving 2 days after the Jul 19, 2026 storm. By severity it ranks 12th of the 12 storms we have logged here. Radar put the day's largest stone over Lebanon at 0" — radar-estimated size aloft.
The Jul 21, 2026 convective day was bigger than Lebanon: the same system put hail over 703 other tracked cities, 60 of them in Tennessee. Nearest: Alexandria (13 miles southeast, up to 0"); Brush Creek (13 miles southeast, up to 0"); Castalian Springs (15 miles north, up to 1").
These maps are stills. In the app this date is one of 12 Lebanon 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 Lebanon 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 Lebanon 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.
