Hail in Franklin Jul 21, 2026

Hit 13 days ago

Both radar surfaces caught this storm: NEXRAD logged 100 hail signatures up to 3.75", and the radar-estimated size reached 1.5" aloft. At 3.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Two ways to read the storm

How Franklin 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.

NEXRAD radar signatures
NEXRAD radar-signature map of the hail storm over Franklin, KY on Jul 21, 2026

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.

Where Jul 21, 2026 sits in Franklin's hail record

This was Franklin's 4th recorded hail day, arriving 11 days after the Jul 10, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Franklin at 3.75" — the largest NEXRAD radar signature.

The Jul 21, 2026 convective day was bigger than Franklin: the same system put hail over 703 other tracked cities, 101 of them in Kentucky. Nearest: Woodburn (4 miles northeast, up to 3"); Rockfield (11 miles north, up to 2.5"); Orlinda (13 miles southwest, up to 1.75").

These maps are stills from Franklin's Jul 21, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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 Franklin 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.

Severe, roof-replacing hail

What 3.75" hail means for Franklin roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

What this storm is worth to a roofer

$45M

Potential roof exposure — 3,778 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Franklin

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
