Evidence / storm surfaces
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.
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 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 5 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 northwest, up to 3"); Adolphus (9 miles southeast, up to 2.5"); Scottsville (9 miles northeast, up to 1").

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 hail signal
What 3.75" hail means for Franklin roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$45M
Potential roof exposure — 3,778 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 19 jobs
- Illustrative work
- ~$285K
Close just 0.5% of the 3,778 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $793 on top of the $150 plan.
