Hail in Jamestown Jul 3, 2026
Hit 31 days agoBoth radar surfaces caught this storm: NEXRAD logged 60 hail signatures up to 3", and the radar-estimated size reached 1.5" aloft. At 3" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Jamestown 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.
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
Where Jul 3, 2026 sits in Jamestown's hail record
This was Jamestown's 2nd recorded hail day, arriving 44 days after the May 20, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Jamestown at 3" — the largest NEXRAD radar signature.
The Jul 3, 2026 convective day was bigger than Jamestown: the same system put hail over 1,885 other tracked cities, 176 of them in Tennessee. Nearest: Sunbright (15 miles southeast, up to 1.75"); Lancing (19 miles southeast, up to 2"); Robbins (19 miles east, up to 1.75").
These maps are stills from Jamestown's Jul 3, 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.
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.
For this storm over Jamestown, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
What 3" hail means for Jamestown 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.
