How Jamestown 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
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.

Only the NEXRAD radar-signature surface resolved for Jul 24, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
Where Jul 24, 2026 sits in Jamestown's hail record
This was Jamestown's 7th recorded hail day, arriving 15 days after the Jul 9, 2026 storm. By severity it ranks 5th of the 7 storms we have logged here. Radar put the day's largest stone over Jamestown at 0.75" — the largest NEXRAD radar signature.
The Jul 24, 2026 convective day was bigger than Jamestown: the same system put hail over 221 other tracked cities, 69 of them in North Dakota. Nearest: Cleveland (18 miles southwest, up to 1.5"); Montpelier (25 miles south, up to 0.75"); Medina (27 miles west, up to 2.75").
These maps are stills from Jamestown's Jul 24, 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.

Reports came from Buchanan — beyond Jamestown itself.
What 0.75" hail means for Jamestown roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

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.
