Evidence / storm surfaces
How Jamestown saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for Jul 2, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jul 2, 2026 sits in Jamestown's hail record.
This was Jamestown's 5th recorded hail day, arriving 3 days after the Jun 29, 2026 storm. By severity it ranks 7th of the 10 storms we have logged here. Radar put the day's largest stone over Jamestown at 0.5" — the largest NEXRAD radar signature.
The Jul 2, 2026 convective day was bigger than Jamestown: the same system put hail over 1,147 other tracked cities, 49 of them in North Dakota. Nearest: Pingree (16 miles northwest, up to 1"); Spiritwood (20 miles east, up to 0.5"); Medina (26 miles west, up to 1").
These maps are stills. In the app this date is one of 10 Jamestown 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 Jamestown 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 0.5" hail means for Jamestown 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$348K
Potential roof exposure — 29 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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 $6 on top of the $150 plan.
