Evidence / storm surfaces
How Granville 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.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Jan 2, 2026 — this storm produced no NEXRAD point detections over Granville, so there is one map to show, not two.
The storm in context
Where Jan 2, 2026 sits in Granville's hail record.
This was Granville's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Granville at 2.25" — radar-estimated size aloft.
The Jan 2, 2026 convective day was bigger than Granville: the same system put hail over 21 other tracked cities, 19 of them in North Dakota. Nearest: Norwich (5 miles west, up to 2.25"); Surrey (12 miles northwest, up to 2.25"); Minot (22 miles west, up to 2.25").

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 Granville 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 2.25" hail means for Granville 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
$2.2M
Potential roof exposure — 185 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 185 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
January 2028
Claims from this storm can typically be filed until around January 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 $39 on top of the $150 plan.
