Evidence / storm surfaces
How Rocklake 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 Rocklake, so there is one map to show, not two.
The storm in context
Where Jan 2, 2026 sits in Rocklake's hail record.
This was Rocklake's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Rocklake at 1.75" — radar-estimated size aloft.
The Jan 2, 2026 convective day was bigger than Rocklake: the same system put hail over 21 other tracked cities, 19 of them in North Dakota. Nearest: Calvin (14 miles east, up to 1.5"); Munich (17 miles southeast, up to 1.75"); Hannah (21 miles east, up to 1.75").

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 Rocklake 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.
High damage potential
What 1.75" hail means for Rocklake roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.
