How Maddock 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-estimated hail size
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 Jul 16, 2026 — this storm produced no NEXRAD point detections over Maddock, so there is one map to show, not two.
Where Jul 16, 2026 sits in Maddock's hail record
This was Maddock's 6th recorded hail day, arriving 7 days after the Jul 9, 2026 storm. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Maddock at 1.5" — radar-estimated size aloft.
The Jul 16, 2026 convective day was bigger than Maddock: the same system put hail over 206 other tracked cities, 16 of them in North Dakota. Nearest: Sheyenne (7 miles east, up to 1.25"); Cathay (11 miles south, up to 1.25"); New Rockford (12 miles southeast, up to 1.25").
These maps are stills from Maddock's Jul 16, 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 1.5" hail means for Maddock roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
What this storm is worth to a roofer

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.
