Evidence / storm surfaces
How Pettibone saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
Where Jun 29, 2026 sits in Pettibone's hail record.
This was Pettibone's 2nd recorded hail day, arriving 27 days after the Jun 2, 2026 storm. By severity it ranks 6th of the 8 storms we have logged here. Radar put the day's largest stone over Pettibone at 1.75" — the largest NEXRAD radar signature.
The Jun 29, 2026 convective day was bigger than Pettibone: the same system put hail over 702 other tracked cities, 96 of them in North Dakota. Nearest: Robinson (10 miles southwest, up to 1.75"); Woodworth (15 miles east, up to 1.25"); Tuttle (21 miles southwest, up to 3").
These maps are stills. In the app this date is one of 8 Pettibone 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.

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.
Hail reports
1 reportHigh damage potential
What 1.75" hail means for Pettibone 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.
