Evidence / storm surfaces
How Halliday 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.
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.
Only the radar-estimated size surface resolved for Aug 30, 2026 — this storm produced no NEXRAD point detections over Halliday, so there is one map to show, not two.
The storm in context
Where Aug 30, 2026 sits in Halliday's hail record.
This was Halliday's 6th recorded hail day, arriving 56 days after the Jul 5, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Halliday at 0.75" — radar-estimated size aloft.
The Aug 30, 2026 convective day was bigger than Halliday: the same system put hail over 117 other tracked cities, 42 of them in North Dakota. Nearest: Dodge (10 miles east, up to 0.5"); Dunn Center (16 miles northwest, up to 1"); Zap (24 miles southeast, up to 0.75").

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.
No ground reports were filed with the National Weather Service for this storm over Halliday. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Halliday roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
