Evidence / storm surfaces
How Garrison saw the hail — from two instruments
Jun 9, 2026 · Garrison, ND
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
NEXRAD radar signatures Surface resolved
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

The storm in context
Where Jun 9, 2026 sits in Garrison's hail record.
This was Garrison's 3rd recorded hail day, arriving 2 days after the Jun 7, 2026 storm. By severity it ranks 3rd of the 11 storms we have logged here. Radar put the day's largest stone over Garrison at 1.5" — the largest NEXRAD radar signature.
The Jun 9, 2026 convective day was bigger than Garrison: the same system put hail over 646 other tracked cities, 110 of them in North Dakota. Nearest: Coleharbor (10 miles south, up to 1.75"); Max (14 miles northeast, up to 1.25"); Underwood (17 miles southeast, up to 1.75").
These maps are stills. In the app this date is one of 11 Garrison 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.

High damage potential
What 1.5" hail means for Garrison 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 8, 2026.
