Evidence / storm surfaces
How Bowman saw the hail — from two instruments
Jun 7, 2026 · Bowman, ND
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Jun 7, 2026 sits in Bowman's hail record.
This was Bowman's 2nd recorded hail day, arriving 5 days after the Jun 2, 2026 storm. By severity it ranks 6th of the 10 storms we have logged here. Radar put the day's largest stone over Bowman at 1.25" — the largest NEXRAD radar signature.
The Jun 7, 2026 convective day was bigger than Bowman: the same system put hail over 237 other tracked cities, 62 of them in North Dakota. Nearest: Reeder (22 miles east, up to 1.25"); Buffalo (37 miles south, up to 4"); Lodgepole (38 miles southeast, up to 1.5").
These maps are stills. In the app this date is one of 10 Bowman 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.

Damage-capable hail signal
What 1.25" hail means for Bowman roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
8 homes × $12,000 avg. claim
Potential roof exposure

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 Aug 24, 2026.
