Hail in Bismarck Jul 19, 2026
Hit 15 days agoThe radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Bismarck this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Bismarck saw the hail — from two instruments
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.
Radar-estimated hail size
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.

Only the radar-estimated size surface resolved for Jul 19, 2026 — this storm produced no NEXRAD point detections over Bismarck, so there is one map to show, not two.
Where Jul 19, 2026 sits in Bismarck's hail record
This was Bismarck's 5th recorded hail day, arriving 10 days after the Jul 9, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Bismarck at 2" — radar-estimated size aloft.
The Jul 19, 2026 convective day was bigger than Bismarck: the same system put hail over 351 other tracked cities, 44 of them in North Dakota. Nearest: Baldwin (8 miles northeast, up to 0.5"); Menoken (12 miles east, up to 1.25"); Sterling (20 miles east, up to 1.25").
These maps are stills from Bismarck's Jul 19, 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 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.

How the storm moved
Reports came from Menoken — beyond Bismarck itself.
What 2" hail means for Bismarck roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
What this storm is worth to a roofer
$92M
Potential roof exposure — 7,646 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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.
