Bismarck hail storm history
Burleigh County·NOAA NCEI Storm Events Database·~75-day publication lag
Bismarck and Burleigh County lie in the Missouri River valley of western North Dakota, a corridor where the Missouri Coteau escarpment and dry-line interactions routinely generate hail-producing supercells. The region's geography — elevated terrain meeting flat plains — creates conditions that funnel organized convection through the area during the warm season, making hail damage a recurring risk for homeowners.
Check if your roof was damaged by recent hail
Hail season in Bismarck peaks in June and July, with secondary activity in May and August. During these months, upper-level troughs push organized thunderstorms through the region, and daytime heating over the open plains accelerates storm development on warm afternoons. Hail events in this area range from pea-sized to severe, with documented storms producing hail capable of functional roof damage on all shingle types.
