Initial thunderstorms developed along a surface trough over northwest North Dakota and moved eastward through northern North Dakota during the afternoon of June 9, producing the first round of severe winds and hail. A more organized complex of severe thunderstorms developed in the evening and overnight hours of June 9, and continued into the early morning of June 10, as a well defined shortwave trough pushed into the region. Extensive damage occurred over parts of far northern North Dakota, particularly in Bottineau County. Wind gusts to around 100 mph in the city of Lansford caused extensive damage to the grain elevator and multiple portable and permanent structures. The largest hail reported was 1.75 inch diameter, and occurred in Divide and Mountrail counties.
