A surface low situated over eastern Montana led to increasing low level moisture over western and central North Dakota. Thunderstorms developed in the late afternoon and early evening as a strong short wave pushed into the area. Some storms over western North Dakota became severe, though a notable slow moving supercell developed near New Town causing significant crop and property damage in that area of Mountrail County and Fort Berthold.
