Figure 1 depicts the surface observations at 4:00 pm CDT, which shows a low pressure in Western Manitoba with a cold front extending across Southwestern Manitoba and Northwestern North Dakota and a warm front extending across Southern Manitoba. The cold front became the focus for intense supercell thunderstorms in the afternoon and evening hours of July 7th, which ultimately resulted in several tornadoes across North Dakota.
There were a total of 8 tornadoes on this day. Below are the tornadoes that occurred in North Dakota, seemingly from the same supercell:
- Lake Metigoshe, ND EF0 Tornado
- Dunseith, ND EF0 Tornado
- Belcourt, ND EF3 Tornado
- Munich, ND EF1 Tornado
- Munich, ND EF1 Tornado
- Lankin, ND EF0 Tornado
