The first snowstorm of the season produced a Blizzard Warning for much of that area on Wednesday and Thursday.
The National Weather Service says Bismarck has had 24 inches of snow, Steel 22", Mandan 21", and Devils Lake 12.5". Grand Forks is at 9.1" and Roseau at 7.5".
A Winter Weather Advisory remains in place for the northern third of Minnesota until 9:00 a.m. Friday. Additional snow accumulations should be less than an inch. However, 40 mile an hour winds will blow the snow around that has already fallen.
North Dakota is being subjected to a descending plume of cold Artic air that is heading towards Florida, hence the heavy snow fall there.
The Jetstream follows the fringes of this plume and start to travel North as it passes the lowest point of cold air, so dragging warm air up from the equator, hence I had a wonderful sunny day and temperatures up to 17 degrees in November.
