I have to include a hemispheric image in order to better define this, but, to begin there is a circulation center that is beginning to consolidate in a central rotation found at the border between Canada and North Dakota.
I was more defuse with less punch about an hour or so ago, but, the center of the circulation is taking shape. I think we are going to see high velocity winds in several forms tonight and tomorrow.

There is a reason why the central circulation is developing at the border of ND and Canada. It is the fast moving question shaped air mass off the Pacific Coast. It is probably easier to see in Water Vapor. But, that Pacific Air Mass is hauling hot water vapor from the Equatorial Air Mass and taking it right into the Arctic Air Mass. The velocity is really picking up speed and causing the circulation center over ND to take on definition.

I don't like it. There is not only a lot of hot and cold mixing that will cause turbulence, but, there is a variety of wind velocities. There is most likely going to be straight line winds along with what is not developing in the ND/Canada border, namely a vortex.
Optimistically, the hot and cold mixing over the Pacific might blunt the turbulence, but, the sheer mass of that Pacific system and its affect on the system at the Canada/ND border spells trouble to me. Either way the Enhanced Infared is showing intermittent consolidation of activity and that can't be good, unless it continues to consolidate and disperse. It might be the Pacific system may tame what is occurring over the continent and the nation will only have to deal with winds. Let's hope so, but, the air mass by size and density that has resulted in that 'pushing' dynamic is a worry.
At this moment the Graphton, North Dakota / Winnepeg, Mannitoba, Canada region is seeking sincere central rotation of that system. It is moving east, northeast, but, only slightly.
