Positive tilted, it is going to suffer from some of the same things this system is suffering from, especially if that northern piece speeds up. Which it more than likely should.
Another issue with the Euro compared to other models is the piece dropping in from Montana which helps kick out the southern stream piece mysteriously weakens in Colorado right as it is about to kick the system out, no other model is doing that.
The Euro I believe is too far south with the low, just too wonky with the track with a couple turns east through the day on Wednesday. It is struggling with convection created vorticity and not latching to the main trough ejecting out of the plains itself.
Isn't it crazy we are saying things like this literally less than 48 hours before flakes fly. Anyone who pimps out that models are better now needs to look at this winter deeply.
A streak Detroit is running right now is no high under 25 for the winter so far. That might end Friday though. Pretty incredible when you think about it.
The southern piece is in the US and has been for a couple days so if there will be any sampling surprises it will be with the northern stream and that has been trending positively all day. Also the window is closing as this is rapidly approaching
Northern stream came in weaker and flatter, allowed for better phasing as the southern piece came northeast. That would be one way to overcome the northern stream issues.
Typically I would say that this is DOA, but with that northern stream piece being so significant and large in size it leads me to take pause that it could be a bit slower than projected.
