The evolution is generally similar to 12z. The low track is further NW- pretty obvious why comparing the upper levels between the 2 runs.
Too far out to care much. Onward.
Until there is a persistent discrete threat, this is probably about as good as it gets at this range over a 5 or 7 day window. Problem is it can go right back to looking paltry the next run, and it really means nothing wrt the upcoming potential.
Those maps are what they are. Not worth much other than maybe a relative indicator between runs at this range. Supports the idea of an active period with cold in place.
I made reference to the Jan 6-10 period on my post this morning. That looks active on the 12z run as well. Yes those appear to be the 2 windows, give or take.
A weenie might want to check the snow map for that period.
That dipole develops around the 4th this run and is initially too far south- suppresses the potential wave for that timeframe. Like where this is heading though.
As the pattern progresses/gets colder these aren't the typical kind of GLs lows that will kill our thermals. There is going to be a lot of NS vorticity in the flow between the western ridge and the TPV. They can be either constructive or destructive to our hopes and dreams. Timing will be key.
Better interaction/a bit of phasing leads to a more robust shortwave for the 4th, pops a coastal low and we get a bit of snow. This could trend better going forward.
