ICON fell off this run.  0z starting of fine.  Knew it was gonna be different with how that sw in the south west held together

Everytime we are at a 50 50 crossroad it ends up being 100 percent fail

The PV will control that spacing. The models want to send in south. If that happens we are in the game. If it doesnt we are done. That is the bottom line. 

There are multiple players. It's always complicated with NS dominance, which prevails in a Nina. The energy riding overtop the western ridge is a separate issue from the TPV lobe. We need more spacing between that western energy and the lead digging shortwave AND we need the TPV to be in a position where it doesnt crush the digging shortwave, yet provides enough confluence to the north to keep a developing surface low tracking to our south...but not too far south. You get the picture.. its never easy unless we have a Modoki Nino with NA blocking. Then its just a come to papa waiting game with shortwaves in the southern stream.

12z ICON tracked the northern stream shortwave through Wyoming and phased in the ULL early. The 0z is much further east and misses the phase with the ULL. No Gulf low as a result. Also a more positively tilted trof and an Atlantic SLP along the offshore baroclinicity like other guidance. The 12z seemed unlikely since it had no support. But it showed the type of evolution that gives us our best shot at getting a significant coastal snowstorm.

Much more elegant than my analysis. But I do absolutely agree. :)

You gotta start looking at this like a slot machine man. We win some. We lose a lot more. But when we hit....

We don’t win anything man. Weather… sports? When is the last time you got double digits
