I'm surprised no one has mentioned the indices. The AO looks to fall through the floor through January. The nao looks to try to go negative as we get close to mid month which is a great trend.

You're right. The AO just freakin' TANKS. Almost approaching -6 on one of the ensembles. :thumbsup:
NAO not quite as impressive, but still looks neutral-negative. :yikes:
PNA...well...no lol. BUT we do have ONE lonely ensemble member that spikes the PNA into positive territory! :lol:
MJO just looks meh.

Still feeling really good about early Jan. for an decent overrunning event with the PV setting up over SE Canada and a -NAO building in.  If the PNA can nudge into neutral-positive territory, would allow for something more by giving the s/w some room to dig.

Just an observation :  the ridge on the west coast is way too far offshore.  That has the potential to throw a major wrench in what otherwise would be a very good pattern to get a score out of. 

The -NAO says hello and would keep many in the SE forum in the "game".  The ridge where it is would allow wsw flow for an overrunning event somewhere in the southeast.  It's a very good look. The biggest balancing act would be the strength of the SE ridge.  Too little and it's a dry flow.  Too much and it's more a rainy one vs. snowy.

Trof orientation would be incorrect for a big storm.  Looks like the path of least restiance for the cold would be to dump in the SW and Midwest. 

 

Jmo but the fact we have a model even in the ballpark is encouraging.  One other feature that is missing is a 50/50 low signal.  

 

Again JMO.

The line of heartbreak would be sharp in that scenario...that's the prob with overrunning

We can always agree to disagree.  I'm not looking for a big storm, but that doesn't mean a long duration overrunning event can't provide what most in the southeast would consider a BIG storm (3-6 inches).

The trough in the west is needed to turn the flow from the west southwest.  There is a 50/50, albeit displaced a bit west of its traditional position, courtesy of a piece of the PV.

Overrunning is a different beast if you have the blocking.  Its the only time you want -PNA to turn the flow like you said.  Too much turn though and it's curtains

This is true.  Only way it works is if the PV is displaced south to keep the cold air hanging around while the WSW flow moves up.  The sfc low itself is weak and doesn't have the room to deepen and turn north but it brings a broad swath of precip as it moves across the south.  It's been a long time since we've had a significant overrunning snow event.

Taking this model verbatim, the freezing line moves up from parts of upstate SC in hr 216 to around the NC/SC line at 240. So depending on the 2m temps, looks like parts of upstate SC sees a snow-to-mix/ice event. 

The cut off would be fierce north to south.  That is just massive CAD that won't be dislodged easily.  This is an NC special

It's always a day 10-12 storm that never seems to materialize or if it does it's never what first was there. Don't get excited to much untill it's day 1-2! 


it's the pattern which gets rolling late this week. who cares about specific threats. the pattern is what's important . let's be honest, there is still plenty of time for this pattern to go wrong and screw us all
