The teleconnections are posted above....
Generally speaking the NAO is forecasted around the time period to be pretty negative and then approaching off the charts negative.
The PNA is expected to be neutral to slightly positive...
The EPO is expected to be positive and significantly positive by the end of the period...However..at this time frame in question it looks to be more neutral...
Generally a Positive EPO would mean warmer air across the east coast. However..as one sees the NAO is off the charts negative and this is one cold signal. When you couple the NAO with a rising PNA and rising into the slightly positive category then you are arguing for more amplification despite the positive EPO.....
So not much, if anything has changed on the teleconnections. If anything a stronger NAO forecasted. So these connections are going to tell the tale of what happens with this next storm on or around the 3-4th of January....
