Teleconnector Update as of January 4th



Teleconnectors continue to indicate a very negative NAO of about -2.8 SD. They also continue to keep the NAO negative till the end of the period when it goes neutral and stays neutral.
PNA is negative as of last night but slowly trending to neutral and then expected to go positive and stay positive .
Meanwhile the EPO which is positive is expected to fall to neutral territory and then stay there....

All and all these signals continue to support a cold pattern across the east and northeast in the medium and long term. As we start to lose the NAO to neutral the EPO at neutral and a positive PNA will still be a cold signal for the east and northeast much like late November into Mid December.
