From the GFS ensembles this morning, the NAO is looking to drop (by average) to neutral in the LR (better). The AO is looking to drop to strongly negative in the LR (good). But, the PNA is looking to drop to near neutral / slightly positive in the LR (not as good).EPS has some members that absolutely send the EPO through the floor. As it stands now, the mean is at -3.
From my limited understanding, we'll need a -EPO to counter the loss of the +PNA. And maybe with a negative AO we can get some cold from Siberia into the mix. Lots of moving parts.... ..and do we even believe anything that's being spit out right now...
