GFS ensembles show a storm in this period, it is late 15 days out, but the system in question impacts the flow across the US within three days time. The breakdown of the polar vortex over the Gulf of Alaska into two or three pieces of shortwave energy will determine our next major winter storm across the eastern US. Although this is in the extreme long range, there is enough model consensus within the GFS long range family of models to suggest that the PNA will soon become positive and the NAO/AO will become negative in this period. Individual ensemble members show a storm in this late period around hour 372 and beyond. THis could be a doozy of a storm for the Eastern US.
