Then ENS/Cfsv2 all agree ridging from the Aleutians will progress eastward into the Gulf of Alaska, sending the GOA low down the west coast. This energy will likely be the next big weather maker across the country (but still a way's out). Progression of the ridge is likely supported by the recent warming of the NE Pac warm pool as well as possible warming of Nino 3 and 3.4. Higher heights return to the Arctic circle (-AO) but heights over Alaska isn't that all that impressively high. This isn't the ideal set up for very cold air masses as we shift away from the heart of winter, but it does allow lower heights which allows colder air to make it's way after Feb 20th.
I was going to post analogs and data for spring but that may be more appropriate for the spring thread than this thread
