There’s a lot going on with the upcoming Northeast snowstorm and California rainstorm but when looking out into the 1-3 week period, boy have we not some exciting indicators starting to reveal themselves.
Latest snowfall forecast for the Northeast through 168 hours off ECMWF.
NWS in the Bay Area are geared up for a smacking mid week.

I happened to glance at the GFS 50mb temperatures through the next 240 hours and I’m seeing the model wildly displace the polar vortex away from the pole down into the North Atlantic and then across to the Eurasian border. That’s some wild movement and a potential sign of some big rumblings from up above. This may significant shape the period late December into early and mid-January as alluded to back at the end of November.
Check it out. This could suggest an SSWE.

Remember what the modelling has been showing now for quite sometime. Building heights further north and west over the continent.
Here’s the EPS control.
Sure we have a -AO and +PNA returning but have you noticed the trend with the NAO too?
I like what the CFSv2 has week 3 and 4 with the Alaska to Greenland block and trough over the Southeast.
The November stats are out and according to NOAA the month ended 2.4F below normal and 16th coldest.
The January through November 2014 period ends coldest since 1997.
While it was Alaska’s 7th warmest it was the 2nd coldest for both Alabama and Mississippi.
As for snow cover, it was the greatest coverage for November on record.
