The Nuri ET may be one of the strongest on record for so far north in the NPAC. It should

really help to pump the ridge over WNAM and drive the PV south into Canada next week.

The details will determine if the trough can dig enough into the GL for the first freeze

of the season in NYC.

The Euro has Nuri pressure down to 916mb at 102hr. Not far the non-tropical low pressure record 913mb, for the Northern Hemisphere or entire earth:

A lot of promising stuff going forward. I did notice the AO/NAO forecasts a bit more negative also especially the AO. The NAO actually looks quite variable jumping from more positive to somewhat negative, which may be representative of the stormy pattern we'll be seeing. 

 

Everyone needs to be patient though when it comes to these OP runs because they will shift from day to day. The big picture is more important than every OP run and the trends are in our favor overall. Case in point the forecast above is a great way to start December when snow threats actually become legit. Next week still looks like we'll be seeing some strong cold shots get involved and potentially a couple of interesting systems as well. 

 

The cold has still been quite scarce and I've yet to hit freezing but that may change next week.

Looks like the gfs is showing a more pronounced coastal storm early next week or end of the weekend.

 

The upgraded GFS doesnt have this feature. I think people should start referencing it, as it will be the operational GFS in a few weeks.

The "upgraded" GFS had this past weekends noreaster well east of the area for the 2 runs (6z and 0z) right before the storm.

It obviously needs a tweak or 2. That's why it's still experimental.

Im sure if the solutions were flipped Someone would be saying how the old GFS stinks and how they cant wait for the upgrade to become operational....

Enjoy it because it will be gone really quick

It does look like today and tomorrow will be the last time it'll be that warm in a long time. It certainly won't turn frigid right away but things look to turn below normal by late this week and then perhaps way below next week.

The real chill looks to be timed well with the AO dropping and also the typhoon recurving effects will if anything enhance the east coast troughing further.

Within a week we should be in a deep trough, since the rule generally is 7-10 days after a typhoon recurve.

Check out the blocking over the top on day 10 thru 15 on the euro ensembles .

Looks like the vortex gets traps and as a piece splits away spokes just pinwheel thru
