Yeah, I just saw the new Euro monthlies. Another winter with a wall of -EPO/+PNA blocking. The Euro monthlies highest skill scores are with the EPO/PNA. But for some reason, the skill scores are lower on the Atlantic side with the NAO/AO phases. 

Isn't the NAO/AO much harder to predict?

 

this is from OSU:

This is another paper about NAO prediction.

Most important factors they found were fall Barents/Kara Sea Ice, fall wave 1 stratospheric disturbances and fall north Atlantic SST configuration.

Good question. It looks like the middle portion of November will be cold. These November -EPO cold shots since 2013 featured the first freeze and trace of snow for NYC.

Yes I see talk of mid November snow in a few subforums lol.  The question is will it just be a trace or might we see something more alone the lines of November 2012?

No frost here in SW Nassau and the lowest we got to so far was 38.

I should have clarified that I was talking about SE Nassau. Although there isn’t too much of a diffence in density between the two your proximity to the city heat island definitely keeps you a few degrees warmer on radiational cooling nights.

Yes you guys are lucky I look at Farmingdale temps and they are always around 5 degrees colder than us.  Sometimes we have the rare radiational cooling night (usually with snowcover) where we are up to 10 degrees colder than JFK and more in line with Farmingdale temps.  That kind of night (minus the snowcover) actually happened in late October 2016 when we were in the upper 20s here.

Surprised at the lack of any flood watches given the highly saturated ground and high local rivers and streams. 

Especially with what East Pennsylvania got the past few days. Hopefully this squall line will be moving at a good clip and we get less than an inch
