Next 8 days averaging 44degs., or about 3degs. BN.

 

NYC now @-1.8degs. for the month and should be about -2degs. or better by the 21st.  No AN 8-day period is likely till Dec.  Dec. still way AN everywhere, save the Pacific NW.

 

Not discrediting your AN++ call for Dec as a few others have similar thinking but what pattern/teleconnections are you using to base this outlook on? Ie, -pna, +ao, relentless SE ridging, pac firehose, etc?

The "confused/confusing" CFS output which has the next 45 days BN, that is virtually all of Dec. you know, and its monthly 'Redout' which roasts everyone.  JB likes a BN Dec. and Nov. will be BN w/o being predicted so by Nov.01.  An accident or a new modality setting in after 31 months?

You have to be careful with these calls. A few weeks ago, they were well above normal for month of November. I believe the call was above normal until April. 

It is to be appreciated, but taken with a grain of salt.

I am and have been in the "early and often" start to the season since mid-Sept with a BN  temps Nov and Dec at the very least. The only wrench was when the pattern had briefly flipped with the record low SLP and Phillippe debacle back in Oct and I said uh oh my outlook is in jeopardy via the almost complete pattern reversal, but as we found out, that crap pattern had virtually zero holding power and we headed right back into similar teleconnections that we had seen since nearly mid-summer. That's not to say this upcoming west-based -NAO prog along with a pumped up SW ridge, neutral to positive PNA, and -AO outlook cant totally roll over on itself and torch us in December as some have alluded to. However, this pattern has holding power it seems thru at least the early part of winter and wants to seemingly hang around.

Looks like all the models now have a storm before Turkey Day

Right now, it looks warm for our area but we have to see if the models correct the storm to the south with the block in place.

The 00z Euro was much weaker, with barely a surface reflection.

This might do it: https://waterdata.usgs.gov/nwis/uv?cb_00010=on&cb_00060=on&cb_00095=on&cb_62619=on&cb_63680=on&cb_72137=on&format=html&site_no=01372058&period=&begin_date=2017-11-05&end_date=2017-11-12

Has a lot of other 'water quality' type stats too.   Reminds me that back during the early 1960's drought, the City was force to build [1964] a pumping station above the 'salt line'---beyond Kingston, I suppose ---(but not above the pollution line  lol) as our reservoirs headed toward 20% when 80%-90% was normal.  Chlorine up the wazzoo was added and the flow was fed directly into one of the water tunnels and on to our taps.   This has info on the plant which was at Chelsea, which is below Kingston.

It's why I attached a $300 water filter going into my main line.

Our most "ice-covered" winters I can think of are- 1976-77, 1977-78, 1978-79 (three in a row!), 1980-81, 1981-82, 1984-85, 1989-90, 1993-94, 2003-04, 2014-2015.  Funny to see 1989-90 in that list, but December 1989 was extremely cold (more than 10 degrees below normal for the month!)  Our coldest months in that period were January 1977, December 1989, January 1994, January 2004, February 2015.  I can't remember the last time we had a February month 10 degrees below normal (maybe February 1934?)

 

Notable Arctic shots that I've experienced:

January 1977- monthlong cold, peaked at (-2) in NYC

Christmas 1980- only below zero Xmas (-1) I remember at NYC.

January 1985- big inauguration day arctic shot (-2) at NYC

January 1994- first time in 50 years that NYC got to 0 or below from two separate arctic shots (and three lows of 0 or below- 0,-2, 0).

February 2016- first below zero temp at NYC (-1) in the month of February in over 70 years.

 

We still haven't had a low below -2 since the 1940s, when it happened multiple times, including a dip to (-6)!

December 1989 was amazing that every single day had a 32 degree or less reading

as did a lot of the 1960's Decembers 1959 had some mild days the first half of the month...then it would get cold in the second half with a snowstorm for Christmas...1995 was like those years...1959 is the warmest of these Decembers by three degrees on average over 1961 and eight degrees warmer than 1960...the best Decembers got their warmest days at the beginning of the month...

1959...55 on the 3rd...56 on the 16th...snowstorm 12/21-22...coldest air of the season...

1960...62 on the 5th...64 on the 6th......snowstorm 12/11-12...record cold...

1961...51 on the 4th...58 on the 5th......snowstorm 12/23-24...cold enough...

1962...68 on the 1st...53 on the 6th......snowstorm 12/21-22...very cold mid month...

1963...55 on the 8th.............................snowstorm 23-24th...very cold mid month...

1966...66 on the 9th...62 on the 10th.....snowstorm 24-25th...cold enough...

1969...54 on the 10th...60 on the 11th...snowstorm Christmas night...cold enough...

1970...66 on the 2nd...64 on the 3rd.....snow 12/22 with sleet...cold Christmas week...

1995...55 on the 3rd...52 on the 4th......snowstorm 12/19-20th...cold mid month...

 

Weren't 1966-67 and 1993-94 also like this?  Early December mild, late December snow and cold.

Select Record Low Temperatures for 11/12/2017:

New York City:
…JFK: 29° (old record: 32°)
Newark: 28° (old record: 29°)
White Plains: 25° (old record: 26°)
JFK and Newark set records on November 10, 11, and 12.

 

When was the last time either had three straight record lows? Wow.  Did Marthas Vineyard, Westhampton and Toms River all get down to 19 degrees Saturday Morning, Don?

The block was so strong all the heavy snows missed us to the south and we had 1-2" clippers but it was so cold that 1-2" of snow stuck to the ground all month!  I remember Philly had something like 34 straight days with a 32 degree reading or less.

Looks like area wide snow showers for Sunday as the trough comes through which will signal a colder pattern. The lake regions are going to get buried.

We also have to watch the thanksgiving week storm. It has a chance of coming in more south.

GFS was best run as of yet, trough still positive and a bit to fast, doesn’t allow it to develop just slides out off coast

Obviously too early for specifics, but are their signals for day before, day of, or day after? Asking regarding travel arrangements.

I’d say so, after the cutter departs heights look to rebuild, slowing this to dig further south, timing looks key, right now this is a tad too quick, the trough is barely neutral as it pushes past, slower allowing more of a neutral/neg tilt would allow us to tap the southern moisture, and funnel moisture into area... we want this trough west further at this timeframe
