Don and/or bluewave can confirm exact details, but I believe 2023 will surprass previous contenders for warmest year at NYC (2012 and 2020 were close to being tied at 57.3 F), as long as it remains above 1991-2020 normal value. As latest projections are close to +3 anomaly for Dec, 2023 would average close to 57.5 or even 57.6. January set a pace and despite one or two cooler months like Nov, it will become new top of the heap.

18z GFS ends (on Jan 4 2024) with a setup that looks like the next 36h of its run would turn into a large east coast winter storm, about like it was doing ten days ago for Dec 26-27 (which has degraded into the double rainer scenario). The difference could be that a lot more cold air is in place for this fantasy output. A long slow slide into deep winter is what I would expect and Dec will not be repeated in Jan or early Feb. Later Feb, possibly back to torch, but after a reasonable stretch of winter.

Partial dry slot developing but southern energy will be pulled in across NYC and w LI this afternoon, expect another 0.50" to 0.75" rain with that, winds will also pick up again to SW 40-55 in exposed areas. Squall line in w/c Long Island appears headed for central CT and will be focus of svr trw developing later in parts of e/c NE.
Double centered for now but will consolidate into one low over period 15z to 21z.
-
I notice numerous reports of intense TRW activity over central Long Island (in NYC forum) and it appears to be racing north into CT, with an associated warm front also looking active, would expect widespread TRW soon in large portions of sNE.
Low developed twin centers but is now consolidating and southern energy off Delmarva will be pulled into primary during afternoon. Could be some extreme obs posted, "marginal" svr wx now posted could be more like enhanced.
-
Actually surprised this did not get a name (Vince), have seen less impressive storms named in season. Took four months to get a TS designation on Atlantic January storm, so maybe same lag with (eventual) Vince.
Can see basis for dispute over wind speeds, but given the nearly STS nature of almost - Vince, I would be very reluctant to downgrade wind speeds based on global model isobars alone. All day long there have been gusts over 65mph ahead of developing southern center (it is going twin-centered o/n). West of CT River and central LI, I can see a good argument for reducing wind gust forecasts, at least beyond 15z. East of that I would go with Kev's estimates or at least an average of Kev and 007. Gradient actually increases later in day for maine, New hampshire.
Would expect svr wx potential e CT, n RI and parts of se ma towards 18z, even slgt tor risk.
Given severe component, some location will gust to 80-100 mph but at airport wx stations? It will likely be some place without official measurements but verifiable based on wind damage.
-
60 kt gusts are now as far north as Diamond Shoals off Cape hatteras. (60 kt = 67-68 mph)
-
Double centered structure indicated on GFS would cut off stronger winds after a brief interval late overnite, winds would only continue to be an issue about KISP-east after briefly affecting all regions.
Reggie is (a) overdone or (b) will nearly double existing Dec records.

Frying Pan Shoals, off the coast near NC/SC border, recently reported 42 kts sustained gusting to 60 kts.
This probably should be STS Vince, it is definitely at strong tropical storm intensity at present time. Is it going by any name from TWC?
-
I will guess 2.5 to 3.0 in, risk of 3.5 in.

Twin-centered low, would expect s component to cut off strong winds in NYC and w LI after first part of event. Inland NJ will see prolonged period of less windy or even calm conditions due to two-part train of lows (if verified). Rain could be under-done, 1909 one-day record is definitely on table at moment, timing is good for almost all rain to be on one calendar day (mon Dec 18).

Almost-Vince rapidly developing in eastern Gulf. Note squall line feature in western Cuba, center is probably around 1005 mbs near 25N 85W. Will track across n FL and se GA, up coast just a bit inland at times, over DCA-BAL region late Sunday, n NJ by monday.

Link will probably update to current time as you encounter it, so comments above apply to 21z imagery.
Currently over 78-80 F SST region, so legit tropical storm candidate, "almost" Vince could be Vince (bookend un-named tropical storms for 2023? -- one in January).

Storm is about as close to being a tropical storm as a Dec east coast storm can be, I even think there is a chance of it being named (as a STS), but whether or not that happens, potential for one-day DEC rainfall record (3.09" at NYC) to be challenged. (2-d totals around 3.5" if arrival is overnight) ... Very windy on Long Island and southern New England, not so sure it will be windy inland NJ, possibly just along coast briefly. It's rather like blizzard of '93 without cold air available (for track and intensity).
Second event could be a figment of some models' imagination. It is way OTS on other guidance. A very good pattern is slowly developing by Dec 26, two possible winter storms but phasing with late-arriving cold air from Quebec rather than deep arctic air from central Canada, could be a negative for coast, would put money on heavy snowfalls in interior regions and perhaps mixing near coast with first of two (26-27), second one (29-30) looks more promising generally.

Season is probably done but maybe not, eastern Gulf storm looks almost tropical storm, and westward moving low in subtropics could be a stat padder (for me anyway).
-
If for any reason it cooled down on an epic scale (volcanic dust, solar downturns, unknown cause and effect) we would begin to be glad for AGW signal, it could save our society considerable stress. But nobody is predicting it would work out so. It would probably rain even greater values, be cloudy all day, and around 1961-90 averages. Sort of like a worst case scenario but not too cold to survive.

Yes, it was also a very cold winter in Britain, after a very warm year (1779) that provides warmest Feb even now after 2.5 centuries.
Sure you also know about extreme snowfalls in Feb-mar 1717.

Recall Binghamton NY getting 40" of snow at same time of year a few years ago.
It was Dec 17, 2020.
There was a thread started by wdrag about this storm on Dec 11, 2020 and it was a fairly widespread snowfall event as it turned out.
December 2023
