Yeah, looks like our typical post 2010 fall around the region. Endless summer into September or October followed by colder departures in November. This has become very predictable.

Yup. I believe last November we had a cold outbreak around the 20th then it warmed up just in time for Thanksgiving

November has been the only fall month with record lows around NYC since the super El Niño. But 17-18 was a much better winter into March than 19-20.

2017 was a sign of things to come as that late December into early Jan 2018 was brutally cold…

 

Probably the last true Pna -epo combo that favored cold in the east

Yeah, 2017 was one of the few Decembers since 2011 that was cold in the Northeast.

 

The one common denominator with Decembers in the Northeast since 2011 has been warmth regardless of El Niño or La Niña.

So we are due for a cold one I guess.

Just want to note that, and I think you guys are pretty much aware of it, the eruption (should it occur) in Iceland will not be anything that carries potential climate impacts. It could be intense and very damaging to the local population, but it will be a predominantly effusive fissure eruption as is typical over there. Now if Katla or Öræfajökull especially were waking up… different story. 

I’ve seen a few comments asking about the potential eruption in other threads here. But yeah, big danger to the population of Grindavík, zero intrigue as far as climate. 

You really need the absolutely massive and thus extremely rare fissure eruptions that have explosive components and the ability to get SO2 into the stratosphere (Laki, Eldgjá etc) to see climate impacts off these mainly effusive events. But this won’t be that, and they are extremely rare (only 3 known in the Holocene).

After a frosty start, readings should become slightly milder tomorrow. The warmup will likely peak Thursday and Friday. Dry conditions could continue until late in the week before showers or periods of rain could move into the region Friday night into Saturday.

The ENSO Region 1+2 anomaly was +2.2°C and the Region 3.4 anomaly was +1.8°C for the week centered around November 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.37°C and the ENSO Region 3.4 anomaly has averaged +1.63°C. El Niño conditions will likely continue to strengthen into the early winter with the current East-based event transitioning to a basinwide El Niño. That transition continues.

Currently, 2023 is in uncharted territory as far as the ENSO Region 3.4 anomaly and PDO are concerned. The October ENSO Region 3.4 anomaly was +1.59°C while the PDO was -1.71. Prior to 2023, the lowest October PDO when the ENSO Region 3.4 anomaly was +1.00°C or above was -0.36 in 1965.

The SOI was -21.13 today.

The preliminary Arctic Oscillation (AO) was +1.462 today.

On November 13 the MJO was in Phase 6 at an amplitude of 1628 (RMM). The November 12-adjusted amplitude was 1.739 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 70% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 46.9° (1.3° below normal).

He has a long personal history here. The old saying you reap what you sow applies.

 

Back to weather,  cooler this morning in metro area than in BTV. Interesting!
