 Possibly heading into a rare 3rd year La Niña? 

It’s possible with this persistent La Niña background state since 16-17. Very hard for El Niño’s to get going and couple with the record SSTs near the Maritime Continent. These impressive MJO events  just keep reinforcing the La Niña. 
 

Nice discussion from the CPC:

 

• The MJO has shown better signs of organization, which is reflected in the observational RMM index and upper-level velocity potential anomalies depicting the leading edge of the main convective envelope shifting eastward over Africa and the western Indian Ocean during the past week.
• There is good agreement in the dynamical models favoring continued eastward propagation of the MJO across the Indian Ocean and into the Maritime Continent during the next two weeks. Several ensemble members suggest the possible development of a high amplitude event.
• The enhanced phase of the MJO, as well as predicted Kelvin and Rossby wave activity, is expected to increase chances for tropical cyclone formation mainly over the Indian Ocean during the next two weeks.
• The potential for the MJO to constructively interfere with the low frequency footprint would favor an extratropical response typical of La Niña, yielding warmer than normal temperatures across eastern North America later in March.

The record -PDO/-PMM state is very telling

A sustained warmer than normal pattern that could last for at least 1-2 weeks has now developed. Tomorrow will likely feature widespread high temperatures in the 60s.

There remains some potential for the month to end with cooler but not necessarily cold readings, but uncertainty that far out is high.

The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was -1.0°C for the week centered around March 9. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.22°C and the ENSO Region 3.4 anomaly has averaged -0.80°C. La Niña conditions will likely persist through March.

The SOI was +12.83 today.

The preliminary Arctic Oscillation (AO) was +1.156 today.

On March 12 the MJO was in Phase 1 at an amplitude of 1.836 (RMM). The March 11-adjusted amplitude was 1.697 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 88% probability that New York City will have a warmer than normal March (1991-2020 normal). March will likely finish with a mean temperature near 45.8° (3.0° above normal).

It’s over Johnny, done, finished, stick a fork in it, give it up, fat lady has sung, let it go, game over, bring down the curtain, lights out, say goodnight and goodbye, adios….a former winter. We don’t live at northern New England’s latitude….

Well this time I’m not sure I can argue. It really may be over until at least November.. can’t rule out a few colder days though.

I made that same call Presidents week. with little variation here and there, it was a good call :)

Morning thoughts…

It will be partly sunny and warm. High temperatures will likely reach the lower and middle 60s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 62°

Newark: 65°

Philadelphia: 68°

A general warmer than normal pattern will continue through at least the remainder of the week.

Normals:

New York City: 30-Year: 49.3°; 15-Year: 50.0°

Newark: 30-Year: 50.4°; 15-Year: 51.3°

Philadelphia: 30-Year: 52.3°; 15-Year: 52.8°

The next 8 days are averaging 53degs.(45/62) or +11.

Month to date is 41.9[+1.5].        Should be 46.0[+5.0] by the 23rd.

Reached 50 here yesterday.

Today: 58-61, wind sw., few clouds, 48 by tomorrow AM.

43*(65%RH) here at 7am.       50* at 11am.       54* at Noon.      55* at 12:30pm but has fallen back to just 51* at 2pm.       59* at 10pm.

The December 2015 extreme +13.3 departure marked the shift to much warmer winters. This is the first 7 year run of above average winter temperatures in our area.  The SE Ridge has never been this strong for such an extended period of time.

how many years does this have to be continue for the SE ridge to be considered a permanent feature in our climate?  at this rate, (and sooner rather than later) it looks like direct human climate modification is the only real solution to avoiding a climate catastrophe....one can argue the catastrophe has already begun but most humans haven't realized it yet.

They already have acknowledged that it has been increasing and the NE Coast is one of the fastest warming areas of the planet. But the climate models aren’t good enough to show it. So they are looking for theories like AMOC slow down and more +NAO. But we have seen the feature with a -AO like last winter with the south based blocking. 
 

https://www.nature.com/articles/s41558-021-01159-7

The northeastern United States (NEUS) and the adjacent Northwest Atlantic Shelf (NWS) have emerged as warming hotspots, but the connection between them remains unexplored. Here we use gridded observational and reanalysis datasets to show that the twentieth-century surface air temperature increase along the coastal NEUS is exceptional on the continental and hemispheric scale and is induced by a combination of two factors: the sea surface temperature (SST) increase in the NWS associated with a weakening Atlantic Meridional Overturning Circulation (AMOC), and atmospheric circulation changes associated with a more persistent positive North Atlantic Oscillation. These connections are important because AMOC slowdown and NWS warming are projected to continue. A survey of climate model simulations indicates that realistic SST representation at high spatial resolution might be a minimum requirement to capture the observed pattern of coastal warming, suggesting that prior projection-based assessments may not have captured key features in this populous region.

The interesting aspect of this is two fold, will it

a) increase the rate of icemelt of the Greenland Ice Shelf and 

b) will it accelerate sea level rise even more than what's currently projected to occur by 2050 and 2100?

Good morning S19. Judging from the number of weeny comments your Eulogy for the cold season garnered …. Anthony’s # 1 Weeny Power Ranking may be in jeopardy. Stay well, as always ….

Very alarming that entire swaths of winter now get cancelled out with extended +10 type weather.

 

It is the end of March, so no one cares…but a warm month is about to get a whole lot warmer

 

 

December was a torch, January was actually cold, Feb was warm and March looks like a torch.  Another 3-4 week winter lol.

They get into all those questions with the online presentation that was just posted a few weeks ago. Things like the increasing summer dewpoints in recent years. Why did the lower resolution  global climate models miss this. How some higher resolution models are doing a better job but are not perfect. Future areas of research to include increasing heavy snowfall and rainfall.

We have been noticing these changes.  It’s also interesting how many  of the storms correct further north in time. Plus week 2 model forecast cool downs that trend less impressive the closer in time the models get.

With 7 warm winters  in a row, seasonal forecasts need to include this new data. There  have been plenty of outlets that have been too cold with nearly all their winter forecasts since 15-16. So they owe it to their clients to absorb the presentation and correct their seasonal forecasts so their clients  can make better decisions.

January was 3.5 below normal and Feb was only 1.5 above. The heart of winter wasn't exactly a heat wave.

Another day with high temperatures beating  guidance. 65° now at Newark. So Newark moves into 4th place for most 65° days by March 15th.
