It’s remarkable how that November 1995 pattern locked in right  through April. That was an example of a stuck weather pattern from before the 2010s era. It will be interesting to see how low we can extend that 6-10 day +EPO, SW ridge, and -NAO.

Ultimately it was not that cold of a winter though because that massive January thaw as well as 12/20-12/30 was somewhat warm too I think.  There was some belief that 95-96 was a product precip wise of that long duration El Nino from 1990-94 more or less and we had a lag which enabled there to be so much juice and storms despite the La Nina

I know we had a 2-3” snow event around NYC at the end of November 1995. But the highest impact storm that month was the November 11th powerful cutter. I had 70-75 mph SSW gusts with a severe squall line that came through near midnight. Quite a few power outages around the area after that severe event. 

 

That was the only storm that winter which got badly blown...when you consider you had the ETA which was 18 months in, the NGM the AVN and the Euro running once a day its amazing how well forecast most of the events that winter were.....the 12/19 event the mid level warm nose was missed for S LI but they still reached the expected amounts of 6-10 more or less.

Working up a cautious thread... very cautious. You may not like it but there is so much chatter about potential...  I am liking after Thanks giving overall better. Will try to briefly explain in thread. Should post by 715P. Few if any graphics, just not enough consensus to hang my hat on.

Stuck patterns have been the norm the past few years too.  Stuck model forecasting…not so much :-P.  So let’s see if we can get some run-to-run consistency on this.

Coincidentally, Vet’s Day 1995 featured a high-wind event.  So too did 11/13/21…. :whistle:

12/20-12/30 wasnt warm, we had snow from mid December (from the above storm) that stuck on the ground all the way to the January blizzard...as a matter of fact late December and early January was probably the most consistently cold that it was that winter.

3-6" inches on Long Island, I loved that storm

Why are you obsessed with JB?..he's just like you, except you hype warmth

he pops in all of a sudden during warm patterns and mysteriously disappears during cold patterns lol

and the most ironic thing is his handle is "snowman"

I wish a mod would change it to "rainman" like the guy in the movie ;-)

Morning thoughts…

Today will be partly to mostly sunny but still cool. High temperatures will likely reach the upper 40s and lower 50s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 48°

Newark: 52°

Philadelphia: 50°

Normals:

New York City: 30-Year: 53.9°; 15-Year: 53.9°

Newark: 30-Year: 54.7°; 15-Year: 54.9°

Philadelphia: 30-Year: 55.7°; 15-Year: 55.7°

Warmer air will arrive tomorrow.

I think you just repeated what I posted lol. I’m not debating that it won’t get cold/blocky next week. I'm just saying that going into December things might get hostile if blocking were to break down 

Dr. Paul Roundy, the premier expert on the MJO (developed the Roundy plots) agrees with your concerns. He is forecasting the AO/NAO blocking to only be temporary as the MJO forcing becomes hostile once we get into early December:

Warmer air will move back into the region tomorrow. Ahead of the next cold front, Thursday will see much above normal temperatures. Noticeably colder air will return on Friday. Another surge is possible early next week.

Overall, it is likely that the temperature anomaly for the second half of November will be somewhat below normal due to the development of AO blocking. The latest teleconnections forecasts suggest that the AO will drop sharply to somewhere between -3.000 and -1.000 on or after November 20. Such an outcome favors a period of colder than normal weather (November 20-30, 1991-2020 period):

Boston: Normal: 42.2°; AO cases: 38.4°
New York City: Normal: 45.5°; AO cases: 41.7°
Philadelphia: Normal: 45.4°; AO cases: 41.7°

Fall 2021 is well on course to being wetter to much wetter than normal in the northern Middle Atlantic region. Since 1869, there have been 9 August cases where New York City picked up 20.00" or more rainfall during the summer. Two thirds of those cases (and 4/5 of those with summer mean temperatures of 73.0° or above) had 17.00" or more fall precipitation in New York City. 2011 is probably the closest match in terms of precipitation and a nearly identical summer mean temperature. Mean fall precipitation for those 9 cases was 14.86". The median was 17.35". The 1991-2020 normal value is 12.27". Fall rainfall through November 16 4 pm is 16.13".

Following very wet July-September periods, winter (December-February) precipitation has typically been near or below normal. The most recent exception was winter 2018-19.

The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was -0.8°C for the week centered around November 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.53°C and the ENSO Region 3.4 anomaly has averaged -0.85°C. La Niña conditions will likely persist into at least late winter.

The SOI was +2.03 today.

The preliminary Arctic Oscillation (AO) figure was +0.928 today.

On November 14 the MJO was in Phase 5 at an amplitude of 1.388 (RMM). The November 13-adjusted amplitude was 1.189 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 66% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 47.4° (0.6° below normal).
