Numerous local stations set a new monthly maximum temperature for the entire month of November or tied the old max yesterday. This is our first new monthly max since the mid 90s in October 2019. Luckily this wasn’t during July since there would have been widespread 100s.

Need to get the old winter regimes back. 

Maybe when the PDO and AMO flip? Thinking our best chances may be the back end of this decade, especially if the PDO begins to flip in the next two years or so as I’ve seen some suggestion of. No way of knowing yet though, of course. 

I think we need to see that intense marine heatwave off Japan calm down first. 

In hindsight I’m trying to stay positive that I’ve been relatively lucky so far this decade given how abysmal things have been. Eked out more snow than Boston last year, had an epic storm in 2022 here, and 2021 was pretty great even if not the best down at my house.

48 / 35 off a low of 41 and a previous high of 82.  Cooler 3 days  (Sat - Mon) 60s today, cooler Sunday, back to 60s monday.  Tue - Thu warmer near / low 80s (Tue and Wed) a touch cooler Thu with low 70s.  Cooler by the 8th/9th before warming the 11th.  Overall warmer than normal (some strong positives and near normal splits) with dry continuing.

My Winter Outlook
 

Here is my winter guess/forecast. Not going into huge detail to bore everyone but here goes. This is for Dec-Mar:

Oscillations (average) Dec-Mar: 

NAO: Positive

AO: Positive

PNA: Negative/RNA

EPO: Positive

WPO: Neutral

PDO: Strongly negative

AMO: Positive, w/continued New Foundland warm pool

IOD: Negative, has taken on a decided negative signature the past month

ENSO: (ONI) Central-based Weak La Niña/cold-neutral; RONI and MEI will likely be lower

QBO: Strongly positive

Solar: Very High, continued high number of sunspots, radio flux and geomag activity

MJO/Tropical Forcing: Favoring phases 4-6, Eastern Indian Ocean and Maritime Continent forcing. Very strong standing wave/OLR/-VP in that area the entire month of October, pattern feedback loop

Temps Dec-Mar average (NYC metro area):

+2 - +4

Snowfall Dec-Mar average (NYC metro area): 

Below normal; *Hardest to predict given that one storm could skew the entire season*

Main analog: 2001-2002

Reasoning:

Record drought/low soil moisture, pattern persistence since August 20th. Very dry falls correspond to below normal winter snowfall. I believe this continues throughout November. Actually is a way better correlation than fall temps

PDO/EPO: Is and has been record negative (-3), Persistent GOA/Bering Sea cold pools favor +EPO

PNA: -ENSO, -IOD; favors Indian Ocean and Maritime Continent forcing (MJO 4-6)

NAO/AO: High solar; high geomag activity, high sunspots, +QBO, -ENSO, +AMO w/New Foundland warm pool. AO: SPV projected to get very strong and very cold this month, fits with the above (solar, QBO, ENSO relationship). As far as the “SAI”, which I don’t follow for its very glaring failures in the past, but for those who do, Siberian snowcover buildup completely fell apart the last 2 weeks of October and is now perfectly normal. Not saying it’s completely irrelevant, but I don’t buy into it

WPO: Marine heatwave east of Japan strongly favoring an Aleutian High/ridge regime, which I believe will be a flat ridge as opposed to a poleward one the majority of the time

AMO: After briefly taking on a negative look late this summer, has gone right back to a positive signature. Atlantic SST profile has completely lacked any semblance of a “tripole” at any point since June; favors +NAO and beefed up SE ridge/WAR this winter, as does tropical forcing

QBO: Already eclipsed +12 in September, anomalies showing continued strengthening in October. Strongest on record (30mb) is +15, we may approach or even surpass that record when it peaks this winter; thinking the peak comes Dec/Jan

Arctic Sea Ice: Record low. I believe this will potentiate the +AO, +NAO. A recent study (2021) found that low arctic sea ice in combination with +QBO (especially in a Niña) results in a strong SPV/+AO

Volcanism: Cumulative VEI 5 eruptions of tropical volcano Ruang, which reached the stratosphere back in April. Although this will clearly NOT have the effect of a Pinatubo, it *may* possibly help to magnify the other factors mentioned influencing the AO/NAM

Atlantic ACE: Although ACE picked up to normal in October after being much below normal, it is still well below the 200+ number which has shown some correlation to the NAO in the past. So really no big signal either way on that. A non factor this time around

Good luck to everyone else with your winter outlooks

Historical:

 

1743: Benjamin Franklin's "eclipse hurricane" unlocked the key to storm movement. A rainstorm prevented Ben Franklin from viewing a lunar eclipse in Philadelphia, Pennsylvania, but his brother in Boston saw it, though the rain began an hour later. 

1946: A tornado hit Washington in Hempstead County in Arkansas, killing one.

1946 - A heavy wet snow began to cover the Southern Rockies. Up to three feet of snow blanketed the mountains of New Mexico, and a 31 inch snow at Denver CO caused roofs to collapse. (David Ludlum)

1961 - The temperature at Atlanta, GA, reached 84 degrees to establish a record for November. (The Weather Channel)

1966 - A storm brought 18 inches of snow to Celia KY in 24 hours. It tied the state 24 hour snowfall record first established at Bowling Green. (The Weather Channel)

1987 - A dozen cities, mostly in the Ohio Valley, reported record high temperatures for the date. Record highs included 83 degrees at Paducah KY and 84 degrees at Memphis TN. Temperatures reached 70 degrees as far north as southern Lower Michigan. Showers and thundershowers over southern Florida, associated with a tropical depression, produced 4.77 inches of rain at Tavernier, located in the Upper Florida Keys. (The National Weather Summary) (Storm Data)

1988 - A very intense low pressure system brought heavy rain, snow, and high winds, to parts of the northeastern U.S. Portland ME established a record for November with 4.52 inches of rain in 24 hours, and winds along the coast of Maine gusted to 74 mph at Southwest Harbor. Heavy snow blanketed parts of northern Vermont and upstate New York, with 15 inches reported at Spruce Hill NY. (The National Weather Summary) (Storm Data)

1989 - Squalls in the Upper Great Lakes Region the first three days of the month buried Ironwood MI under 46 inches of snow, and produced 40 inches at Hurley WI. Arctic cold invaded the Southern Plains Region. Midland TX reported a record low of 22 degrees. (The National Weather Summary) (Storm Data)

1992: Another infamous November Great Lakes Storm brought windy conditions to Minnesota's Lake Superior shoreline. 70 mph winds caused waves to crash over 130-foot walls along the shore.

That has to flip. Maybe it will eventually, nothing stays permanent. Hell we thought the Pacific heat ridge near Alaska/West Coast would stick in the 2010s. 

Yeah, so much for the Cali perma drought that was talked about ad nauseam on this site.

The -pdo for years now has really hurt us 

It’s gone way beyond the -PDO. That’s why we never saw this type of sustained warmth for 9 straight winters before. This recent paper discusses the historic rise in the SSTs from east of Japan to south of the Aleutians. Plus the subtropical Atlantic has warmed far beyond any past +AMO periods. 
 

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL101078

 

The fundamental result of this study is that the first EOF of SST in the North Pacific has changed starting in 2014. For more than 20 years, the PDO has been used to describe the state of the North Pacific. However, since the marine heatwave of 2014, there have been remarkable changes to the dominant mode of SST in the North Pacific. The spatial pattern of the first EOF of SST from 1950 to 2021 is notably different from the PDO, suggesting that though the PDO served as a useful metric of SST variations until 2014 (Johnstone & Mantua, 2014), it may no longer be as effective a climate index for the North Pacific. From 1950 until the 2014 MHW, the first EOF remained consistent in its proportion of positive and negative regions with both taking up roughly half the area of the North Pacific (and with the positive region taken to be the eastern Pacific). When EOFs are calculated from 1950 to endpoints after 2014, the first EOF has a maximum positive region covering 77% of the North Pacific, with a PC indicating the largest anomalies on record. These changes to the first EOF/PC of North Pacific SST are nothing short of remarkable.

In concert with these changes, the second EOF/PC of SST has also undergone profound evolution since 2014. This second EOF now accounts for approximately 18% of the variability, growing from 13% during the 1950–2013 period. The spatial structure of the second EOF now is positive over almost the entire basin, with a PC that has grown strongly positive in the last several years. Thus, the second EOF/PC describes warming over much of the Pacific not in the positive lobe of the first EOF.

I whipped up a little forecast myself. Came up with 20 inches swag guess on snow and +1.9 on temps, figuring a weak nina will give us a coupla shots at snow we haven’t seen in awhile. This is for central pork. And yeah I said pork. Mostly porked for the foreseeable future

There may be a brief, transient period with the tropical forcing? But overall? No

You skew warm though. So I have to view your forecast through that lens.

I dont necessarily disagree with your forecast, but it is important to mention you are the first to yell torch often to exaggeration   

 

Just like MJO skews cold. You get to know the posters on here.

A cooler air mass covers the region. Tomorrow will see highs top out in the middle 50s. Lows in New York City will be in the lower 40s with 30s outside the City. Frost is likely outside New York City, as well.

Afterward, a warming trend will commence. Tuesday and Wednesday could be very warm days with some locations challenging or breaking records on Wednesday.

Today is Philadelphia's 35th consecutive day with no measurable precipitation. The old record of 29 days was set during October 11 through November 8, 1874. Wilmington, DE has also gone 35 consecutive days without measurable precipitation. The old record of 34 days was set during January 7 through February 9, 1909.

The NAO fell to a preliminary -2.751 on September 24th (all-time September record: -2.371, September 12, 1971). That was the 9th lowest value on record. La Niña winters following September cases where the NAO fell to -1.900 or below featured a predominantly positive NAO. The most recent such winters were 2016-2017 and 2022-2023. The mean temperatures for those winters in New York City were 39.3° and 41.0° respectively. The 1991-2020 normal value is 36.2°. A warmer outcome is favored by the October run of the C3S multi-model forecast for Winter 2024-2025.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was -0.5°C for the week centered around October 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.30°C and the ENSO Region 3.4 anomaly has averaged -0.38°C. Neutral ENSO conditions will likely evolve into a La Niña event during the late fall.

The SOI was -9.93 today.

The preliminary Arctic Oscillation (AO) was +0.449 today.

While he may skew warm, and MJO cold, you just skew miserable

 

 

 

 

we haven't had a cold winter in a decade

It's like people on this board forget that AGW is 100% real and ramping up, kinda funny tbh.

If anything, I think the risk is that my forecast of +2 - + 4 this winter busts too cold given the rapid acceleration of AGW over the last 10 years
