The biggest benefitters have been those south of Buffalo including myself. We probably average 110" a year at my location. But here are my totals since keeping track down here. Averages out to 129.42" a year. I've had 2 75"+ events since 2022 and a once in a century blizzard with almost 60". The same cannot be said for other areas though. Rochester and Syracuse have had record low snowfall totals the last 6-7 yrs due to the lack of cold air and NW flow. All the flows have been WSW/SW with the cutter pattern we've had. 2013-14 snowfall: 161.7" 2018-19 snowfall: 122.8” 2023-24 snowfall: 125.1" 2014-15 snowfall: 212.8" 2019-20 snowfall: 83.3" 2015-16 snowfall: 80.1" 2020-21 snowfall: 101.1" 2016-17 snowfall: 93.3" 2021-22 snowfall: 105.4" 2017-18 snowfall: 152.4" 2022-23 snowfall: 185.6" 3 Link to comment Share on other sites More sharing options...

Another interesting thing to add...since the 15-16 super nino, while the winters have been mild, (and it was made even more annoying by the record snowy stretch that it just followed), we have set a slew of early and late season snow records/quirks: ~cold/snowy Novembers ~largest Nov snowstorm on record (Nov 11, 2019) ~most consecutive days in a row with May snow (5) May 8-12, 2020 ~3 consecutive years (2020, 2021, 2022) saw a snowstorm between April 17-21 drop 2-6" on the area ~snowiest Halloween on record (2023) That's just Detroit. You see the snowgasm south Buffalo has been enjoying. And there have been a few very impressive record arctic shots as well, showing the cold is there. The thing is, warming climate or not, the snow season is very long from 1st to last flake. And we all can use the added moisture to our benefit IF/WHEN the pattern works out. And this goes for you too. It's a different climate but don't think for one second that an absolutely massive moisture laden bomb can't bury NYC in feet of snow. Just a decade ago everyone was having snowy winter after snowy winter. That's not that long ago. There are many factors at play, including enso and changes in climate, but the overall hostile nature of the pattern, especially for the east coast, doesn't get nearly enough credit for whats happened in recent winters imo. If below zero temps and -30° to -40° wind chills can pop in for a visit during one of the warmest winters on record (see Jan 2024), the east coast can get a good snow season. Pattern just needs to shake up. 1 Link to comment Share on other sites More sharing options...

I'm sure global warming begets more warm, but that I have a +4F anomalies in some cases, with over 40% of the dataset being used is a pretty strong index-rolled forward signal. +EPO and +NAO are cold weather anomalies, so there is something of a balancing act to the referenced.

Barring something really weird happening in the next 3 weeks before November arrives, I think the main drivers for this winter are probably already set…..CP La Niña (weak), very strong -PDO, -PMM, -IOD (weak), +AMO/New Foundland warm pool, +QBO, solar max/high geomag, low arctic sea ice, MJO very likely favoring phases 4-6, AGW, near average Atlantic ACE?. The only question I have at this point is what effects if any and likely minor (does it potentiate the Niña/+QBO/high solar effect on the AO?), will the cumulative VEI 5 Ruang volcanic eruptions back in April have on the stratosphere.

Pattern just needs to shake up. We have two issues at work along the 1-95 corridor in the NYC Metro forecast zones. First, it was like someone flipped switch to warmer with the +13.3 December 2015. But we were still working with more of a favorable +PDO-like pattern into 17-18. The Benchmark storm track was still going strong since the 09-10 or even 02-03 winter with regular record snowfalls. But especially from 15-16 to 17-18 record warmth very close to our big snowfalls. We had blizzards when it was in the record 60s days before or after the snows. I got used to rapid snowmelts following the storms. So the snow cover days were declining relative to past colder and snowier seasons. We went from record warmth with 70s near Christmas in 2015 to one of our greatest snowstorms in January near 30” in NYC. Then a brief Arctic shot in February for the first below 0° since 1994. But a quick recovery back to the 60s following this. 16-17 was also one of our warmest winters but we managed some great snowstorms even if the 60s were close by. Then the 17-18 winter started with a great Arctic shot after Christmas and record 950 mb Benchmark blizzard in early January. But a quick reversal in mid-January and then record 80° warmth in February before record 30” inch snows in March. Much of this volatility was a combination of record MJO 4-7 activity interacting with the lingering +PDO. A great November snowstorm in 2018 before the Pacific began to shift. This takes us to the second factor which was how hostile the Pacific has become with a -PDO signature in this warming climate. 18-19 witnessed a rare El Niño failure due to the record WPAC warm pool which has been driving the warm MJO phases. So we went most of the winter with only a snow squall to show for the pattern while the Chicago area was seeing record cold in the -20s. Then we got into the turn of the new decade in 19-20 with a raging polar vortex and Pacific Jet with more warmth and well below normal snows. 20-21 was a nice reprieve but it was still warmer than average even with a great +PNA -AO. This would have been a much colder pattern in the past like 10-11 was with similar levels of blocking. But the block became too south based favoring places like BGM for the record 40” smowstorm before Christmas. But then the raging Pacific Jet returned on Christmas with the 40” snow pack melting rapidly and causing flash flooding and landslides at the ski resorts. 21-21 started with record warmth in December before seeing our last good winter month in January. The most recent stretch since February 2022 to this past winter was our warmest and least snowiest so close together with numerous locations setting records for stretches with under 4” and 2” snowstorms. We made it to a record 9 warmer winters in a row with some degree of Southeast Ridging. Now we are faced with another extreme global temperature jump even exceeding the 15-16 one. So I am waiting to see what this new even warmer baseline jump looks like in the coming years. So you see we were able to manage the warmth for great snowstorms before the Pacific shifted. But this hostile storm track plus the warmth has been a very challenging winter mix. When we did shift the MJO to 8 in January 2022 places like ACY were able to manage a record 30” month. But that was a fleeting pattern before the MJO went right back to 4-7. So even a short term favorable Pacific period can still produce to some extent. The question now becomes over the next few winters can we still manage a few of these favorable periods even with this new higher temperature baseline. I will remain open and take a wait and see approach. All these new marine heatwaves are really distorting how our past climate used to operate. 2 1 Link to comment Share on other sites More sharing options...

The key takeaway right now is that the Euro seasonal is warm, but not as warm as the last two winters. All things being equal, there should be some better opportunities for snowfall than one has seen in parts of the East during the past two winters. I still think the Great Lakes region will have normal to somewhat above normal snowfall. For those who are interested, February is forecast to be only slightly above normal in the Mid-Atlantic Region (southern Great Lakes Region) and near normal in New England (much of the Great Lakes Region). 1 Link to comment Share on other sites More sharing options...

But it’s going to be feast or famine (i.e., more extremes) and, as the decades pass, probably more famine than feast. Thanks for the kind words. I think we got used to the linear warming pattern from the 1970s into 2000s. While it was getting warmer the blocking was also increasing along with the atmospheric moisture. So when everything lined up we had the record snows even if it also had periods of record warmth. But the 15-16 super El Nino feels like it may have ushered in more of a non-linear shift. This has been leading to patterns getting stuck in place for much longer periods of time than we had been accustomed to in the past. Plus we just experienced and even stronger global temperature rise and new higher baseline. While the WPAC warm pool has been leading to more frequent La Ninas and MJO 4-7 patterns since 1980, we were able to get some more favorable +PDOs in the mix. The question now becomes does the configuration of SST warming favor more frequent and intense -PDOs than +PDOs along with +AMOs over -AMOs. I don’t think we have enough data yet to make that determination. But it may have to be something we have to address if this very hostile Pacific continues and the Atlantic SSTs keep increasing. But I agree with you that the increasing moisture is there for snow storms if we can switch back periodically to some elements of a 21-22 season or even 20-21 where the Pacific can briefly become more favorable.

Based on 850mb DJF climo, it gets down to around -3 along i-95. The past two winters were so warm that the 850s averaged 0 or above, which is a death sentence for snow prospects here. If it’s not going to be as warm, we could maybe have opportunities in borderline situations with west of 95 doing better. 1 Link to comment Share on other sites More sharing options...

I want to know why a Strong El Nino could lead to 9 years of strong -PNA. Maybe it's just a coincidence or the strong ENSO event is just a blip in an otherwise strong background state? Once the Pacific becomes more favorable, the higher precip tendency should give us some above average snowfall years, for sure.. Last season was very similar to 1972-1973 with the strong el Nini in the midst of a cold phase of the Pacific. 59 minutes ago, donsutherland1 said: When it gets closer to the season, I'll post month-by-month estimates (if I recall correctly, the skill related to the 3-month average is better than that for month-by-month forecasts from this timeframe). The key takeaway right now is that the Euro seasonal is warm, but not as warm as the last two winters. All things being equal, there should be some better opportunities for snowfall than one has seen in parts of the East during the past two winters. I still think the Great Lakes region will have normal to somewhat above normal snowfall. For those who are interested, February is forecast to be only slightly above normal in the Mid-Atlantic Region (southern Great Lakes Region) and near normal in New England (much of the Great Lakes Region). Agreed. Still warm, but better than last year. 2 Link to comment Share on other sites More sharing options...
