donsutherland1 Posted 3 hours ago Share Posted 3 hours ago 1 hour ago, bluewave said: Yeah, the deeper consolidated low storm track just east of the APPS was responsible for a significant portion of their heaviest snowstorms and seasons. This storm track has pretty much been missing for the last 20 years. These days the primary lows tend to track to Cleveland or Buffalo with a weaker secondary going to their east. So they get both dry slots and warmth cutting down their snowfall totals. This is one of the reasons that I have been paying attention to the storm tracks responsible for our seasonal snowfall here. All of our seasons like this one with the coastal areas from EWR to ISP reach 25”+ since the 1990s have featured at least one benchmark NESIS snowstorm with a wide coverage of 10”+ amounts in the Northeast sometimes extending down into the Mid-Atlantic. Numerous seasons since 2018-2019 have been missing this storm track so most of the recent years have featured below average snowfall. Much of the time has featured the cutter, hugger, and suppressed Southern Stream storm track. Sometimes we get a hugger gradient in the I-78 to I-84 corridor leading to mixing even with the storm to our south. Following the late January benchmark snowstorm, we have reverted back to this common storm track pattern. So we only had one week this season with a dominant Southern Stream capable of producing a widespread 10”+ event near the coast. My question going forward is can we keep some semblance of this benchmark track active at times for the remainder of the 2020s so we can have more seasons at least approaching average? We had a discussion several months back about 50”+ snowfall seasons at EWR, NYC, LGA, and JFK. I expressed concern that it would be a challenge reaching this level due to how Northern stream dominant our storm tracks have become in addition to how warm the winters have become. Since a prerequisite for these 50”+ seasons especially during La Ninas and also El Ninos has been a winter with an average temperature near 32.0°. Well we finally got our first cold winter in over a decade. But the Southern stream was only able to become dominant for a week before the Northern Stream started dominating again. Most of the seasons since the 1990s as cold as this one featured 50”+ like 14-15, 13-14, 10-11 and 09-10. But those seasons allowed the Southern Stream to dominate long enough for widespread 50”+ snows around NYC. My guess is that the 2025-2026 winter could possibly be the only one this coldest for the remainder of the 2020s since cold bas been so scarce since 2015-2016. So its still uncertain whether we can get a near 32° winter to line up with a more relaxed Northern Stream for a 50”+ season. Since these two features have been necessary. Past 8 year stretches with snowfall this low like the late 1980s into early 1990s ended with 1993-1994 going 50”+ and 1995-1996 getting 75”+. So the remainder of the 2020s will be an important to see what the snowfall averages will look like heading into the 2030s. You raise important questions. The shift in the predominant storm tracks that you observed may be the result of an ongoing structural shift in storm tracks rather than periodic cycles. Many factors are involved, including cyclical ones, but there is at least some evidence that Arctic amplification is contributing. https://journals.ametsoc.org/view/journals/clim/30/10/jcli-d-16-0650.1.xml I still suspect that by the mid-2030s, we'll have a lot more answers related to regional snowfall, etc. 3 Link to comment Share on other sites More sharing options...

I have been actively comparing 2020 onwards to 1970 through 1999 and until now we are actually ahead of 1970 through 1976 for snowfall and above average snowfall winters. Also that period had 4 above average snowfall winters in 30 years, which was pretty bad living through it like I did (80s onwards). I distinctly remember the patterns were cold dry/warm wet for the majority of the winters (outside of the furnaces of the late 80s/early and lat 90s and the cold and dry early and mid 80s). So far outside of 2020/2021 we have seen either the furnace or cold and dry with the same overall storm track of the 1970 through 1990s. The similarities between 1955 and 1969 and 2000 through 2018 are also incredible. So like you stated, given that the last snowfall drought was a whopping 30 years we will need to wait until the mid 1930s to see if we have fared worse that that period. I would also like to leave the door open for INCREASED snowfall if the waters around the MJO phase 8 region also warm and allow for better storm tracks/increased warmth leading to larger snowstorms and less suppression. Some positive observations are: Still getting snow to the gulf Still getting benchmark storm tracks Still getting late season snow (May a couple of years ago) Still getting multiple below average temperature winter months The return of the clipper. The return of non-se ridge linking NAOs The hindrance of continuous phass 3 through 6 due to warm water pac waters The recent negatives are lower benchmark tracks and general increased global temps. Will be interesting to say the least. 3 Link to comment Share on other sites More sharing options...

I think there's a conspiracy among Big Model to pop something interesting each time the immediate threat dissipates, just for the purpose of keeping the viewership high on the NWS, AccuWeather, TWC, and, yes, americanwx sites. Yeah that's right, I went there. Link to comment Share on other sites More sharing options...
