NEG NAO Posted yesterday at 03:09 PM Share Posted yesterday at 03:09 PM 1 minute ago, bluewave said: This La Niña progression was much more amplified due to the record early stratospheric disruption in late November. The wildcard going forward is now much influence the stratosphere has on the rest of the La Niña progression. All we know for sure is that the stratospheric influence couldn’t shift the persistent Northern Stream of the Pacific Jet. So the rarity of the 500mb pattern with the fast Pacific flow actually worked in our favor for once in December with the record two 4-8” clippers. But now that the stratospheric influence is fading, we are back to the Northern stream interfering with snowier outcomes like we saw with earlier forecasts for this week. I would like your opinion on what I mentioned earlier with so many snowy NYC Decembers 7 inches or more ending up with above normal seasonal snowfall and quite a few much above normal Febs. monthlyseasonalsnowfall.pdf Link to comment Share on other sites More sharing options...

They peak in November/December then start fading. Every event does it. It’s a perfectly normal progression. And what strat warming? There is no strat warming predicted right now, in fact the SPV is strengthening. This idea being floated around twitter that we are going to magically light switch flip the atmosphere into Modoki El Niño forcing by February is preposterous IMO. The premise that we are just going to go from following a front-loaded La Niña winter evolution to a tee from late November to the present, then just when the classic progression into a canonical February is supposed to happen, Modoki El Niño (cold/snowy) forcing is going to take over for February and March? That seems too unbelievable. You just don’t light switch flip the atmosphere from one completely different ENSO base state to another that quickly. There is always a lag before an atmospheric response. It defies physics and common sense IMO Every LA Nina fades at this time of the year ? What are you talking about ? In 2010-2011 , we had a La Nina that was strengthening as winter went on. 2 1 Link to comment Share on other sites More sharing options...

MANDA Posted yesterday at 03:16 PM Share Posted yesterday at 03:16 PM 2 hours ago, bluewave said: Looks like a very changeable pattern this month alternating between troughs and ridges in the East for the next few weeks. First week is starting out with a cold trough near our area.Then the ridge builds into the East this week for a thaw.This is followed again with a trough and colder around the 15th. Then another ridge and moderation as we approach the 20th. Honestly I'm looking forward to the upcoming thaw (I wouldn't call it a torch) but at the same time I am glad it is looking transient. Another very light dusting of snow this morning. Thankfully they did not come around and do another salt dump. These little snow events are ok but now that the holidays are past I can do without these nuisance events and the persistent cold and wind has become a bit much. I'll be ready do go again in about 10 days! In search of a KU this season but don't see the pattern for one showing up next two weeks at least. Based on the current medium to longer range guidance it looks the anomalies during colder periods would exceed those of the milder pauses in the transient pattern. 1 Link to comment Share on other sites More sharing options...

This is the first time since 1988 that ISP has 10”+ in December and either Philly or Boston doesn’t have at least 10” also. It’s why we may not be able to use the snowy December winter analogs that followed the other 10” December years on the list. This is due to the 10” at ISP being the first December with two 5”+ clippers that had narrower areas with heavy snow than benchmark coastal snowstorms that also affected Philly or Boston in the other snowy Decembers at Islip. So it will be interesting to see how the rest of the winter plays out at all three locations. All 10”+ snowy Decembers at ISP and the Boston and Philly snowfall 2009…ISP…25.3”….BOS….15.2”….PHI….24.1” 2002…ISP….16.0”….BOS….11.1”……PHI….8.4” 2003…ISP….15.5”…..BOS….21.5”….PHI….6.0” 2010….ISP….14.9”…..BOS…..22.0”…PHI…12.7” 1995….ISP…..13.3”…..BOS…..12.6”….PHI….7.3” 2025….ISP…12.4”…..BOS…..2.3”……PHI….4.5” 1969….ISP….12.0”…..BOS……12.6”….PHI….7.5” 1975…..ISP….11.4”…..BOS…..19.3”……PHI….7.5” 1963…..ISP…..11.0”….BOS….17.7”…….PHI….8.0” 2000….ISP…..10.8”….BOS….4.5”….…PHI…..10.5” 2008….ISP…..10.4”….BOS….25.3”…..PHI…..0.4” 1988…..ISP…..10.4”….BOS….3.7”……PHI…..0.4” The way we got our snowfall this past December was different from the previous cold and snowy Decembers. This was our first December since at least 1950 with two 4-8” snowfall clippers. Past snowy Decembers into early January had big KU systems with widespread snows over 10”. The models backing off the coastal system which was forecast for next week is telling us that the Northern Stream is still dominant. We haven’t had a widespread 25”+ season from EWR-NYC-LGA-JFK-ISP in over 30 years without at least one KU NESIS Cat 1 event or higher. The other thing is that all our recent winters since 21-22 had most of the seasonal snowfall focused into just one winter month. This is why I am concerned that absent a revival of the BM coastal storm track before this winter is over, that December will be our snowiest winter month this year and most spots from EWR to ISP finish with another below average snowfall season. Since it was something like a 50 year+ event to get two 4-8” snowfall clippers in a two week period in December. That really productive clipper pattern for snow has shifted and we still haven’t seen evidence for a big KU pattern developing. Whatever happens, this was our best December in terms of cold and snow in a long time which we are all very grateful for. 1 4 Link to comment Share on other sites More sharing options...
eduggs Posted yesterday at 03:32 PM Share Posted yesterday at 03:32 PM The GEFS have been shifting south for Friday night/Saturday (Jan 10). A few members take a surface low - possibly a secondary low - near or south of our region. A well timed shortwave in the northern stream might provide a just-suppressive enough flow to give us some wintry precipitation. It's kind of grasping at straws, but that's probably the next period to watch for a few runs even though this likely ends as some form of a cutter.

Mostly 50s We will have to almost completely rely on the northern stream for some sort of action because there is no evidence of a coastal storm pattern showing up yet. Maybe after the trough swings back east around the 11th. Very rare to make it to our seasonal snowfall without some sort of KU storm. But yeah from 1/6-1/10 it's looking quite warm. 50s next weekend!

If we're lucky, we'll get some sort of wintry precip at the start Pattern Change is a made up concept. Every day is a unique atmospheric circulation. Sure we can identify characteristics of atmospheric circulations in real time and quantify them to create numerical indexes. But these are coarse numerical "descriptions." And none of this is very meaningful when focusing on snowfall, which is a local phenomenon and highly dependent on specific regional weather features. The bigger problem is that we cannot accurately forecast these patterns beyond 10 days. So 15 day ensemble mean charts are not very useful at identifying or forecasting weather patterns. At this very moment we can have little confidence in what the "pattern" will look like beyond next week. Link to comment Share on other sites More sharing options...

So much for the warm pool keeping us in phases 4/5/6, clippers being extinct, NAO always linking to the SE Ridge, SE ridge being an entity in itself and taking over. I think you even showed the warm pool was shifting slowly east which would be favorable (i.e. the western warm pool being there "the rest of our lives"). I'm of the opinion that I do not believe we ever really truly achieved phase 8 on that first attempt. The signal was shoved there with a turbocharged (due to the events in the strat) CCKW. However that waned as the strat event ended. Plus the falling AAM at the same time attenuated the signal further. Sort of abandoning it. So we didn't exactly get a classic response. The MJO has been disorganized since then and not really much of a factor. CPC MJO desk has mentioned how it's been inactive as of late as well. As such I'm really not trusting any MJO output at this time until something more coherent shows up on multiple cycles. CCKW's and ERW's are the main event in the tropics for now, and that's giving models fits. CPC does mention that if another MJO were to initiate in January, it would likely begin in the west Pacific due to underlying conditions. So if one were to take shape, that's probably not a bad location as a guess. I just don't have any faith in that forecast as of yet. The warm pool situation is more for Feb. If you can have it bump east enough away from it's climo position that's how you can attain a cold Feb. Which has a fair enough chance of occurring as per posts in the main enso thread. La nina is bad in Feb because the climo position of that feature is ~120E. So convective forcing is concentrated mostly in that spot. So you wind up with the Aleutian ridge/ SE ridge regime that is widely known. If you start to shift it away from that and inch it more and more towards the dateline instead, you start working Pacific ridging into more and more of a favorable location. Instead of the climo la nina location. That's one way to get a cold Feb out of a la nina. Which seems like could be happening with a big WWB in progress out there now and perhaps again later in the month, but will it all be enough. It's already made the move away from 120E since October. It doesn't need to be centered on the dateline, just a little bit more east past 150E could work. It's really not all that far off... 2 3 Link to comment Share on other sites More sharing options...

It would be nice to see some southern stream activity get going. None of the models have any of that showing up in the future. Without that, we'll be similar to the cold and dry like Jan-Feb 2025. But as long as northern stream remains active, we can get some clipper action 1 Link to comment Share on other sites More sharing options...
eduggs Posted yesterday at 04:59 PM Share Posted yesterday at 04:59 PM Most of us were lucky last month to get a few minor snow events with cold temperatures and even a borderline moderate snowstorm despite the lack of any classic coastal low tracks. Now we are seeing some back luck with an unfavorable height field forecast out to the end of the mid-range during a peak snow climo period. 1 1 Link to comment Share on other sites More sharing options...

In 2010-2011 , we had a La Nina that was strengthening as winter went on. winter was done by feb 1st. best we could do was an ice storm and a rain noreaster that downed power lines. but it was an epic four weeks....

Another very light dusting of snow this morning. Thankfully they did not come around and do another salt dump. These little snow events are ok but now that the holidays are past I can do without these nuisance events and the persistent cold and wind has become a bit much. I'll be ready do go again in about 10 days! In search of a KU this season but don't see the pattern for one showing up next two weeks at least. Based on the current medium to longer range guidance it looks the anomalies during colder periods would exceed those of the milder pauses in the transient pattern. The 33° to 34° average temperature from EWR to ISP in December felt much colder due to the strong winds. Plus we have become accustomed to Decembers closer to 40° since 2011. But it would have been warmer than average by mid 1800s standards. Monthly Mean Avg Temperature for NEWARK LIBERTY INTL AP, NJClick column heading to sort ascending, click again to sort descending.

Like Sussex said I’ve gone through almost 1/2 a tank a month and my thermostat is never set higher than 66 How well insulated is your home? Poor insulation can really drive up the amount of oil/gas/electric you use to heat your home. Link to comment Share on other sites More sharing options...
Wannabehippie Posted yesterday at 05:15 PM Share Posted yesterday at 05:15 PM 4 hours ago, bluewave said: Looks like a very changeable pattern this month alternating between troughs and ridges in the East for the next few weeks. First week is starting out with a cold trough near our area.Then the ridge builds into the East this week for a thaw.This is followed again with a trough and colder around the 15th. Then another ridge and moderation as we approach the 20th. I am surprised at how many changes we see over North America we see, when the Greenland block weakens a bit, but is in place until at least the 19th as per the models.

psv88 Posted yesterday at 05:17 PM Share Posted yesterday at 05:17 PM It snows everyday now. It’s been quite a start to winter. Cold and 15” of snow by 1/4. With like 8-9 snowfalls. If you like winter weather, you have nothing to complain about 4 Link to comment Share on other sites More sharing options...
