2025-2026 ENSO
so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Since the water year we are still about 4-7" below average. It has only been May that has shown to be above average thus far, decently so at that. April was close but it stuck right along the 95 corridor that managed slightly above average around philly. June has been a bit of a struggle but we need the thunderstorms as we close out the month to produce about 1.5" across the area (PA and northern MD) then we should hit average and maybe slightly above but we have a ways to go before we can say the drought has been knocked out. If we manage near average the next few months we still end up below average for the water year only a tropical system will bring us closer to average or cutoff lows reigning supreme come fall. -

Sure just feel he likes to make sure his ducks are in order. No harm no foul. The WPAC is still warm but not excessively warm as it was so chipping away at it slowly is the name of the game. I would be interested to see if the WPAC starts to fire off any tropical systems coming up here with what could be a minor WWB coming up like we saw earlier this month still no typhoon but at least things are trying to get going. -

Yea there may be a random spot or two that get to 100 at least being shown right now but looks to be potentially our first official heat wave of the season, still a week+ out though so who knows. I will take this lack of heat when I can get it have not had to turn on the AC yet as we have been able to cool down at night properly. May was our first month above average rainfall wise around here in awhile the last time it happened was August of last year and the only reason was because of Debby had that not happened we probably would have gone almost 12+ months below average. -

To each their own just was the first interruption I have seen since the previous Nino. The VP is weakened slightly over Maritime but still in place, though there is weak VP anoms over much of the pacific the last couple months so not sure we get a simple ENSO depiction. Like I have mentioned I could see a warm neutral scenario play out via numbers but we still will have flares of negative ENSO show up just like we had last year with a weak negative ENSO showing up with Nino flares. -

See how it plays out but this is the first time in awhile we have seen a break down of the enhanced trades and the Nina like standing wave. -

If we can see it start to dip into negative around 50mb this will be a good sign of an overall weaker SPV no guarantees of anything other than probably not the near record levels we just saw. A lot of things still need to come together over the next few months. Still have yet to see a tropical system in the WPAC beat out last year but looking further into data it seems like the 8th of June is the latest for tropical storm and typhoon is the 21st. -
Typically the low will occur just before sunrise and the high will occur in the afternoon. Weather conditions of course change this up but to simplify it if you were to have for example 83/62 as your forecasted high and low. The high will occur around 2-5pm (depending on the season) and the low will usually occur 3am-6am. The low temp is usually going into not coming from. So if you happen to have a low of 58 in the morning when hitting that 83 forecast that same day the low going forward is forecast to be 62 for the next morning. So the day before the forecast would have maybe looked like 78/58 going into the 83/62. When the low or high hits it may just be for a brief moment and not a multi hour situation. Hope this helps.

While oceanic temps have definitely increased probably the most drastic of changes has been in the Arctic over the last 50 years I feel this probably is the biggest reason we have been having issues with pattern semblance over the last decade or two, more notably. It may very well be the reason for such changes to the PDO state but im not ready to make those accusations or conclusions. Over the last 5 years the Antarctic has suffered rather drastic changes to the ice sheet I wonder if we start seeing similar results within the southern hemisphere as we have seen in the northern with the idea of permanence taking shape. -

RONI peaked in 2015/16 NDJ of 2.38. ONI of ~2.6 RONI peaked in 1997/98 SON also at 2.38. ONI of ~2.4 https://www.cpc.ncep.noaa.gov/data/indices/RONI.ascii.txt Im personally still not on the RONI bandwagon as being a reasonable indicator of what will occur but to each their own. This type of atmospheric pattern in 2023/24 was closer to the strong/super Ninos even with the RONI showing barely strong status. I included 1972/73 as that was the last deeply -PDO/ +ENSO we experienced of course it is apples to oranges as nearly 50 years of oceanic warming have changed things up a bit. -

We had a strong/super El Nino just 2 years ago and wasn't able to break it. So what you would be suggesting is a higher than 2015/16 scenario given the WPAC has still warmed during that time frame which would mean an ONI above ~2.6C probably closer to 3C consistently over several months to reset the system? Honestly I feel that is not reasonable if 2 El Nino, as strong as what we have seen one being nearly the strongest we have physically recorded, can not cool the WPAC having a stronger one won't change that fact. I feel we need to give it time to see how this all plays out and feel it is too early to draw conclusions on something to say permanence has set in. Im not trying to play a gotcha moment if it does in fact change up over the next few years to decade or stays exactly the same. Would rather let it play out and get better understandings versus making such claims one way or the other. It would be awfully weird to make these claims that things have changed for the worst and then we get another 5-10 year block of crushing snows again. -

We would need to start seeing signs emerge if it was to tilt one way or the other more than just neutral. Nothing is catching my eye and overall as Bluewave has said it does look like things want to try to progress eastward in the tropics and switch things up a bit but the subsurface would not be super conducive to produce a weak or moderate El Nino right now if that were to actually start to show up. I think it is important to remember that La Nina is just a further enhanced state of what base state looks like as 40/70 has mentioned it is important on location of oceanic and even atmospheric features that dictate overall how things progress. We are pushing out from the spring barrier so we should start to see some signs emerge, what they are yet is anyone's guess. I gotta get to bed though I work tonight so ill be back on later. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
We have seen this back and forth so much recently I am not confident this holds at all but for the mean time yes we are still having a La Nina atmosphere, even while weak to non existent SST profile, still holding the helm. Slow fade into Fall to neutral/warm status and maybe even a quick flare up of Nino like conditions atmospherically. No guarantee but the way things want to try and setup it seems this is possible. The biggest tell tale right now is the lack of WPAC typhoons should hit the record with no issue. Thoughts haven't changed in that aspect. There is no doubt though the warm pool has largely shifted now comes if it rebuilds in any meaningful way or we have another episode of end of summer/ fall push again. Yea I guess it will technically still register ENSO neutral but with a flare to Nino style is my current thought. We really may see the battle re establish again where we see a back and forth like last year. MJO is dead so it will be interesting if we follow a similar path as last year where a weak wave started moving again come end of June into July. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Anyway here is the last month and a half of TAO data showing the increase in OHC GAWX just showed. This should still maintain a Nina-like atmosphere through at least most of the summer would not be surprised if we start to see some flare ups of Nino-like progression into Fall just not enough to flip the script. -

So we are just done talking about ENSO in an ENSO thread and this has now become a historical catalog for snowfall accuracy and debating climate? -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Since this thread turned into a semi Climate thread warmer oceans and atmosphere allow for more water vapor leading to hefty rain events. Feast or famine seems to be the name of the game as of now with weather patterns. Just hope we have not turned on the faucet like we did in summer of 2018. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Only has been two ULLs one at the end of April to the first few days of May then we had about 2-3 days of clear weather, small system around last weekend (Friday/Sat) that zipped through and just this one the last about 3 days. It seems like it has been a lot longer but it really hasn't been extraordinary by any means. Again training and orographic lift played huge roles in this issue in western VA/ Eastern WV and Western MD unfortunate for sure but a reality of living near mountains. Again I hope we continue this rainfall we are still nearly 7-8" below average on the water year around here we should have better soil conditions to help with this next bout of rain come next week. Largely this weekend will not be as threatening as once looked a couple days ago too much west flow down here, maybe a little something from Central Pa into Southern NY early Friday into early Saturday. -

That is not a very long time in a cutoff low situation. BTW for your snowfall thought you are talking about two completely different seasons with two completely different jet configurations. Rain in winter is usually in and out just as quick as snowfall. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Training is the name of the game with this one not sure I would call this a stuck pattern but to each their own. By definition what length of time do you consider a stuck pattern? Yes when you get 2-3" of rain within 24 hours anytime of the year it won't be a great situation let alone coming after such a long dry period the ground can not quickly revert to a sponge. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
We have only had appreciable precip within the last maybe 3 weeks at this point. This will be the first month, at least in the BWI area, that we have seen near to above average precip in nearly 9 months. If it weren't for Debby last August we would have had almost a year and some months of below normal precip and we really didn't get a whole lot from Debby that was into the mountains (WV, VA) and Western PA. It is a bit late for us to be getting these ULL patterns but not unheard of. I would love to see us finally get back to at least average over the next couple months and hope that this is not just a fluke situation. -

so_whats_happening replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Yea big reason I feel we see a brief warm neutral state arise by winter time I do not believe the atmospheric state will have enough tipping to allow a Nino like atmosphere throughout but it could very well be a back forth scenario just as we experienced this year. Unless we start to see some pretty drastic reversals occur within the subsurface over the next two or so months. -AAM in full swing which would indicate at least atmospherically there should be a La Nina signal still well about. This will be important in the coming few months for the hurricane season. As others have mentioned, with a -AAM, we should still be seeing a pretty decent PV as we get into winter although it will be interesting to see what happens if we do indeed flip the QBO state by fall/winter. I would not expect record levels like we saw this past year. I do want to see how the pacific typhoon season sets up have yet to see a storm in the WPAC so we may very well see a record again for the latest system to form. The monsoon looks to be rather weak but starting up toward the end of the month across SE Asia. It looks like we continue with the cool tongue/ -PDO look from the Baja to the central Pac with brief bout of warming into Nino 1+2 and 3. Been awhile since I have looked but thoughts a modoki/ west based la Nina pattern trying to setup? -

https://psl.noaa.gov/map/clim/sst.anom.anim.week.html Yea we are starting to see some impressive warming on the eastern portion of the warm tongue that has been ever present (due north of Hawaii and SW of the Aleutians). What is interesting to note is the shift of these warmer waters around Japan to areas further east. Many areas around mainland China, Koreas, and near Japan have actually held near average to just slightly above average, nothing like what we saw this time last year where many areas were about 2-4 above average widespread. Another region to also look at of recent is the cooling down of waters near the maritime continent, again not quite near average but not raging warmth like we have seen occur. The Baja has been interesting to watch hold through most of the late fall/winter time frame this area finally linked up with the -ENSO state so I would not expect it to be crushed so quickly. I do still think there is a chance at a warm neutral winter next year as we start to try and erode the equatorial subsurface over the next 6 months+, prospects of El Nino development should go up for 2026/27. I will be curious to see how the western Pacific Typhoon season goes. So far we have not seen a single storm form and we may start to run toward the record again. The idea I have been discussing has been a potential booming late season for the West Pac but probably still end up below normal.
