This should update in the morning,but you don't see those cold SST'S -2 down into the subsurface no more,you actually see a warm nose poking in 120-130 W
-
And you are right,we went into a Nino into winter.The OBS today from Jamstec is at +1.236 right now today by mid Nov it's showing to be at +1.104

Positive IOD is the strongest since 1994,1997 and 2006.no signs of letting go right now. During these years and using the starting point of the last ONI this year with "JAS" which is right now at 0.1,but is subject to change possibly in the future. In the year 1994 during "JAS" the ONI started at +0.4 and at the end of this year "OND" ended in a moderate Nino 1.1 During 1997 during "JAS" 1.9 and ended up being the 2nd strongest Nino 2.4 into "OND" based on the ONI since 1950 2006 "JAS" probably started closer than any other year "JAS" 0.3 and ended up close to a moderate Nino in "OND" 0.9

Subtle changes each run by the Euro.OZ run Euro wants to develop a potent shortwave into the lower MS/Valley which comes through west of Nashville OZ Tuesday. Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0350 AM CDT Wed Oct 16 2019 Valid 191200Z - 241200Z ...DISCUSSION... Day 4/Saturday: A weak upper shortwave trough over eastern portions of the Plains on Saturday will quickly lift northeast. At the surface, a weak cold front will sweep across the Upper Midwest/Great Lakes while stalling over the southern Plains. Meanwhile, guidance varies on the intensity of a tropical disturbance as it tracks near the northern Gulf coast/southeastern U.S. on Saturday. Reference the Tropical Weather Outlooks from the National Hurricane Center for more details on this system. How this low evolves could influence severe potential across parts of the northern and eastern Gulf coast states into GA/SC on Saturday, though severe potential appears low at this time. Days 5-7/Sunday-Tuesday: Severe potential is expected to increase on Sunday as a more intense shortwave trough ejects eastward from the Rockies into the Plains on Monday. Strong deep-layer southwesterly flow will develop from the southern Plains to the Upper Midwest as the trough deepens over the Plains. The ECMWF and GFS are in better agreement over the position of an intensifying surface low compared to yesterday, with the low tracking across SD through the afternoon before lifting northeast into MN overnight. A trailing cold front will push eastward across the Plains, with some timing differences among various guidance. Despite this, models are fairly consistent in moist return flow bringing 60s surface dewpoints northward to at least the Ozark Plateau eastward toward the Mid-South. At least a narrow corridor of severe potential is expected ahead of the cold front where a favorable combination of instability, steepening midlevel lapse rates, strong shear and upper forcing for ascent will align. Over the past few days, this corridor has been most consistently indicated by medium-range guidance across parts of north TX, eastern OK into adjacent parts of KS/MO/AR. Confidence has increased sufficiently to include 15% severe probabilities, through this area likely will change some in come days as forecast details hopefully become more clear. A severe threat could continue into Monday across parts of the mid/lower MS Valley vicinity eastward toward the Appalachians as the cold front continues to surge eastward. A very moist airmass will be in place downstream of the front, but timing differences in the eastward progression of the front among various model output is large, decreasing forecast confidence. The cold front will continue to shift eastward across the eastern U.S. and is expected to move offshore most of the Atlantic coast by Wednesday morning. Depending on timing, some severe threat is possible across parts of the Carolinas and Mid-Atlantic, but again, confidence remains low.

JAMSTEC ,more central -west based but not as warm as the last update where it looked like a more weak Nino,now looks more neutral,not really a whole lot of change tho with the 2M's from the last update

Tennessee Valley 2019 Fall Speculation/Forecasting
jaxjagman replied to AMZ8990's topic in Tennessee Valley
Hagibis is still going to be a player into next weekend along with seemingly a Kelvin Wave into the Gulf which is being shown right now,next weekend and maybe into the first of the week after right now to me could be rather volatile- 574 replies

Ongoing WWB east of the IDL has been warming 3.4,this should last maybe a couple more weeks until the WWB passes and weakens with even more warming east of the IDL even into region 3 also even have to see what a Kelvin does,after this nothing really showing up other than some weak easterlies into Nov seemingly right now,Should see 3.4 get bumped up from 0.5 up tomorrow when the weekly ENSO update comes out

Tennessee Valley 2019 Fall Speculation/Forecasting
jaxjagman replied to AMZ8990's topic in Tennessee Valley
MJO signal looks weak again.Just when you would think the IO would die off again it get's resurrected by easterlies killing the MJO signal.This also looks like this could be the strongest easterlies upcoming the next several days into the IO,maybe it will move forward the end of the month?See what happens,looks like a warm up into the end of the month into the first of Nov tho- 574 replies

Tennessee Valley 2019 Fall Speculation/Forecasting
jaxjagman replied to AMZ8990's topic in Tennessee Valley
Pattern looks really volatile,not only do you have Harigis that's going to spin off Japan you have to look into the GOM for at least a tropical wave which could develop from a Kelvin,good luck with the long range- 574 replies

3.4 and 3 are slightly rising today.WWB headed east of the IDL today looks to strenghten some what and kicks up a Kelvin,should have to wait and see tho what kind of upwelling it does as warm as the waters are into the subsurface into 3.4,not much going on after this seemingly for several days so eyes should be on if the MJO gets finally active which it seems could be finally moving into the IO
-
Hagibis is crushing Japan,some amazing pics being posted on twitter https://twitter.com/search?q=japan&src=typd

Like to see the next update from CPC.The TAO shows warming into the subsurface getting into R3 today from a more suppressed Kelvin.The CFS still shows a WWB getting into R3 around mid month but without a more robust Rossby as it was showing earlier, so this WWB goes further east, so this would/could help kick up a CCKW as being shown
-
But this can be just as volatile as the pattern we are seeing right now in 1.2

Slight push to the west with the warm SST'S at the surface and subsurface on this map.Kelvin passed 3.4 and into 3 so they have been cooling some the past couple days.The cold pocket though east of 120W in the subsurface in region3 keeps getting smaller and smaller
-
Seasonals are coming out,NMME looks to cool right now and GOES is certainly the outlier.Think if i were to make a bold prediction with the ENS0, GFDL FLOR would be my top choice going into winter,by these models
-
looks more wind by the outflows,either way,HRRR is not doing very well,we are fixing to get some good rains soon into the Mid Valley Tornado Warning TNC023-039-071-077-109-070445- /O.NEW.KMEG.TO.W.0033.191007T0400Z-191007T0445Z/ BULLETIN - EAS ACTIVATION REQUESTED Tornado Warning National Weather Service Memphis TN 1100 PM CDT Sun Oct 6 2019 The National Weather Service in Memphis has issued a * Tornado Warning for...

2019 ENSO
jaxjagman replied to AfewUniversesBelowNormal's topic in Weather Forecasting and Discussion
Think in the long range you should see what this WWB does before a robust Rossby wave kills it off around 120W into region 3,this could really warm region 3 up seemingly and even spawn up a new Kelvin with this, CFS has been rather consistent with this -
2019 ENSO
jaxjagman replied to AfewUniversesBelowNormal's topic in Weather Forecasting and Discussion
Not sure if that is going to be right,these SST'S seemingly keep getting warmer east of the IDL into the surface and into the thermocline,guess we'll see.I can see the warmth more basin wide tho -
2019 ENSO
jaxjagman replied to AfewUniversesBelowNormal's topic in Weather Forecasting and Discussion
I usually just post on our sub-forum every once in awhile post here,but why do ya'll keep thinking this will be a west based Nino and not a wide spread Nino,the subsurface to me is just brutal warm to suggest this -

CFS continues to be consistent with a WWB east of 120W then runs into a robust Rossby and weakens it,still have to watch out for a potential to initiate a KW,the subsurface continues to warm east of the IDL.

Tennessee Valley 2019 Fall Speculation/Forecasting
jaxjagman replied to AMZ8990's topic in Tennessee Valley
Be nice to see the phoon re-curve further east for a change.Going with the Euro it's going to hit SE Japan and then get absorbed by the half way decent trough moving through East Asia around D8, by the Euro this afternoon,we could possibly have a trough in the east,roughly around 15-16 days give or take if it is right- 574 replies

Some convection around around our area,getting a little rain so far.HRRR shows the LLJ kicking up along with the low level shear, in a few hours,should kick up some good rains west of I-65 later on tonight,it's good news for us as we went into a severe drought last week,per the drought monitor
