Should keep an eye out seemingly towards the 2nd week of Nov,seems signs of another WWB upcoming which could help initiate a Kelvin,into east of the IDL

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 AM CDT Sat Oct 19 2019 Valid 211200Z - 221200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS MONDAY ACROSS PARTS OF THE LOWER MISSISSIPPI VALLEY... ...SUMMARY... Severe thunderstorms are possible Monday across portions of the lower Mississippi Valley, into portions of the lower Ohio Valley, posing a risk for damaging wind gusts and perhaps a few tornadoes. ...Discussion... Rather amplified large-scale troughing over the interior U.S. may take on more of a negative tilt while progressing across the Mississippi Valley during this period. Smaller-scale embedded perturbations/developments remain more unclear due to sizable spread within model output, but it does appear that there may be substantive further deepening of the primary associated lower/mid-tropospheric cyclone. The center of this feature is expected to migrate from the mid Missouri Valley into the Upper Midwest Monday through Monday night, with an occluding surface front surging east of the Mississippi Valley toward the Appalachians. Lapse rates within much of the moistening portion of the warm sector of the cyclone are generally forecast to remain weak, which may limit CAPE to around 500-1000 J/kg within a pre-frontal plume across the lower Mississippi Valley into the lower Ohio Valley. South to southwesterly lower/mid tropospheric flow may include 50-70 kt at 850 mb, and 70-90+ kt at 500 mb, but there may be a tendency for the strongest deep-layer mean wind fields to shift north of the destabilizing warm sector early in the period. Still, there appears potential for the environment to become conducive to the development of a combination of one or more broken lines of storms and discrete supercells, particularly during the day Monday across Louisiana, Mississippi, and adjacent portions of southeast Arkansas and western Alabama, into portions of middle Tennessee, which probably will be accompanied by a risk for damaging winds and a few tornadoes.

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

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

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...

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

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

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.

Agree,SE also is getting into a severe drought,we really need something to thump them hard

Surface and subsurface east of the IDL continue to warm,tho it's still cool into the subsurface around east of 120W.CFS shows a WWB making it slightly past 120W before it meets a Rossby wave and weakens it mid month,but this could help initiate a KW east of the IDL,so if were to be right you'd see some slight warming into 3 past the mid month i'd think

Seems like the GFS and Euro met somewhat halfway last night,weak and weaker instability.Nothing much to see right now.Good news i reckon seems like over an inch of rain,least right now.

Be nice to watch and hear some good t-storms Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CDT Mon Sep 30 2019 Valid 031200Z - 081200Z ...DISCUSSION... A progressive pattern at mid/upper levels is forecast through the extended forecast period. An upper trough/low should move quickly eastward across the Great Lakes, OH Valley, Northeast, and Mid-Atlantic on Day 4/Thursday. A cold front is also expected to shift quickly eastward parts of these regions. Minimal instability is currently shown by medium-range guidance ahead of the front, owing mainly to poor low and mid-level lapse rates. Therefore, severe potential Thursday afternoon ahead of the front appears low. Another upper trough should amplify and shift eastward across the western CONUS and into the Plains from Day 4/Thursday into Day 5/Friday. There is still variability with the amplitude of this feature by Day 5/Friday, which impacts the degree of low-level mass response and moisture return across the Plains. Some severe risk may ultimately develop Friday evening/night across part of the central Plains, but this threat may remain rather isolated. There is currently too much uncertainty regarding instability and the evolution of the upper trough to include any probabilities for organized severe thunderstorms. Differences regarding the evolution of the upper trough across the Plains and eastern CONUS become much more pronounced from Day 6/Saturday onward. Still, depending on low-level moisture return, there may be isolated severe potential across parts of the southern Plains into the lower MS Valley, TN Valley, and Southeast next weekend into early next week ahead of a cold front. However, overall predictability remains far too low to include any areas at this time.

3.4 is back to 0.5
