Have to wait and see what these look like the next week or two with a KW moving across the IDL,3 could take a big spike upwards

Subsurface continues to warm east of the IDL,into the IO there looks to be a Rossby Wave that will weaken the ongoing winds for a few days but towards the Mid month they look like they will return once again.By the looks right now the MJO seems to reappear in East Afica towards the middle of Nov then stall out once again into the western IO,have to wait to see if it might happen,but sure looks that way right now

The BOM and SINTEX have different readings which you'd expect anyways of the DMI.BOM shows the DMI as been the highest ever a week or two ago at( 2.16.)While Sintex shows the highest peak was Nov 14,1997 at (2.202). 1994 by SINTEX came in 3rd when it peaked in Mid Oct of that year at (2.082) During or after the peak both of these years 1994,1997 the ONI rose into into a stronger Nino into winter on the ONI 1994 went into a moderate Nino 1997 went into the the 2ND strongest Nino ever The following year 1995 and 1998 went into a Nina in" JJA." on the tri-monthlies (-0.5) IN 1995 which ended up a moderate Nina into the winter months (-0.8) IN 1998 which ended up a very strong Nina into that winter but this was a very long lived Nina in whole that last until early 2001

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1126 AM CDT Wed Oct 30 2019 Valid 301630Z - 311200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS CENTRAL GULF COAST STATES TO THE CUMBERLAND PLATEAU... ...SUMMARY... Isolated damaging winds and a brief tornado are possible across parts of the central Gulf Coast States to the Cumberland Plateau through early morning Thursday. ...Central Gulf Coast to the Cumberland Plateau... Two primary convective scenarios are apparent through the period. A leading low-level warm advection regime is supporting a swath of ongoing showers with embedded thunder from the central Gulf Coast through AL. A belt of strong low-level flow centered on northern AL will pivot northeast, becoming increasingly separated from the gradient of weak buoyancy to the south. Poor mid-level lapse rates and pervasive stratus should support only meager buoyancy overlapping where enlarged low-level hodographs can persist. While it seems unlikely that any of the clusters will have sustained intensification, a low probability risk for locally strong gusts and a brief tornado will exist through the afternoon. Upstream convective development will be tied to an initially weak warm conveyor region across the Lower MS Valley. Some thinning of cloud coverage is apparent across southern LA into far southern MS which should aid in a confined plume of moderate buoyancy (MLCAPE of 1000-1500 J/kg at peak heating). This should aid in late afternoon/early evening storm development just ahead of a weak surface cyclone tracking from the Sabine Valley to the Ark-La-Miss. However, the bulk of strong mid/upper-level flow attendant to a shortwave trough ejecting from the southern Rockies to the Lower MO Valley will lag behind the warm sector through mid to late evening. Cyclogenesis will ensue farther north tonight as tropospheric flow amplifies. However, stronger shear and forcing for ascent should remain misaligned north of where the northern extent of weak surface-based buoyancy can advect across portions of northern MS/AL to middle/eastern TN. The most likely scenario is still for low probability coverage of wind/tornado hazards across the Lower MS and TN Valleys, though the region will be monitored for a possible level 2 categorical risk in later updates.

Not much change this update

By the CFS the IOD is showing to maybe finally breaking down past the Mid month.the RMMM's will be nothing but noise until then.still looks like at least some sort of WWB into the 2nd week of Nov that could possibly bring a Kelvin east of the IDL.Maybe and seemingly the MJO will become relevant once again and move past the mid month and more into the 3rd week of Nov.

Have to wait and see upcoming,both the GFS and Euro this afternoon shows a chance of severe thunderstorms even Wed NOW.The last run of the Euro, last nights 0Z run compared to this afternoons run has sped the front up almost 6 hours and now brings it across the Mid Valley now 18z Thursday and then to the east but it strenghtens the LLJ as it seemingly crosses east of I-65,GFS is still faster and WPC shows it as the outlier.Looks like the heaviest rain by the Euro is east of I-65 could get 3-4",could even be higher with convection

Those straight line winds must have been howling

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0335 AM CDT Sat Oct 26 2019 Valid 291200Z - 031200Z ...DISCUSSION... Recent runs of the medium-range guidance have come into better agreement regarding the position of a deep and broad upper trough expected to be over the CONUS on D4/Tuesday. Model consensus now places this trough from the Hudson Bay through northern CA at 12Z D4/Tuesday. Model consensus regarding the overall evolution of this upper trough is also good, although the speed of eastward progression differs. The faster GFS solution is currently the outlier. Progression of this system and its attendant cold front will dictate the quality of moisture return ahead of it as well as the location for any potential severe thunderstorms. Some severe threat may materialize across the Southeast/TN Valley mid-week but model differences are too high for enough forecast confidence to outlook any areas.

Must have been a brutal warm winter that winter in our parts with the PDO crashing in fall into winter https://www.tandfonline.com/doi/abs/10.1080/00431672.1952.9933398?journalCode=vwws20

Would like to see a good analog for this winter pattern,doubt you'll find one,last season we was warm and wet.The IOD from Sintex and even the CFS don't show the IOD breaking down soon,but Sintex does show it weaken in which i said above to + 1.104 in mid Nov.What's even more odd the strongest reading in Nov was back into 1997 in a strong Nino where it hit 1.528,there has never been into Nov this reading and yet alone over +1 ever since 1870,really think the SST'S are going to be much warmer than what some of these seasonals are showing upcoming,right now anyways.

Have to wait and see into next weekend,WPC seems to be going half way with the Euro and GFS but right now the GFS is much faster.Euro shows the upper level ridge building into the Valley,with a more Bermuda high with a warm front lifting into the lower OV, this would put the Valley into the warm sector,but the lapse rates look really poor right now.But either way what the Euro shows right now this should be some sort of flood threat somewhere in the Valley with the low level shear getting cranked up along with the LLJ,least that what it shows right now

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
