NCEP ensemble forecast shows deep La Niña coming

We know that we are currently in a La Niña pattern by the various maps and graphs we have on the WUWT ENSO page, for example this one:

clickable global map of SST anomalies

But have a look at the ensemble forecast, updated yesterday. The average line which has now dipped “off the scale” of the graphic from February-March of 2012:

It means nothing – as we have all been taught, el Nino is climate, but La Nina is just weather.
From today’s China Daily under my hotel room door this morning:

This is not one of the two CFS graphs (V.1 or V.2) that is reported in the latest (10/17) weekly ENSO discussion update. http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/lanina/enso_evolution-status-fcsts-web.pdf
Anyone know what this version represents, and why it’s not used in the report ? Perhaps this is considered an outlier at this time ?

October 17, 2011 9:45 am

If recollection serves me right this means that I better be ready for yet another wet and cold winter. The wet part is ok (up to about 200% of the normal rainfall that is, with a one day rain event no greater then 4″) as I obtain my water from a well. My house was built out of the flood plane and my culverts do fine most of the time.
The cold part on the other hand is getting old and expensive- as far as fuel costs to transform my living spaces into something habitable.

It’s going to send global average temperatures, and particularly tropical temperatures, through the floor. We’ll be needing an explanation of how climate models don’t necessarily predict that climate change causes warming.
It would be a good opportunity for Dessler, Spencer, and other interested parties to make some predictions about top of atmosphere radiation.

Agreed. And yet if I’m understanding Joe B. correctly, a strong la nina will paradoxically also help a warmup in the northeast come feb/march…But I’m hazy on that. I could have it wrong.

They stopped looking for the missing heat a while ago, shortly after the ‘travesty’ comment was made.
What they are looking for now are excuses. A couple of those balloons have been floated already. Rest assured that ‘global warming’ will be found hiding behind every snowdrift, and it will be “worse than we thought”.

PRD
October 17, 2011 10:18 am

It means the climatology maps for South Central USA will need to be redrawn to reflect a near desert environment. Old trees are starting to die around here in NW and West Central Louisiana and East and Southeast texas. I’m talking about oak, pine, and hickory. This is due to two years of extreme drought with not enough rain to do more than moisten a few inches of topsoil at a time. Post holes dug down 4 to 5 feet deep for cornerposts show hard and dry clay. Hay for livestock is selling for over $100/bale for round bales shipped into the affected areas. The last significant precipitation events we received were a winter snow of 5 to 8 inches, then a storm event at the end of April accompanied by a flurry of tornadoes and hail. The avg precip from that was less than 1″. When checking the NWS office, I have no idea where they get their precip totals, they must be adding in an occasional morning dew.
This is what the little girl gives us…

October 17, 2011 10:19 am

Given that La Nina’s typically recharge the Ocean Heat Content in the Pacific, would we expect an exceptionally strong La Nina to add more heat than normal? Would we then expect a strong than normal El Nino within a few years as a result?

After listening to Joe Bastardi, It’ll be the next elnino that will be difficult for North America. If an elnino comes on just before winter warm moist air from the pacific will be drawn toward the cold continental air mass.
Warm moist air rising over cold winter air. Should be interesting.

March 27, 2011, James Hansen & Makiko Sato
The NOAA web pages giving weekly ENSO updates predict a return to ENSO–neutral conditions by mid–summer with some models suggesting a modest El Nino to follow. We have been checking these forecasts weekly for the past several years, and have noted that the models almost invariably are biased toward weak changes. Based on subsurface ocean temperatures, the way these have progressed the past several months, and comparisons with development of prior El Niños, we believe that the system is moving toward a strong El Niño starting this summer. It’s not a sure bet, but it is probable.
Thanks guys, please can we have our money back

There’s an interesting ENSO development for this NH winter/spring…

Thanks for the graph, I think.

October 17, 2011 10:32 am

To all “non AGW” (i.e. deniers) people here: never forget that if the global average temperature rises because of El Nino then it’s global warming, if instead the global average temperature falls because of La Nina then it’s climate disruption. Either it’s hot or cold, it doesn’t matter, you’re screwed!

October 17, 2011 10:33 am

I’m guessing this means another year or two of extreme drought in Texas?

And in the Southeastern US so buy up a supply of peanut butter because it is going to get scarce. Probably a warmup in New England but maybe a huge blizzard or two in Western NY. Lots of snow and cold in the Northern plains. The Pacific Northwest will depend on exactly where the jet stream settles. I have been watching an interesting “cut-off low” off the West coast for several days now. You can see it clearly on the GOES water vapor map: http://www.ssd.noaa.gov/goes/west/nepac/flash-wv.html

Don Easterbrook
October 17, 2011 10:51 am

If that’s not bad enough, click on the NOAA satellite SST imagery above the la Nina curves. The PDO (Pacific Decadal Oscillation) flipped from warm to cool in 1999 and has stayed there ever since (hence a decade of gradual cooling). The cool water off the coast of N. America is now larger and cooler so look for another bitter winter, maybe worse than last year and continuing cooling after that. This is just weather, but over the past decade, the temps have followed the long-term cooling pattern very well (as predicted in 1998). Guess we should be careful what we wish for!

The Farmer’s Almanac says cold and snowy for the southeast US. Joe Bastardi said, when he was working at Accuweather, that in a multi-year La Nina event, the second winter is always colder than the first winter. But in an earlier video, he said the cold the southeast US experienced was the first time such a pattern ever occurred on record. Living in the southeast US I have noticed that there are more acorns this year than last year. Winter isn’t long now, we shall see what happens.

It’s clear evidence that we need to spend a lot more dollars mitigating climate change.
In Europe it’s going to be cold this winter. That means folks will be burning a lot more energy to stay warm and thereby produce lots more CO2 which, as we all know, is the most harmful man-made chemical yet discovered. Unless we get that CO2 under control this winter, you are going to die.

October 17, 2011 11:39 am

It is uncommon for La Nina to deepen into the spring. It usually bottoms out in Dec-Feb. As for NCEP forecasts, they showed -2.5 values the last time, too. Didn’t quite work out that way….

Tim Clark
October 17, 2011 11:45 am

It means a very dry winter and spring, plus 6-9 months more after it rises above -.5 on the graph above. This is for that part of the US below the jet stream in the central states.

October 17, 2011 11:48 am

As someone, along with my partner Joe D Aleo, who said back in May this La Nina was not over as the cold PDO Ninas last 21 months, and it would be back, let me also say the NCEP enso forecast is a joke. It had a warm episode developing back in May and though not as bad as Nasa and Hansen, it is a lousy model and only reacts to current trends, much like the longer term climate models. You will find that the frontier research and euro models destroy it routinely.
That being said, the across the board forecast of a cooling amo is huge! I am on record as saying the objective global temp will drop to at least -.15C by march, though its highly doubtful the Enso 3.4 goes below -1.2… The bigger news is in the atlantic!!!! See global temp forecasts there against last year… its night and day.
The big fall is coming in the amo and also the global temps.. The modeling is certainly showing the tropical atlantic cooling in a much more rational fashion than its way overdone ( IMO) enso 3.4.
One should go back to the archives of the CFS and remember who said what and when. Followers of Joe D and I on Weatherbell know from the get go that the basis of our fall and winter forecast was for the nina to still be around, but that the CFS is now way overdone and reactionary.
The cooling atlantic is not the end of the overall warm amo, but is in line with what started happening in the 1950s, as is the PDO. In 10-15 years, this whole silly climate debate should be over as once both of them are cool in tandem, they will not have a leg to stand on. But be patient and dont overdo, and continue to fight on facts with comparison to what is the smoking gun of the climate fight… the pattern of the 1950s and the similarities from sea ice to overall weather patterns to what we are seeing today. When studying that, you will really see something remarkable.. more so than a computer model that is out of control

October 17, 2011 11:56 am

To Tom_r, see the link in my previous comment, here you have a statistic over “succeses” for the previous model forecasts: NCEP did a MUCH BETTER jon at predicting the 2010 La Nina.
In fact almost all other models failed to tell in advance that a La Nina was coming in 2010, and they are not saying much about a la nina now either.

Well, if it’s the same as last winter, Denver will be very dry and the mountains will be slammed with snow. Great, if you’re a skier!
We already planned on watering frequently this winter but I sure hope we have a cool wet May like last year to make up for it. I don’t usually have higher water bills in the winter.
We’ve already had a very dry autumn. We finally had a little rain today. That makes 2 days with rain in the past 3 months. The good news is that we may skip the heavy wet October snow that usually breaks all the tree branches.

October 17, 2011 12:17 pm

Was going to flag this in T&N myself yesterday, but it was a lazy Sunday…
The NCEP model forecasts tend to have a fairly wide margin of error from memory over the past 18 months – like almost all models, they struggle to predict turning points with any degree of accuracy. In the early months of the year, once the low point of the first dip had been passed, most models were moving into neutral/mild Nino territory with a levelling, but I don’t think any were showing La Nina to be back by now.
What you can say with reasonable confidence is that, once a trend is established by September we get a continuation of the existing trend until at least the January after, when the trend usually reverses. Question is, will 2012 see a full year of upswing into Nino conditions like 2009, or are we set for a reversal of the 2002-07 period with the occasional Nada punctuating an almost-continuous Nina?
I don’t know if anybody out there is already doing this, but I’ve started to keep a document screencapping the ensemble forecast charts every fortnight. Be interesting to report back in six months to see how they’ve been getting on (be even more interesting if someone’s actually been doing this for a year or more…)

Very, very cold subsurface anomalies appearing in eastern ENSO regions. An east-central based Nina looking likely again. In terms of Winter, if the greenland block returns and gets established…look out!

And perhaps even more interestingly, it doesn’t appear to be due to displacement west of warmer water, as the anomalies there are dropping too. Might it have been instead giving up heat across the width of the ocean to the atmosphere? Might this explain the slightly-unexpected spike in the UAH temps since June? If so, we really are headed for a spell of cooler temps…

In the UK, during the last couple of months, there has been concern at the rising costs of energy and the stretch that this will place on households. The BBC has interviewed several people regarding this (politicians on both sides of the political spectrum) and they have offered stated that this winter will be a very cold winter. If the BBC will allow interviews where the interviewee discusses very cold winters, one knows that the forthcoming winter is truly expected to be bad. The BBC normally oinly runs with stories that fit the warmist mantra.
It does appear that the UK is preparing for a cold winter this year. If that hapopens, it will be 3 very cold winters in a row. So much for snow being a thing of the past, and that the UK would be experiencing milder winters.

“, our illustrious coalition Secretary of State for Energy and Climate Change, Chris Huhne, calms the nation by simply telling us all to shop around and switch suppliers, on national TV.”
For crass stupidity and ignorance of even basic economics this man takes the biscuit on an almost daily basis. After a weekend of lambasting the Energy Suppliers for making £125 profit per customer on an average spend of £1325 he appears in our papers and on our screens to tell us to change supplier and by selecting a different tariff cut our bills by more than £200.
Conveniently he omits to tell us that through VAT and ROC the government is taking at least £200 from every household and that even this imposition will go very little way towards providing the £200Bn needed to pay for the outrageously subsidised and inefficient renewable energy sources that he favours.

October 17, 2011 1:04 pm

Hi Joe Bastardi!
Due to the lack of succes from other models and better succes for CFS/NCEP predicting the 2010 La Nina, then i would note at all rule out that CFS/NCEP is indeed going to be closest, we will see much lower than -1,2K in the spring 🙂
That my guess, see fig 2 how hopelessly most other models has “predicted” the 2010 La Nina:

SAID HANRAHAN by John O’Brien
“We’ll all be rooned,” said Hanrahan,
In accents most forlorn,
Outside the church, ere Mass began,
One frosty Sunday morn.
The congregation stood about,
Coat-collars to the ears,
And talked of stock, and crops, and drought,
As it had done for years.
“It’s looking crook,” said Daniel Croke;
“Bedad, it’s cruke, me lad,
For never since the banks went broke
Has seasons been so bad.”
“It’s dry, all right,” said young O’Neil,
With which astute remark
He squatted down upon his heel
And chewed a piece of bark.
And so around the chorus ran
“It’s keepin’ dry, no doubt.”
“We’ll all be rooned,” said Hanrahan,
“Before the year is out.”
“The crops are done; ye’ll have your work
To save one bag of grain;
From here way out to Back-o’-Bourke
They’re singin’ out for rain.
“They’re singin’ out for rain,” he said,
“And all the tanks are dry.”
The congregation scratched its head,
And gazed around the sky.
“There won’t be grass, in any case,
Enough to feed an ass;
There’s not a blade on Casey’s place
As I came down to Mass.”
“If rain don’t come this month,” said Dan,
And cleared his throat to speak –
“We’ll all be rooned,” said Hanrahan,
“If rain don’t come this week.”
A heavy silence seemed to steal
On all at this remark;
And each man squatted on his heel,
And chewed a piece of bark.
“We want an inch of rain, we do,”
O’Neil observed at last;
But Croke “maintained” we wanted two
To put the danger past.
“If we don’t get three inches, man,
Or four to break this drought,
We’ll all be rooned,” said Hanrahan,
“Before the year is out.”
In God’s good time down came the rain;
And all the afternoon
On iron roof and window-pane
It drummed a homely tune.
And through the night it pattered still,
And lightsome, gladsome elves
On dripping spout and window-sill
Kept talking to themselves.
It pelted, pelted all day long,
A-singing at its work,
Till every heart took up the song
Way out to Back-o’-Bourke.
And every creek a banker ran,
And dams filled overtop;
“We’ll all be rooned,” said Hanrahan,
“If this rain don’t stop.”
And stop it did, in God’s good time;
And spring came in to fold
A mantle o’er the hills sublime
Of green and pink and gold.
And days went by on dancing feet,
With harvest-hopes immense,
And laughing eyes beheld the wheat
Nid-nodding o’er the fence.
And, oh, the smiles on every face,
As happy lad and lass
Through grass knee-deep on Casey’s place
Went riding down to Mass.
While round the church in clothes genteel
Discoursed the men of mark,
And each man squatted on his heel,
And chewed his piece of bark.
“There’ll be bush-fires for sure, me man,
There will, without a doubt;
We’ll all be rooned,” said Hanrahan,
“Before the year is out.”

I would not trust the CFS beyond the next month or so. I’ve done so before, and it has made an a– of me.
There was a long La Nina from March 1954 to January 1957 which can be called a “triple dipper.” El Ninos were few and far between back in those days. If we are returning to that part of a “cycle,” it will be hard to keep world temperatures from dropping.

Well now these ensemble forecasts have been off the chart for a few weeks now, nothing new. And they’re all wrong. They all show a swing back up towards positive territory in March. The Nino 3.4 just doesn’t do that.
I said on a couple of accasions earlier this year that a La Nina will develop if the 3.4 doesn’t swing back up by the 2nd week of July. It didn’t and a weak La Nina started to develop.
The 3.4 chart will stay on this path until early January, that’s when we’ll know if it will swing back up towards neutral. (And it should)
The difference between this La Nina and the one of last year is that this one is NOT accompanied by strong easterly trade winds.
http://www.pmel.noaa.gov/tao/jsdisplay/plots/gif/sst_wind_anom_5day_jsd.gif
(Notice how the cool Pacific waters are broken up somewhat. That’s because the winds are in all sorts of weird directions.)
http://www.osdpd.noaa.gov/data/sst/anomaly/anomnight.current.small.gif
The Southern Oscillation Index (SOI) has only recently barely hit La Nina territory due to the cooler than normal SSTs near Darwin. These SSTs have recently been warming. If they continue to warm, the SOI will climb dramatically, the trade winds will pick up, then we might see this La Nina develop into a strong one. (I’m betting the 3.4 will barely hit -1.5 i.e. not as strong as the 2008 event)
The upshot of it all is that this La Nina (whether moderate or strong) will be with us until the years end, meaning we will have cooler than normal temperatures right the way through until at least next July/August.
In the meantime, check out the amount of radiation that’s been leaving the system for the last 4 years or so

*EVERYBODY PLEASE CALM DOWN BEFORE WE ALL MAKE FOOLS OF OURSELVES IN PUBLIC*. There are *TWO* sets of forecasts accessable from http://www.cpc.ncep.noaa.gov/products/people/wwang/cfs_fcst/ There is a “raw” forecast, and there is a “PDF-corrected” forecaste (PDF = Probability Density Function). See http://www.cpc.ncep.noaa.gov/products/people/wwang/cfs_fcst/PDFcorrection.html for an explanation…
> The probability density function (PDF) correction is done by mapping CFS
> forecast PDF to observed PDF. The observed PDF is defined using OIv2
> analysis for 1981-2006. The CFS PDF is defined using individual members
> (15 for each initial month) from the hindcast for 1981-2006. The PDF mapping
> is a function of initial time and target time, and is done for monthly mean and
> for individual members
In plain English… the raw forecasts tend to overdo the extremes, which has everybody here fooled. The PDF-corrected forecasts tend be more accurate. The raw forecast for Nino 3.4 is at http://www.cpc.ncep.noaa.gov/products/people/wwang/cfs_fcst/images3/nino34SSTMon.gif while the PDF-corrected forecast is at http://www.cpc.ncep.noaa.gov/products/people/wwang/cfs_fcst/images3/PDFcr_nino34SSTMon.gif which shows -1.5 for January.

I live in the desert southwest where we are dependent on the watersheds of the Colorado and other rivers for our water. The very wet years of the last two winters have lead to enormous snowpacks and raised the numerous reservoirs to about normal levels after a long period of drought. All the Upper Colorado dams are full and the swing Upper Colorado reservoir Lake Powell is comfortably full and at 75%.
I remember the local CAGW nutcase saying that reservoir would become nothing but a river a few years ago, with no water in it, a victim of Global Warming. Of course a warmer World would have more evaporation, and then consequent precipitation, but the eco-nitwits are incapable of rational thought.
We still have space for water in Lake Powell and Lake Mead the swing reservoir of the Lower Colorado is now over 50% full too, but it could still use another year of great melts to fill, and it appears we will get it. Meanwhile all the other Lower Colorado reservoirs are full and the snowfields in the Rockies are already at 200% of normal depth.

Hi Walter, Sorry, no one panicking here. We know that the “forecasts” are mostly bunk, and only tend to follow the current trend before rolling the dice and predicting the bottom. (Or the top.) I think the only real new thing that we are seeing is agreement between the models. Usually they spread out and all options are open after about six months or so… I always thought this was so that the “experts” could claim that their forecasts were robust, as it was predicted. (Not mentioning that EVERYTHING was predicted.) I have been watching the model runs for years and I cannot recall them ever “agreeing” to this degree. Interesting…

I’ve noticed the same thing in southern New Hampshire. Usually this is the peak of Sugar Maple glory, but the leaves are mostly gone, with the seeds remaining. My guess is that, although Irene did not take many big trees down, two periods of thirty-mile-an-hour winds on either side of the weakened center, (which was a let-down,) did tatter the leaves, and left them bruised and wide open for various fungus infections. They seemed to just brown and dry out and fall off the more exposed trees. Down in the low-lands the swamp maples were more protected, and glorious as usual, around a two weeks ago. Despite the mild fall they seemed to change at the usual date, which tends to suggest to me that those trees shut down due to reduced daylight, rather than temperature.
By the way, swamp maples shed their winged seeds in mid summer. Sugar maples shed theirs around now, but usually you don’t notice because the leaves are still on. I agree it does look bizarre to see a maple with no leaves, and all those seeds.
We can call it, “The Autumn of the Seedy Maples.” It has a certain ring to it.
Ask old-timers in your area if they’ve ever seen it before. Even if it isn’t a sign of what sort of winter will follow, you may get a good story.
One old-timer told me of a circa-1940 late summer hurricane which blew all the leaves off a lilac hedge. Because the weather was still warm, the lilacs grew new leaves, complete
with the next spring’s flowers! He said it was strange to see lilacs blooming in September.

I’ve been thinking the same thing. However I’m also curious about how much water in in the icecap atop Katla, in Iceland. If that volcano blows all that ice will melt very quickly. I wonder if it is enough to make a blip in sea-levels.
If Katla swiftly dumps a vast amount of fresh water into the Atlantic, I expect the gulf stream will be split. One half will head back to New Hampshire, and I’ll be able to plant peaches and palms. The other half will head to Morroco and the Sahara will become a verdent pasture. Meanwhile European scientists will give up on windmills, and will focus on genetic reserch and on bringing back herds of Wooly Mammoths…. /sarc

The cooling atlantic is not the end of the overall warm amo, but is in line with what started happening in the 1950s, as is the PDO.
60 years has been the length of the first cycles measured by thermometers. No reason to think this one will be any different. Unless of course you are Hansen/Gore/Mann, seeking millions in return for predictions of linear/exponential climate doom. Everything else in nature moves in cycles, so why expect climate to be any different? We’ve just had 30 years of hot, now we are going to get 30 of cold.

Fascinating. A double dip, but not sure what it means in terms of weather. Last year at this time the La Nina was being blamed for effectively zero rain in Western Australia, but this year we have had pretty much average rain so things are not exactly the same. I wouldn’t bet that anything will be the same as last year so really just wait, see and be prepared.

If we are lucky, the warm pool just off the coast of Washington and Oregon will add moisture to cold air and bring mountain snow. If that same warm pool (left over El Nino’s) eventually cools and we get hit with another moderate La Nina next winter, we will have bitter cold and dry winters here. Rivers will freeze from the bottom up. Wheat will suffer. And a dust bowl will come round again as this cold dry air makes its way over the Rockies and across the corn belt.

Is there an effect on equatorial trade winds of the change you describe to the jets, toward meridional and equatorward direction in response to weakened solar output?
An effect on trade winds might help explain an effect of solar phase on which way the ENSO leans.

October 17, 2011 9:33 pm

The AAO is also predicted to go further positive which will force on the deepening of La Nina. Current solar EUV values are still low, so the predicted massive winter for the northern hemisphere is taking shape.

double posting;Watch what happens when we have a Synod conjunction with Jupiter on 10-29-2011 when the moon is maximum south declination. There should be a larger than usual meridional surge of warm moisture coming off of the equator into the mid-latitudes having some intense interaction with the Mobil Polar Highs that will be forming the other half of the lunar tidal bulges in both hemispheres.
These patterns are what got me interested in wanting to understand WTF was going on, back in 1983.

Then you have Hengill, atop a triple junction, that some company thinks its a good idea to hyrdrofrack with a mix of CO2 and H2S. This thing has been sporadically swarming even after the pumps are shut down in the wee hours on the weekend… all by itself.
Add to that the ever popping volcanoes on the Kamchatka peninsula, Japan’s active eruptions, and the El Hierro in the Canaries… the eruption that can’t make up its mind. (Its started enough to cause them to evacuate La Restinga)

Last week, the Nino 3.4 index was -0.77C.
Usually, a large La Nina or El Nino would be more extreme at this point of the year, mid-October. There is a definitive seasonal cycle to the ENSO where it builds in the summer/fall and peaks from November to February with December being the most common peak for events.
The 2010 La Nina had already gotten to -1.8C at times last October.
Global SSTs, however, have fallen quite a bit over the last year – down to 0.07C last week. Going back 30 years, Global Ocean SSTs have not really changed very much. The AMO looks like it is falling now as well after rising throughout 2011 to date – it seems to lag behind the ENSO by about 8 months.

October 18, 2011 10:58 pm

As Joe Bastardi already said earlier, the NCEP forecast is a joke. Even the new CFS v2 forecast is forecasting a super La Niña that isn’t going to happen. Instead, as Joe said, we’ll likely see a strong cooling of the oceans globally while the La Niña remains in moderate territory. Also, remember that a La Niña does not mean a cold winter across the eastern U.S. or even across western Europe. Most La Niñas help develop a positive AO and NAO and a negative Pacific-North American Pattern. This puts the trough in the western U.S. with a ridge over the Southeast. Warm air is pumped northeastward from Mexico and the Gulf into the eastern U.S. This brings heavy rains/storms into the Ohio Valley while leaving the SE Atlantic coast and Gulf Coast dry as a bone. Look at La Niña winters like the ’73-’76 super Niña years or ’88-89 or ’98/99 and 99/00′ which were two of the warmest winters on record in the U.S. In fact, a repeat of 1999/2000, which has shown up in the analogs, would mean a blowtorch winter for the entire U.S. outside of the extreme west coast. It would also be dry with little snow for anybody as well. I don’t think that will happen though. 1999/2000 saw very anomalous stratospheric wind patterns that kept any cold air from reaching the mid-latitudes. Expect this La Niña to bring a month or so of nice, cold, wintry weather for the east and south… but then expect the majority of winter to be mild on the east coast. Spring is another story though…

I don’t think we can rely on past weather patterns to predict the upcoming weather events. Even Joe has been caught out on this one along with many others of high standing. The low solar EUV and changing jet streams are throwing another important factor into the mix that we have not seen before.

I agree.
I have notice the wind and weather no longer come out of the west south west as was typical in the last fifteen years. Now I see weather move in from the west, north and south as like as not thanks to the “Loopy” jet stream.
Makes figuring out what the local weather is going to do a real royal pain in the neck.

I maybe the only person posting from the southwest. All you folks just complaining about cold. How about servere cold snaps(-30deg all the way down into Mexico last Feb) along with drought compounded upon dorught compounded upon drought! I hope this model is flawed! If its solid, it means NM and TX will basically become inhabitable in a about a year, two years tops! The rest of the south east of Texas probably will fall into drought as well! The southern farm and ranch land will dry up, while northern farmland floods-this spells disaster for American food independance! Uhm,yeh, my guess food costs will outpace inflation 6 to 1!!!
