Re: Long Range Thread 18.0

[billg315]

I guess another way to put it is, my view is that in the short-term I like to look at the models for smaller scale details. But the further out you get from the current data input, the more small errors in the modeling can compound making the small-scale "details" less reliable. However the larger scale atmospheric patterns may still be somewhat accurately reflected so they can give you hints of what may happen.

You took the words right out of my mouth Hyde!!  It was some mirage with winter being over I guess I hurt my back with that ice this morning, and the storm before you had close to 8 inches and me around 5 . you can't say winter is over in these parts until April even though this winter has been a big let down.

I couldn't agree more with Hyde and Jim. Maybe some on the coastal plain are throwing in the towel but 25 miles N&W of NYC it can snow through mid April.

8.5 inches in January and 2.9 inches so far in February isn't great and the storms have been frustrating with all the mixing. The temperatures haven't been great either although January did end up normal temp wise. If we can get from Mid February through March to cooperate this winter could still get a C+ here, right now it's a D.

Where I live its an F. I currently have 10 inches for the season. I need another 20 just to make it to average. I'm going to need a big storm to make it happen. These minor events are not adding up enough.

And you're being generous only using 30 inches as your average. NYC's average is 31 inches the last 29 years, yours is probably more in the 35-38 range.

The guidance reliability is dog poop (including the ensembles) beyond 5 days; especially with regard to MJO projections, NAO, PNA, etc. Maybe the ensembles show you a glimpse into a pattern at 12Z, but then 0Z render something completely opposite of what is it just showed. Seen this too many times to the point where long range forecasting becomes almost impossible and maybe those gifted enough to look at observations can predict outcomes "sometimes" (guys like Isotherm).

About 1 month from now towel throwing will come from me, if we are laying an egg. Just think it's a bit too early for that right now.

[SoulSingMG]

I'd just like to remind everyone that March is in TWO WEEKS.

I am shook that we haven't had a formidable snowstorm in NYC metro since November. SHOOK.

[SENJsnowman]

Rb, my actual question was “is the new data baked into the cake” and inasmuch as it is, then my question is answered No.

So, as to these threats only, I see no reason for optimism that we will see any kind of blockbuster snowstorm thru next week. Though I would argue that 6”+ of all snow is a legit snow storm by any measure and all but the Philly-NYC corridor is progged to see that much- at least in total snowfall- over the next 10 days.

Of course, mother nature can change the track or the set up as she chooses. So, at any time she could throw us a really meaty bone in the next 3-4 weeks, including this weekend and next week. But the name of this winter, up until now at least, is Murphy's Law. And I think we’ve hit the point that this identity is forged and any contrary result would be isolated.

So, I figure we have no choice bul try to maximize what can happen here. Some modest shifts in track and temps etc can create/enhance a moderate snowfall for all, which would be better than none for sure!

But wow, when you look back on past 2 months, Murphy’s Law for sure. A partial list of what has gone wrong with the tele-connectors:

Warm waters in pacific by US, not by Asia
SSW stopped favorable pattern
MJO ruined favorable SSW
Pacific ridge over Minnesota and not Montana
Pacific ridge in a tight jackknife along I-90.

Everyone of these negatives happened when we already had a good pattern or several important pieces toward an imminently good pattern. And all of them were deal busters. We never got the right ridging, phasing or blocking, and so we have cold air suppression ots or warm cutters.

The little bit of snow we have received has come from a few well placed, but relatively weak boundary events or glancing blows of small overriding events. And even then, warm mid levels (sleet and freezing rain) and dry lower levels (dew point/virga issues) killed any real promise for those threats. To get snow this year, we’ve all had to toe the 'line' for hours on end, either to stay under radar or to stay blue, for a season high of (we need a CP button on here) 7-8" or something. (Aresian actually was higher, but I mean our lower 48).

Another way to look at it:

Just about every single decent snowstorm in the northeast has to be the sum of several moving parts, and in sequence and even at cadence within that sequence. We have not once even come close this winter. Not sure that any model has shown a coastal storm inside of even 96 hours this winter.  Lol These negatives are just insta-shutdowns. And the positives are table scraps. We're getting decimated over here.

And thanks for the encouragement rb, Frank Bill et al.

Folks,
After reading Isotherm's re-analysis of this winter makes great sense and this is something no one saw - MJO phases and convection, QBO interference at the 30mb level overwhelming the pattern and the PV Split down welling.
The atmosphere has had a 1994-95 look to it more a Nina state than a weak Nino state.
The QBO at 50MB has been N and from the data this aided in the SSW event. The strong MJO SST waters just killed us/destructively interferred with our winter pattern along with the 30MB in a westerly positive flow never allowed the PV Split to totally make its way down to the troposphere or are level of weather. This was a  NINA pattern all along and hinted at moderte NINA at times with teh pattern. This curve ball just killed us not allowing the NAO or AO to go N and thus helping promote a SE ridge. The PNA was mostly N and even when we had the N EPO the cold air got blocked by the PNA or was squeezed by it. The Azores High was relentless since summer and never backed down not allowing the NAO to go fully N.

This is what he showed, look at that connection


See folks, it is not what happens in in Central Plains that affects our pattern but rather upstream in the Greenland to Europe, Arctic Circle areas, and teh greater affects are in Tropical Pacific, Indian Ocean and Tibetan Plateau/Himalaya Range. Solar had a tremendous affect on our pattern - low solar that is and it will continue for the next decade plus since we are in a Grand Solar Minimum Cycle.

Going forward the MJO is in and going into as forecasted the favorable phases of 8, 1 - 2 - 3, once this dies off then we hit Spring which should commence in about a month March 15thish.
We have a window of a few weeks opportunity to see a N NAO or Greenland Block starting next week later part IF it comes o fruition and isnt destructively interfered with as it has been all winter.

Here is the QBO chart - the red orange you see is the positive and teh blue above the 30 is Negative as referenced above


here is the link if you wish to view and learn about the QBO

https://iridl.ldeo.columbia.edu/maproom/Global/Atm_Circulation/QBO.html?T=604

So this winter parallels 1994-95, 2001-02 as per Isotherms analog and I add 2011-12. Again the variables were all there for a good to very good winter with a weak to modoki Nino shaping up, Low Solar and QBO being easterly but transitioning to westerly, storm track setting up from Fall on, very cold and snowy Canada, major hcane hit the panhandle as an analog and other variables.

This will be a great learning lesson for us all.

It came in spurts. But i didn't think the gradient with the High to the north was strong enough.

[sroc4]

There are still threats looking ahead but non of them are really evolving into a well defined event at this time. Nickle and dime crap for the most part. I’m going to remain fairly quiet in the form and focus on other things. I’ll have my ear to the ground of course but there has been some new blood posting thoughts and analysis to which I want to say bravo. Keep up the great job. I look forward to reading.

This is a totally debatable statement given that it is just a new core running the GFS's old resolution and horrible physics packages. While it was not the correct core choice, it will certainly improve NCEP's global forecast potential in the near and long-term.

Looks like the southeast ridge stay in place through the end of Feb. Almost all forecast variables point to cold air flowage returning to the east in early March. Until then, numerous SWFE for the Northeast (so crap will fall from the sky).

[amugs]

The pattern is showing a phase 7 MJO of the EURO with a robust Negative PNA. The forcing is EXACTLY where we want it to be this time of year, yes tehre is a lag of a few days but unless the model start to show the correlation to this phase then we lose more winter time.






To much trough in the west - it should be centered over the NE not the WC in this phase




This is the latest time frame you woudl see correction in the models to the MJO phase 8.



Not just yet I need until this weekend (Sunday) to see if it comes aorund to the MJO phases if not I'm out till....................

Yeah, but without the great man's death/ sacrifice, we never would have Creed I and Creed II. Granted, I cried in Rocky IV as I am crying over this winter.

[Grselig]

However, this winter we have MUGS screaming in its corner, just like Angelo Dundee did ,"Your blowing it son." Look what happened.

[amugs]

Guys the towels in my hand and my arm is ready!
After reading Isotherm and know JB's latest blogs which talk about how the 30mb stratospheric level being positive westerly which blocks all the downwelling affects of the SSW from the 50mb level. This in turn pumped the convection off the African coast whichnlally gags it's way through the warm phases and was a steroid injection ton to the wave. In turn the Tropical Atlantic meaning the Azored High was being pumped by this as well. So basically we had coming and going and wereally really dead in the water. Nowe the analog shows a cold March. Go figure and I'd we get to phase one the storm track tjen is off the mod Atlantic and the retrograding Azore's high decouole's from the Greenland Block and allows it to take control again. Could be an interesting last few days of Feb, after the 23rdish  through the first two weeks of March at best.
Here are the analog maps and maps of the Tropical Atlantic showing the SE Ridge it is more of an El Nina look in phase 7

[amugs]

PS no more euro maps as per the EUROPEAN modelling center. So all we can post is American/Canadian models and only give a synopsis analysis of the model runs.

When the last towel is thrown in mostly likely a MECS hit us.

[SENJsnowman]

LOL, for the first time all winter, we may actually have a low pop of the coast right at the NC/VA border.



But don't you worry winter weather lovers, the mid levels are working hard to ensure that this system gets blown straight out to sea (in black- nice jet stream, btw!), rather than phased up the coast (in red, not that it's cold enough to snow anyway).

[skinsfan1177]

I'm on board I'm not liking anything looking forward the -pna is killing us early spring may happen.

[Snow88]

Looks like a little snow for NYC northward Monday

[dkodgis]

Snow? Go on get gone!

[Irish]

Is there any signal for a possible event for next Wednesday, the 20th?

I believe N & W of NYC will be cold enough to eke out a couple of inches, S of NYC and NYC itself probably not.
