Is it just me or do others feel a bit underwhelmed by the effects of the SSW. In any winter we would expect the chances of cold zonality and small wedges of HP to our NW allowing for southerly tracking lows. I was hoping for some proper blocking over Greenland ...perhaps in feb lol. 

Would highly recommend reading Nick F’s post on the previous page. Will give us all some perspective.

4/1 shot then BA. Don’t think you’ll be backing that horse! 

In my simple little mind here’s how things are happening in relation to the SSW. 

1st SSWE has put the PV on the canvas and the ref has stopped the fight!

2nd Warming event has gone MMA on his ass and is going to retire him!

We will benefit imho because of the second warming event, hence last third of Jan. this however doesn’t rule out cold shots between now and then. 

I am absolutely happy for anyone to educate me if I’m wrong! I love to learn! 

From where I’m sitting, nothing’s changed!

Please now carry on with technical discussion

Quite, Blue doesn't sound as enthusiastic as last evening ..

I'm still optimistic but i would be lying if i didnt say we are fast approaching crunch time for mid Jan insofar as concrete signs of that horrid low anomaly to the NW 'doing one', so to speak..

Crucial couple of days incoming..

nope - nothing really changed ....the transition from cool zonal to cold troughy looks a little less cold this morning and the ec strat looks a little different but steady as she goes remains the outlook .....

This forum sure loves it's metaphors *see above* and they drive me nuts, mind you when in Rome.... so here goes.

We have our hole cards, just waiting for the flop.

Och well. After a few days' teasing, the GFS seems to have finally given-in to its all-pervasive eastward bias, and reduced mid-week's snow chances down to almost nothing...What will the weather do, though?

[Timmytour]

Waking up to a sense of pessimism on the forum after what seemed to be a day of growing optimism yesterday.

To be honest last winter was all about one week in late Feb really and the four previous winters were terrible! Yet on every single one of them there were times of growing excitement (in early December last winter) where trends or background signals were pointing towards winter scenes of wonder.

My feeling for this reason is that I should constantly remind myself that heights of optimism in here are frequently only topplers and no more than a 30% chance should ever be attributed to success in verification.

Just so hard to get the right synoptics to fall into place for us, but I can't live without the hope and the knowledge that the bullseye will be all the sweeter for it!

I remain eternally grateful to those on here who keep providing me with that hope, as well as the ones who warn of the dangers to promised winter nirvanas!

C'mon Winter 2018/19... we can still do this!!

The 06z is another poor run with the pv actually gaining strength and us stuck under Bartlett type weather for what seems like an eternity.

Worth keeping in mind the pro's did say that the Atlantic would rev up before any blocking came to the fore. With such favourable background conditions the charts spewed out are very disappointing 

[northwestsnow]

6Z looking better to me at 192..

Hopefully a cleaner ridge in the North Atlantic..

 

[shaky]

And once again nothing to get excited about on the 06z!!total garbage being spewed out considering what is going on high above!!dunno how many days ive gone without sunshine or a frost here now!!there is literally nothing to say about this winter!!last winter was the winter of sliders!this winter is the winter of boredom and time is ticking away fast!!

Yup and as they come closer they will all just flatten out!!its been the story of the winter so far no matter what the ensembles show in fi!!its ridiculous!!

I don't think there has really been a signal for snow pre-SSW or immediately after, looking in depth at the drivers, I admire your enthusiasm to put a dampener on the outlook despite the overwhelming pointers from the likely impacts                                      

So although the charts look crap atm, due to the background signal explained above, we should hopefully see the models pick up on better patterns for sustained cold and snow potential for us in week or so as impacts of SSW, MJO colder phases, +AAM/EAMT work through.

 

Exactly Nick. A brief period of a more mobile Atlantic squashing any Amplification attempts is what should be expected for the time being upto day 10. There should be more significant movements to better FI blocking scenarios which should increasingly improve as we go through next week. I’m looking forward to it - next two weeks should be a fun time to model watch.

I've gone about 10 days now without any sunshine here in West Birmingham. This time of year is hard enough with the short daylight hours, but factoring in endless grey skies - it's almost unbearable. 

The models are boring, there might be some interest in the ensembles but it really is look drab for the time being.

Morning run from GEOS looking at D10 across the levels. Top Down view L-R. I am liking that 30hPa view. Not much left in the Greenland sector there and hopefully the Siberian vortex will act as an attractor for the other remnant filaments.

[Jason74]

As always, patience is the key. Pay attention to what posters such as GP, Chio, and Nick are saying. Repeatedly. 

[sunnijim]

In recent years there seems to have been a much greater understanding of warming events and their scope for impacts on climate.

However, when an event is in the pipeline rightly or wrongly I garner that many people ( tabloid journalists,many weather enthusiasts here and elsewhere) assume it means this little island of ours will be plunged into a colder spell at the very least.

We know things played out in our favour at the end of February 2018, however I can think of a few warming events that have not delivered to our tiny island in recent years.

Could there be Weather forum members in places like Denmark right now that are using the same evidence we have at our disposal to think this current cycle of warming ' is further down the line'  than many people keen on an arctic incursion for the UK would hope,as  areas just to our East and South are plunged into the depths of winter?

In short, are the effects of this most recent SSW well under way at 'ground level' in areas very close to home on a global scale?

Does an SSW weather event really mean that HP will definatly set up shop in a position to favour the UK for snow?

I just feel it has to be made clear,SSW does not garuntee cold/ snow for our island, although does increase the possibility.

[Weathizard]

I wonder what’s happened for the sudden strengthening of the vortex, this is is at day 10, judging by the latest runs the best we can possibly hope for is cold mobility.

Yes , better GFS 6z...

Cold zonal ..

[mulzy]

GFS day 12 - looks zonal but there is a significant wedge there...

Yup last year already by now i had a couple of meaning full snowfalls!!and thats with background signals know where near as good as what they are now!!this year its hard to even get a frost lol!!

Possible scandy high gap appearing 

[Leo97t]

Seems like the better the background signals getter the stronger the polar vortex gets. If the output is anything close to right, anywhere apart from northern hills isn't getting snow until February. It looked so good a couple days ago...

[northwestsnow]

Beautiful..

Glad someone is watching .......wedges everyone .....not sustained HLB - wedges....... also more likely to deliver snowfall, especially given the general guidance ......if we are going to get to a wintry destination late jan then at least let’s try and get there with some decent wintryness in the transition .....

again, a gfs 06z op which is a very decent stab at where the ens guidance has us through week 2 ....what it does day 14/16 is anyone’s guess !

Yes - everything unfolding exactly as expected, just a little later, cold zonal leading to Greenland heights leading to Scandi high early feb always has been my expectation, unless there has been a massive downgrade in the eps, everything looking the same as yesterday, cracking GEFS suite and this GFS 6z op looks conducive to big snow events at the end.
