Please ensure that the majority of your posts in this thread are model related - a theme of model discussion needs to run throughout.
Some off topic chat and reactions are ok, but please use other, more relevant threads for entirely off-topic chat (such as snow reports, met office forecasts and general chat/moans about the weather or this winter).

For more no banter and just model discussion please head to the new focused model thread - this is also a great place to post (or cross post) your longer model summaries or thoughts around the models.

Correct and it's the same at 240z BEFORE low res

Doesn't save us I'm afraid.  No low res on FV3 - high res out to day 16.

That notwithstanding, just good to see those charts at day 10-11.

For those who think the SSW was a bust take a look at this at T+3   Then look at the NW/SE jet axis over us, then look at the fact that the downwelling has been delayed but is just und

Yes Mike but let's just let the heights build and then look at where it goes.

Thanks I hadn't realised.

Hi gang ,i am around , i have been lurking ,reading all the posts etc .well in my book still time for snowfalls and plenty of action weather .Just a thought but could we see Erik this weekend ,i had an uncle  eric .? . Thanks to all the posters who keep this forum alive ,Best forum around .cheers gang  ,sausage sandwiches brown sauce and a STElla to all the Cold Hunters .

Yesterday’s T168 and today’s T144 . Definitely gone the wrong way . I thought the ecm was king ? Have no confidence in it at all anymore after this winter .

You've got to bear in mind that the overall pattern is much the same. Compare the 500 heights and you will note that the wave pattern is fairly close between the two. At a more local scale, the small differences in the 500 pattern mean fairly large changes locally at the surface. So, it may seem that the model is jumping around a lot, but on this SE two charts they are fairly consistent.

Here we go again, it's all over based on these few runs, yesterday it was all on, history tells us nothing, like I pointed out earlier models are struggling big time. The funny thing is if the models show much better runs tomorrow will it be game on again. I fail to see how models at day 10 and beyond spell game over. 

but it’s at the more reliable  timeframe at t120  it’s gone flatter not day 10 ,and has been pointed out by others it’s rare the models revert back to a colder outlook again at that timeframe.

Perhaps, but look back over the days on here, one day the cold is being played up, the next it's being played down, the met are still giving us a signal on much colder weather final third of this month. And any experienced forecaster will always tell you its a mistake to over analize every single model run

Today's GFS RMM plot gone a bit berserk with the MJO amplitude through phase 8, but the 12z GFS operational running with MJO P6-8 in February reanalysis composite script of heights building N over UK (phase 6), then Scandi ridge building (phase 7) then retrogression of ridge toward Greenland (phase 8 )

210834156_diagram_40days_forecast_GEFS_member(1).thumb.gif.d221bd91b03abf4d2ad4828965569d79.gif

The GFS was suggesting zonal winds in the upper stratosphere pushing down and coupling with troposphere later this month, but that seems to have disappeared on today's NAM plot with the easterly winds still dripping down through the troposphere after 20/02.

gfs_nh-namindex_20190207.thumb.png.c2ea33b7ccd07c9a876c16ff1f36d2b6.png

So perhaps we have not seen the back of the SSW reversal impacting the troposphere and indeed it may continue to impact on tropospheric circulations for a while in conjunction with the MJO colder phase wave amplification and retrogression.

Some similarities since beginning of the year to perhaps Jan/Feb 2013 following the SSW in early Jan that year, in 2013 there were bouts of cold, though not prolonged, with some milder episodes, it took 2 months for the full effects of the SSW to impact Europe with deep cold from the east - which resulted in an historically cold March. Cold may come sooner this time, but perhaps not on the severity of March 2018 or March 2013.

Excellent post as usual.

Totally agree it's been a very slow response with the 30hpa stratosphere to respond but backed by the right background signals to especially the el nino flat line state and the low solar activity I agree thanks enjoy reading your post.

think it’s just frustration ,feels like we have been chasing a decent easterly since end of November ,that one back end of November was only one ,so far that delivered snow for about an hour before it melted ?

I'd ignore the ECM tonight the switch around is way to dramatic beyond 144hrs stick to the ukmo until the ECM picks up on a different signal.

But the signs are there and models are going to chop and change alot in 24hrs when you see a few days of consistent modelling then yes maybe get excited but I've to got sucked in by model run hysteria as well.

with Greenland blocking being my worst enemy with the models.

But I reckon we are close to a 2013 the closest since then.

It's been a chaotic winter and a nightmare to forecast.

But in my opinion it's not over yet.

Give it a couple of weeks then yes I see you next winter lol.

The ECM still a good run but it’s a slow burner , it’s heading towards some of the gfs op FI runs so that’s good . Was just hoping we could of got there quicker . Just prey we do get there in the end otherwise it’s gonna be the final big kick in the nuts . Ouch ?

The negative comments in here are  exhausting and wearing my soul away. THIS IS A “Hunt for Cold” thread please please please I plea to you, if you can’t find any cold then don’t post. I can’t be the only one who doesn’t want read about south westerly winds in here or all of the other guff being written All day today it’s felt like I’ve read about flat pancakes and lack of amplified ridges. Surly all of that can go in the other thread. 

? feast your eyes on the GFS Control young man

There's definitely the potential for something wintery towards the last 3rd of February.  

As usual with our island, the building blocks need to be perfect for deep cold but at least we're in the game. Worst case scenario, we can all start thinking about some spring warmth soon anyway!

They are comments on what the models are showing at the particular time on that particular run in comparison to previous runs. Nobody is lying or being deceptive.

Mate, it's rude to comment on the model output in the model thread when its not showing cold, you ok with that?

If you don't like the UK model output on a UK weather forum, maybe you could discuss the cold pool over Siberia instead? Even though few people live there?

In all seriousness, yes it's the hunt for cold thread but its still model output discussion as well. If its just 'cold charts' then we may as well take a black and white map of the UK and paint a blue colour palette over it.
