Real snowfest from Wed 7th onwards.

But I'm not sur I believe it as the snow comes in from the NW - a few days ago the same forecaster brought the snow in from the E!

Typical dross this coming week with limited sunshine, rain, drizzle, wind, showers and some mist/fog.


Any wintry stuff, as always, most likely in the N and on higher ground at that.


An E'ly at some point?


Never on the cards IMO. There are always some rogue runs within GEFS but as we head into February, it is very much a case of looking W and NW for our weather.

The EPS this morning retains its easterly cluster. Indeed, the control run has a long-lasting easterly flow...


 


...for the Netherlands, as it turns out. Here it's a weaker affair, but the -10C 850 line does affect the UK for a bit.

A Spanish plume in the summer is far far more likely then a cold easterly in winter. Sure it' the model output and all model output is fair game, but with the just sniffs of one I can't figure why some repeatedly get the hopes up. 


With regards to Mr Murr it was not my intent to be disrespectful towards him. Over the many years I've been following this forum I can say with honesty personally speaking from memory (which can be foggy) I can't remember seeing a cold spell come off after he posts his very technically loaded posts... it' almost like he's an omen when it comes to cold spell - superstion an all.

Incisive as always...Steve has forgotten more about model watching in a day than you'll know in a lifetime.


 


 


"Hopeful" describes your opinion on certain posters, and it does not accurately reflect the balanced opinion on model output that is occurring in this thread IMO.

Looking ahead at the possibilities on this occasion I think it will be a case of how far West we can back the set-up, overall factors look to favour Scandinavian blocking certainly more towards mid Feb


From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.

Hah, looks like my comments about the EPS control can be discarded... for whatever reason, weather.us was serving up a mixture of last night's 12z and this morning's 0z. The control this morning is a textbook easterly setup, with sub -10C 850 air covering the majority of the UK from the east and widespread snow as a result.

I think at the very least we can pin a date as a ‘trigger’ point when the easterly may or may not evolve - and that’s the ‘third’ transit low moving across on the 4th Feb. Dive SE, raise heights enough behind it, allow a sufficient break before the next break off of energy from the west and bingo. No proper ridging and WAA behind this low and bust.


Its a very simple description but the date is now coming onto the sub 180hr page.

Things developing pretty much as expected. As you get to within 5-6 days of February 6th, expect a zonal picture with west to east movement.  The GEFS have picked up on this now and are eliminating the easterlies for February 6th, one by one.

I guess we'll find out


Objectively there's no doubt the 00z has watered things down this morning and is showing a fairly standard 'pressure tries to build, Atlantic shoves it away from anywhere interesting' scenario. There is enough cold air floating around to mean it gets dragged over us at times so it's not an overtly warm run, just not an overtly cold one either.


ECM this morning is nicely poised with chilly/cold air over the UK and some proper cold just to our east but also a big chunk of the PV over N.America/Canada migrating over Greenland, set to dump cold air in to the Atlantic and give the jet a kick. Personally I don't think this precludes an Easterly as the key thing will be how far the PV lobe moves East and the angle etc. of the jet. 


All good clean model watching fun - it's surely still better than a screaming zonal pattern and looking at T384 for a slightly longer lasting lee northerly

SO not only was the easterly a no go but the dry spell is a no go' as well?

More dross to get through next week, an easterly afterwards? I’m not at all convinced, “winter” can’t end soon enough for me.

It's always been positive AO all winter. I don't know why the models are flipping back to a very unsettled first 2nd week of Feb. unless this is a temporary blip!?

A quick look at the model output this morning makes me think the most likely scenerio is a series of NW outbreaks bringing wintry showers to the north , followed by a ridge bringing some settled weather followed by a brief spell of milder weather. Then repeat. Seems a small chance that around 6th Feb instead of the milder air toppling in from the west, the block will hold firm introducing some continental air.

Any snow was transient and just over higher ground but the south never even saw a flake and very unlikely will do. Even winters like 2013/14 or 14/15 as well as 15/16 didn't really see lying snow or wet snow to lower ground but at the very least we did have some severe frosts to make up for it - last year we saw lows of -3 to -5c in the south one night in December, Jan and 10th Feb if I recall. We just can't get any cold frosty nights this winter let alone sustained colder spell with snow.


Sorry should be in rant thread !

Yet again - HP building over Alaska and NW Canada and pushes the LOW pressure systems towards north America and gives them colder weather and pushes the PV into Greenland which then squashes/flatterns the Scandi block to our east thus, ruin our chances of any prolonged cold spell, but yet still gives N. America esp the central south and eastern coast a cold wintry spell of weather whilst we miss out yet again!!!!!!!

I think the same rule that has applied for much of this winter wrt the model output still applies now, which is that anything for more than 6-7 days ahead should be taken with rather a large dose of salt. The way I'm looking at things right now, it seems that almost anything could happen from next weekend going forward as the models seem to be all over the place as far as I can see.

Having said that, GFS was showing a cold interlude for next weekend but not with any consistency even of the broad pattern.


It’s still a case of watching the jetstream; that will determine whether an easterly is possible.  At the moment the twin themes of proximity of high pressure to our south-west and energy in the northern arm still look to be the threat to any cold spell (as opposed to a 24-48 hr cold snap).
