Is there a late Beast from the east on the way: The GFS Op 0Z says so, with widespread transitory spring snow-fall. Here’s a link to the pressure chart sequence. If only this were a month sooner!!

WX charts keeping freezing weather across Scandinavia and most of Russia for both weeks but in week 2 there is an outflow of colder weather (though not freezing) across Europe north of the Alps including Britain. For spring warmth go to the shores of the Caspian. Rain in week 1 for S Britain, France, Spain and Italy, moving a little further S in week 2 and becoming heavy in most places for the Alps.

GFS Op - current LP becoming centred over Britain and not filling until Monday. New trough reaching N Ireland from the NW 985mb Tue 6th before retreating W-wards and setting up a situation with LP W of Ireland and HP Norway with these two systems rotating clockwise around each other so by Fri 8th HP 1030mb Iceland and LP 995mb Biscay with rather cold E-lies for Britain* persisting to Fri 5th when there is a general rise of pressure over Britain and W Europe.

ECM - similar to GFS; the HP rather more intense and the wind more SE-ly than E-ly

GEFS - mean temp mostly near norm, slightly cooler earlier, slightly warmer later, with ensemble agreement breaking down from Fri 8th (op v. cold Sun 10th, then persisting esp in the N, control v. mild Tue 12th). Rain persistent but randomly distributed throughout, only really heavy in the SW

* 6 weeks too late!

Hoping we don’t get a BFTE on Wednesday, as we’re flying from Birmingham to Singapore.  I remember the BFTE on 1st March 2018 very well, as our flight from Birmingham to India was delayed. 🙄

I think the general lack of interest in what in early Feb would be decent enough synoptics is understandable.
It really would take something special indeed to get sub -10s to our shores on an easterly in mid-March (has happened, but it's very rare).
But then again any snowfall down here at any time of the year is very rare these days so you can't be picky.

WX charts keeping freezing weather from Norway and N Baltic E-wards into Russia for both weeks; by comparison with yesterday less outflow to keep Europe cool, that below 4C mostly associated with mountains and high level areas. Rain in week 1 for Britain, France, Spain and the northern fringe of the Med; in week 2 rain retreats from Britain and a very dry area develops for Europe north of the Alps, just about reaching eastern Britain.

GFS Op - current LP hangs around for the weekend and is reinforced by a trough from the Atlantic on Monday. From Wed 6th HP develops 1030mb N Norway while the trough on the Atlantic slides SE-wards to Spain. The HP and the trough (becoming a defined LP) stay more or less in these positions for a week with winds going round from SE to E. From Thu 14th the HP develops as a ridge from Norway to N Sea to Spain with LP held on the Atlantic and S-lies for Britain.

ECM - similar but the 'defined LP' is deeper and closer (990mb touching Cornwall from Sun 10th) with stronger and colder SE-lies

GEFS - mean temp close to norm throughout,  with quite good agreement until Sun 10th, but always with a distinct group of much colder ens members including the control run from the 10th. Small amounts of pptn from time to time in different runs. Less agreement on temps in Scotland with a larger number of cooler options leading to moderate chance of snow there, but not in quantity; much more rain for the SW.

Surprised how quiet it is on here considering the latest output from most of the 12z models.

This Winter Dec Jan Feb that has gone by had so many multiple times with UKMO and GFS showing Cold Beast from the East winds, but the GFS and ECMWF often did not support it and on Thursday 29th Feb. and on Saturday 2nd March The 12z UKMO showed Beast from the East for March 7th and 8th.  On Gavs Weather Vids Model Forecast Discussions they appreciate my posts but Gavin has given me a separate section called daily model runs.  The previous round of getting me excited with UKMO showing heavy Snow very Cold was for 11th to 12th February 2024, but that was also changed to Milder weather with mixed weather regime taking over.  Western Southwest Central Europe today’s 12z ECMWF run showed the SE E tracking Low quite a deep large Low that also extends across much of North Atlantic Sea.  I hope everyone on here is doing ok.

Reminder Klaxon, Major SSW dip in PV winds on 7th and 8th March 2024.

Edit: A special long time Hi to Brian Gaze City Andy NSRobins DEW Doctormog Beast From The East and SevenDust etc!,👍😀🥶❄️.
Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.

The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge. 

With this warmth and heat, the Central and South UK has become mostly free of snow and frost.

I think this last SSW will deliver from the resultant Scandi high being consistently modelled now across the models, but the exact orientation and alignment as it wobbles about is still to be nailed. The GFS 18z Op and ECM have this aligned at +240 ish for sub -10 Hpa air reaching Blighty. It’s no unknown.

Not a great deal of change for Britain in WX temp charts for the net two weeks, but in Europe a retreat of freezing weather from most of the Baltic in week 2, while the area down towards the Danube Basin *which has been unusually mild) gets colder. Some very warm weather showing up on the southern fringes of the map (Morocco, Syria) while the sea east of Iceland is colder. Rain through France, Spain and along the northern fringes of the Mediterranean in week 1, decreasing in week 2; Britain fairly dry but not quite as marked as yesterday.

GFS Op - LP now over Britain filling to be replaced by a series of troughs working their way past the SW into Biscay . 985mb Tue 5th Fastnet, and again 975mb Fri 8th, the latter working its way down into France turning the winds from SE or S earlier in the week into a full E-ly by Mon 11th. HP then develops 1030mb covering most of Britain until Sat 16th cutting off the E-ly, but drifting S and fading by Tue 19th with zonal flow and LP approaching NW Scotland.

ECM concurs

GEFS - mean temps near norm through the next fortnight but with steadily increasing spread of ens members (op has a rather cold few days around the 12th). Rain in some ens members now and then throughout though op and control rather dry; small amounts generally but heavy at times in W especially SW.

First post for a while. Sitting back waiting to see if a worthwhile east, north easterly feed is going to affect the UK and still none the wiser. Made the mistake this morning of viewing the 0z Icon run first and thought we were in for a day of upgrades for cold wintry outlook. The 12z ecm det shows what still could be possible although the run implodes towards the end. Having said that how often if ever do the ecm t216 - t240 charts come off. 
Worth giving it another 3 to 4 days I think to see if we can squeeze something memorable out of this strat warming and reversal  for time period 10th to 20th March.  We shall see.

WX temp charts not withdrawing the freezing weather as much as shown yesterday, Still 'blue' from Norway and N Baltic eastwards through Russia, and still cool along the fringes of this including Britain. But the areas of cooler weather in continental Europe have diminished and something seriously warm is moving N from Africa to affect the N shores of the Mediterranean. Rain in week 1 for France, Spain and N Mediterranean, with Britain on the fringe of this area; in week 2 the rain moves north to affect Britain (esp W) , France and Norway. Anything really dry is week 1 and Scandinavia only as far as W Europe goes, less than previously shown.

GFS Op - LP in Atlantic spawning troughs and areas of LP pushing down towards Spain this week e.g. 995mb Galicia Fri 8th after which the area affected by LP aligns W-E across Britain 995mb Sun 10th. This main  LP then re-groups just W of Britain and associated centres run NE-wards affecting W Britain (980 mb Kerry Wed 13th, to 980 mb Hebrides; 990mb Kerry Fri 15th, 995mb Wales Mon 18th) with mostly SW-lies for the east.

ECM - introduces interval of weak HP Sun 10th (the potential trough is placed over Switzerland) before rejoining GFS with the NE-tracking LPs

GEFS - mean temps a little cooler at first and milder later but generally close to norm, good agreement from ens members to Tue 12th and not too much variation after that. A burst of rain today, then dry for a few days but most ens members showing rain at intervals after Sun 10th, for the S & W in greater amounts than yesterday, still fairly dry in N & E. .

We live in faint hope, straw in hand for the singing to start.
