UKV is worth a quick look this evening. Precip from about here

It finds another pool of cold uppers early next week.

I was just looking at the 12z and 18z and was thinking where was that block to the NE and ,looked at weather over NE America and realise the reason why the models have trended milder and unsettled in latter stages of FI - because it's got colder in USA/NE Canada/eastern seaboard and this has blasted up the jet yet again.

The increase again in GEFS scatter paints the picture this morning. Will it be a Valentines Day massacre or will the NWP spread the love? The macro-pattern into next week is still uncertain.

JMA also excellent, as is ECM in far FI (see wxcharts)

Also I should add that the KMA picked up on this yesterday in the 12zs. So the south korean model may know something the others don't!

I'd agree with the GEM and UKMO set up though, both look good for cold longer term.

All in all I'd say a tweak back to a milder 850 interlude in the short term (boooo!) but then we do import another short lived cold pool for a day or so. Post that the majority option still looks like the atlantic having enough grunt to keep HP from doing anything interesting over the UK. There remains a realistic chance though of the HP being more dominant and if I squint I'd say maybe that option is a touch more likely this morning than yesterday, albeit from a low starting point.

Re Brian's UKMO precip comment, I've kind of accepted this is all just the wrong side of marginal at the moment, with each cold pool just not being deep enough and/or too much mixing with slightly less cold air etc. I assume the snow shown further west reflects higher ground, which seems a fair bet to me although I'm still a touch surprised that say the Downs don't have a little snow shading down here.  The UKMO run is nice because of the potential at T168 rather than the near term stuff IMO (unless you're at height in Wales I guess!) - it's tantalisingly close to getting a proper deep fetch easterly albeit would need the decaying HP ridge over eastern Europe to clear out first.

WX temps: in week 1 near norm in W Europe , much above in the east though this still leaves that area below freezing. In week 2 some very much colder air appears near the Urals,even some in Finland, but not getting further east. Atlantic countries (Spain, France, Britain) mild. Pptn in week 1 in the Med, Europe dry; in week 2 some rain working in across Atlantic coastal countries.

GFS Op 00z: current HP moves across to the Baltic and stays there until Sun 16th, generating a flow between E-ly and S-ly for W Europe including Britain. There are small cold pools in this flow but nothing really cold as the origin of the air is the E Mediterranean. The Atlantic starts pushing in 985mb Tue 18th N Ireland and 1000mb N England Sat 22nd, but bringing air from the N Atlantic with Britain on the wring side of the 850hPa line, so expect cold rain.

ECM: resembles GFS

GEM: has a more extensive cold pool from midweek Wed 12th, and then activates the Atlantic a couple of days earlier, but with LP 985mb heading further S, to Portugal Sat 15th, thus a stronger E-ly for Britain.

GEFS: In the S, more unsettled than shown yesterday, with small amounts of rain (low chance of snow earlier, heavier rain in SW later,) on and off for the next two weeks; In the N mainly dry for the first week, possible snow flurries, then small amounts of rain.  Temps generally cool or cold until Wed 13th then the mean with majority of ens members near norm, just the control and a couple of followers offering something cold from Tue 18th.

I confess from an IMBY point of view I’m only interested in what might happen later next week as damp sleet doesn’t do it for me.

GFS still not too keen on allowing the proper cold air in from the east but it’s fairly close and some of the suite again look decent. The fact that GEM does the business this morning isn’t too convincing because, well, it’s GEM. UKMO however is pretty impressive to +168 and that is more attractive to me.

There’s more to come from this latest chapter of chase the easterly.

Still feels like cherry picking at best, as the output for memorable cold dissolves day by day. 

One good thing with this easterly waft, before the grey duvet is drawn across the UK, is that Continental air will aid with drying the ground up quicker with any brighter days.

The parks, gardens and local woodland trails here are an absolute quagmire.

Ecm 06z has followed the ukmo model. Only goes out to t144 but looks would expect a very much colder pattern to follow on from there. A big wave two event is under way at the moment, larger in fact than the wave that has brought the ridging to enable this continental flow. Will be expecting to see some potent wintry charts in the coming days. Time frame for a real taste of winter 14 of Feb and there after.

If people are talking about the Met Office Global deterministic the obvious thing to do is compare it with MOGREPS-G which is the same model.

Luckily the other models are not quite so bollox.
