EC and GFS 12z operationals were again, respective outliers of sorts. 

The mirage still flickers for mid-late Feb for something special but exists only as eye candy/ unsupported at this stage. 

Met office are now saying wet and windy is probable a week from now. Westerly dominated.

The ECM Op at 850hPa is actually supported by a decent cluster in the ensembles for 7-8 days and even beyond that isn’t without a modicum of support.  At the 2m level the Op tracks the mean for the first 8 days and is only an outlier for Days 14 and 15.

Cold GFS op run ending with a Scandi high and cold uppers with widespread ice days. Interesting for anyone looking for cold

That said, they’re a slave to the models the same as the rest of us, to some extent

Looking at the most recent ECM ensemble and the 12z GEFS set it seems to me that there are basically two means after the 13th. One going down to -10C (est mean) and the other to 0C ( est mean). The milder set look more closely packed early on the GFS but then later the very cold group shows less standard deviation. It is the other way round with ECM with the earlier cold having less sd than the later one!

So it really is stick a pin in it at the moment. Hopefully we don't get a hybrid solution (less likely I think) of 5-6C and lots more clag.

The met update today totally wiped out cold and mild wet n windy by Saturday. 

They must be seeing something we're not.

The models have teased us but no true cold has really every arrived. What we have seen is a substantial amount of cold and grey days with cold rain or sleet yesterday there was sleet and wet snow over Moors and along A361 link road from Tiverton to Barnstaple and again today we saw drizzle at +4c in many places which could have been -2c with snow grains. Tonight we saw cold patchy rain at +3c and the same is forecast for tomorrow night - more cold rain and mist/fog at +4c, even worse it's patchy cold rain. YUCK

GFS fails to bring the cold this morning. Control goes very flat indeed. 

ECM might be a bit better but it’s looking like last chance saloon for anything decent.

And the GFS 0z has stuck the final nail in the model coffin - and demonstrated why the Meto might have had prior awareness of how the models would pan out. The cold air stays out East, and we get more meh!

Disappointing compared to yesterday for cold, high is a lot less dominant and the Atlantic a bit stronger. Certainly makes interesting model watching. No tears!

Just 5 GFS 0z pert’s retails a cold conclusion deep into FI. Other models may be better - awaiting ECM.  Is this a wobble or a new trend....?

Still time for change but it does look  (once again) like a close no cigar winter for the top escapologist UK.The only difference next two weeks is that there is some serious cold air out to the east which may fuel the driver but unfortunately the air from Africa is getting warmer too which cancels it out somewhat.

WX average temp & pptn charts not updated from yesterday.

GFS Op 00z:  Until about Thu 13th HP over Scandinavia brings in SE-lies with cold but not very cold air. The HP then divides, part going to Greenland and part forming a narrow ridge down the North Sea. This is enough to hold off any really cold air from the east and with a closer approach  of LP from the Atlantic milder S-lies develop, strong at times, until Fri 21st, when small troughs break off from the main LP and bring cooler unsettled weather from the NW. Even though the winds go back S-ly, it's still cool as Britain now has returning polar maritime.

ECM: differs from GFS after Sat 15th when the Atlantic LP moves steadily SE to Biscay 970mb Wed 19th, keeping the faux cold SE-lies going;  a lot of cold air both over Europe and the Atlantic but none very close to Britain.

GEM: more like GFS but showing signs of moving the LP to Biscay by Wed 19th.

GEFS: mean temp stays near norm but there's too much divergence between runs to deduce any trend. Yesterday' ultra-cold has gone. A little rain early and dry until Wed 19th for the south; shown in more runs in the N but no great amounts.

MetO forecasts for all but the far west show continuous cloud cover with occasional light rain here and there for the whole of next week

I wouldn’t make a forecast for the 6-10 day  period based on what we’ve seen over the last few days, and a return of significant cold clusters is as likely as a move away as signalled this morning.

Powder dry and keep riding.

As I mentioned the other day, I think the current situation is one of those like we have seen from time to time in past winters where the models are struggling to deal with a blocked set-up.

From what I can see, at the moment the models are still trying to work out what the LP in the atlantic will do a week or so from now and what path it will take as it attempts to move eastwards. A lot seems to be hinging on that right now and until this is settled one way or another, we can't be anywhere even approaching sure of what happens from mid-month onwards. There is next to no run-to-run consistency and cross-model support for any one outcome at the moment and I don't see how anyone can confidently call what will likely take place a week or more ahead until such times as we have both of those.

This run of groundhog day modelling..has to end soon.
