It does feel like the rest of the world hates the UK when we are surrounded by wind and rain and yet it looks all calm and peaceful everywhere else. There is a certain element of "what have we done to deserve this?".

This Saturday's output should show what I mean: http://www.weatheronline.co.uk/cgi-bin/expertcharts?LANG=en&MENU=0000000000&CONT=euro&MODELL=gfs&MODELLTYP=1&BASE=201401270600&VAR=uv10&HH=120&ZOOM=1&ARCHIV=0&RES=0&WMO=&PERIOD=

I've long since thrown in the towel regarding looking for any proper wintry weather but I'm now yearning for that first bit of proper spring-like warmth as the sun creeps that littlle bit higher above the horizon with each passing day. Yes, I know, it's still only coming up to February but I remember how the sun used to be very effective while in a greenhouse at around St Valentine's day onwards.

It's been record breakingly cold over the USA so maybe that has been driving an active Atlantic, along with a misplaced Jetstream. However I do share your feelings. I often think the UK would be better if we had an enormous polytunnel covering these rain lashed islands!!

If this mid range modelling is in any way accurate, the situation is going to worsen in both locations.

Before viewing the model runs these days, I have the following question in my mind...


"So... how fridged are we?"


 


I swear, that's the choice of words I use 


 


Anyway, GFS serves up yet another super-soaker FI, and it's not hard to see how we are likely to get there, as the weekend trough acts to send warm air advection up the coast of Scandinavia and promotes a build of heights there, but in doing so it ends up situated above the 'end' of the strong Atlantic jet, which means that upstream disturbances rocket across the UK and develop rapidly, only to grind to a halt upon drawing near, resulting in stalled or slow moving frontal systems across our sodden land.


Now here's the major problem we have; if that weekend trough was to disrupt more and end up further SW, we'd need that adjustment to be very large in order to avoid ending up taking a different route to the same longer term result. So large, in fact, that you really wouldn't count on it.


...so we're looking for the trough to make less progress east by Friday (+96h), in which case a ridge from the SW could entice the Scandi Block close enough to keep us clear of the fronts and perhaps under a somewhat chilly regime if continental air gets into the mix.


The 00z ECM op run actually managed this briefly for day 7, before the invasion of the tail end of a trailing front on day 8 followed by the westerlies returning... day 10 gave uncertain prospects, however, as energy dug south in the Atlantic and allowed a ridge to build up toward the UK from the south. With the trough to the west of Iceland decaying and about to be met by an amplified upstream trough, shifting the mean trough position west a bit, the day 11-12 evolution from there could be a ridge buffing up the Scandi Block such that it extends across the North Sea and influnces the UK more convincingly.


 


So yeah, there's that last glimmer of hope left for the next fortnight, and within the hour we'll know if it remains or not...

Tonight's 12z ECMWF and UKMO and GFS 12z runs, have Generally average Minimum and Maximum Temperatures, and some spells and areas of West and North UK at times get slightly or a bit more below average both night and daytime, in Active low pressure as it sends Colder Westerly and NW Flows, this spreads East and South but is less cold as it does spread in with west and NW winds.

There looks like a drier spell following Friday and Saturday's Stormy and Wet weather for the UK, for Sunday and first part of Monday, it gets less cold by Tuesday as less cold SW flow associated with North Atlantic Low pressure domination to spread in UK, through Wednesday and Thursday 6th and 7th Feb. 2014, plenty more Wet rainy and Milder weather is set in forecast from NW and N Atlantic spreading Windy and both mild but later the Colder West flow after mild SW flow, looks like heavy rain and blustery showers are not going to bring any respite to our Flooding rains and rives 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.

Now that February is in the reliable time frame and the models are getting worse instead of better there can be few members on hear who are not desperate for spring.

The winters of the 00s were poor but this is desperate and I will just be glad when this excuse for a winter is over.

My God even in the winter of 1974/75 Birmingham had had 3 days with lying snow by now but this year the city hasn't had 3 days with a blob of sleet!.

Truly, truly awful.

Andy

PS In winter 1988/89 Birmingham had also had 3 mornings of lying snow due to an excellent snowfall in late November and the dry, bright mildness of January was far better than the grim rain of this year.

If anyone can find a worse December/January in the West Midlands than 2013/14 I would love to see it

Even the 'easterly' has been downgraded now to two days of virtually average temperatures - as a curiosity in future years Winter 2013/2014 will be one to review to see how mild and wet a winter can be. Still a few weeks left but indications are nothing is going to change anytime soon.


I do wonder if the persistent warm anaomly off the coast of Alsaka has something to do with it- it appeared in the Summer and is still there:


http://www.ospo.noaa.gov/data/sst/anomaly/2014/anomnight.1.27.2014.gif


We were all wondering what effect that might have and now we know - of course not that simple and could be something else for the cause of this, just seems odd that such an unusual anomaly coincides with what we have had.

Yes and it's a nap now I feel that we'll get a cold, miserable Spring as the first half of February looks a write off judging by tonight's charts.

Hi everyone. Here is the evening report on the latest 12 noon outputs from the NWP for today Monday January 27th 2014.


All models show a slowly filling depression slipping slowly SSE over the UK and down over France by Thursday having largely filled up by then. Over the next 48 hours further very showery weather persists over the UK with showers or longer spells of rain with hail at times and sleet and snow over the high hills of the North. Winds will be brisk from a West or SW point in the South then an easterly point in the North by Wednesday. Thursday then sees a spell of rain and hills now move SW on an occluded front dying out over the SW later in the day. Eastern and Central Britain may see the isolated wintry shower or two briefly before a deepening depression to the NW of Britain sweeeps any cold weather away with freshening Southerly winds carrying rain East across the UK on Friday with some snow over the hills for a time.


GFS then shows a very unsettled and windy spell with winds between South and West throughout with showers and longer spells of rain occurring with all too much frequency as deep Low pressure areas successively sweep NE over the UK with temperatures very close to average for early February.


The GFS Ensembles show a wet and windy two weeks with the Atlantic in total control of the UK weather with Low pressure after Low pressure ensuring that the weather doesn't allow any  recovery in conditions affecting the flooded areas of the SW. Temperatures will remain close to average and after a short chillier than average spell for a time this week we become rather milder than average in places later.


UKMO tonight has conditions on Sunday governed by a Low pressure area moving away to the North taking it's showers with it and allowing a weak ridge of High pressure to cross East and bring a drier spell of weather for many ahead of a new Low pressure area approaching from the SW to start next week.


GEM is also painting a very unsettled picture with showers or longer spells of rain in strong SW winds in association with Low pressure encircling over and to the NW of Britain.


NAVGEM is very similar with Low pressure well established to the NW of Britain with strong winds and spells of rain and showers sweeping NE on regular occasions from this coming weekend.


ECM too is very changeable but perhaps a little less deeply unsettled over the South for a time with average temperatures and winds from the South or SW for most of the time.


The ECM 9 and 10 Day Mean Charts show the likelihood of Low pressure being positioned just to the NW of the UK with a cyclonic South or SW flow across the UK in pressure levels at sub 1000mbs over the majority of the UK. With relatively mild winds from the SW and such low pressure we can only expect the prospect of plenty more rain and showers, probably heaviest in the areas that least need it, being the West and South.


http://www.wetterzentrale.de/pics/Reem2161.gif


http://www.wetterzentrale.de/pics/Reem2401.gif


The GFS Jet Stream Forecast maintains the flow close to or over Southern Britain over the coming few weeks. The flow will be just to the South through the firsts week before it shows signs of strengthening strongly again later in the low resolution part of the run.


In Summary the Atlantic is gaining supremacy more and more with each run as the embers of the cold spell become reduced to one day on Thursday. With successive deep Low pressure areas spiralling around to the NW of Britain from all output to a greater or lesser degree the weather will remain very unsettled and often wet with showers or longer spells of rain in brisk, sometimes strong SW winds and temperatures recovering back to near or even a little above the seasonal average in the South at times.

I don't think it would be possible for the same sort of westerly to continue into the summer. If you want a warm dry summer, though you would still be wanting blocking of some description.

Summer could go either way - anyone's guess really

Evening all.

Stratopheric warming has been chipping away at the vortex for some time and a possible early final warming has been making an appearance on GFS operational.

The below looks like a splitting stratospheric vortex at the 30hPa level 204h out which is on the edge of the reliable at that level.

Even if all the controls and ensemble members show the atlantic roaring in, they'll change.

A week from now we'll be looking at some possible solutions that will reinvigorate the roller coaster for a final winter surge of enthusiasm.

I'm personally not sure if we'll get anything spectacular but following a steady (if unspctacular) strat warming I would not bet against something cooler, if not cold, for the remainder of winter. And probably into Spring.

tbf though strat warming is coming into the reliable timeframe now. Last half of february still has the potential for a wintry sting. 


NAVGEM is pretty intense

onto the real modelling and the extended ens say forget the first half of feb - but you already knew that !


the other thing i dont understand is the comments that events in the strat will change the model output when the models realise whats happening in the strat.  its the same bloody model. it goes from the ground to the top of the strat. so if its modelling changes in the strat, it will also model their subsequent influence on the trop.  if you are saying that there could be improved model runs in two weeks time when any downwelling has come from a warming then thats fine.  (fwiw, exeter dont think there will be anything notable occuring in the strat which will significantly affect the trop).

What I find amusing is talk of SSW effecting our weather come mid February, correct me if I'm wrong but doesn't the PV start to wane anyway at this time of year, so surely it will be down to the natural demise of the the Stratospehre.
