Tiny short wave being picked up on 6zgfs to our n/e does make quite a bit off difference tempting also udercut from the s/w

I think it's a case of enjoying, or rather, making the most of the high-pressure theme as shown in nearly the entire length of the hi-res time frame (for the next 7 to 10 days - a shame it isn't July!) and let the low res end of the model outputs worry about what it's going to do next, even though they are showing the Atlantic-based stuff trying to charge back in (a long way off in forecasting terms and probably the models going into default mode).

There is significant variance in the GEFS relatively early on but none of the solutions look particularly cold.

And if I were to reference members who have experience enough to interpret the output in a way 'unbiased' to any particular weather type and using the data freely available, Martin's analysis, along with Gavin P, would be high on the list.

Ian Fergusson over on the other "channel" says things are "finely balanced"


I think that's the right way to sum up things.

GFS 06h ENS reflect that fine balance.144h and 240 h Atlantic :Anticyclonic is 50:50 .As Brian says none of the options looks particularly cold.

GFS12z out to 180 hours is looking pretty mild.


The GFSP is running 2 hours late today and probably won't appear on TWO.

I would add James (Stormchaser) to the list as well. Three knowledgable and unbiased providers, and we are lucky to have them

Slight majority in 12h ensembles for anticyclonic -but few as cold as this little beauty!

Just flicking through the latest runs and the pendulum swings again in FI towards a less cold solution, even quite mild for some. Quite a strange jet profile these next few days don't you think?

GEFS12z are milder than the 6z suite but with a couple of colder options tucked in. As a punt I'd not be surprised if we end up with some notably mild weather in the next couple of weeks. Sahara vortex?

IMHO the first cold wave (assuming we get one this winter) will effectively be used just getting the atmosphere in our neck of the woods back to normal.

Well, the Met Office seems to be revising its short/medium term forecast constantly - the BBC site is showing maximum of 8C and min of 5C for end of next week, and it was only 8C outside my office this afternoon!! That's about 4 degrees cooler than the outlook just 2 days ago!

That is exceptionally warm for November Polar Low but it looks as though the air is sourced from the S Atlantic on that chart with a SW wind as opposed to a S wind.  I agree with Gandalf on this one - I believe you can only get exceptional warmth at this time of year from a SW'ly steering up warmth from the S Atlantic.


Anyway, back on topic - models looking interesting in terms of future cold prospects, and it could not be any more different than this time last year.


Hopefully we'll get some winter cold this year.

GFS18z 10C colder on Sunday in the south than GFS12z. Can't remember seeing such a huge change from run to run at this range.

I agree Brian.  Looking at the ensembles, theres a massive range of scenarios on the table at the moment


 


Theres good agreement for the next 3 days - after that it goes Pete Tong.

I think the overall trend will be for higher pressure, and cooler temperatures - with lighter winds leading to frost in places.  Funny really, when you consider the detour the models have taken to arrive at what is fairly typical weather for this time f year.  


 


Personally i wouldnt mind a bit of fog at the moment for some seasonal photography.

Wrong thread but kinda ties in with the model output - the metoffice have now mentioned the possibility of a pertiod of below average temperature. Also a mention of snow for higher grounds in north.


UK Outlook for Saturday 22 Nov 2014 to Monday 1 Dec 2014:
Western parts of the UK should see some spells of heavy rain and strong winds through the weekend, with the east generally staying drier, although a little rain is likely to spread eastwards at times. The unsettled weather is most likely to continue into next week over western parts with spells of rain spreading in from the Atlantic. Eastern parts will continue to see the best of any drier and brighter weather, however rain is still likely here at times. Temperatures will mostly be around average for the time of year, although they may be a little below average in the east during the start of next week with an increased chance of frost and fog overnight.


UK Outlook for Tuesday 2 Dec 2014 to Tuesday 16 Dec 2014:
The most likely scenario is for a continuation of unsettled and windy weather to affect western parts of the UK. Spells of rain are likely further east too but the best of the dry weather is expected here. Temperatures are generally expected to be around or a little above average for the time of year, although this does not preclude the possibility of a few colder spells which are likely during any quieter periods of weather. There is a chance of some overnight and morning mist or fog in places, and some patchy frost too - this may be more likely across northern areas where there is also a chance of some snow on higher ground.
