A jug and then a Kettle then Jarred GFS.
OMG, 12z GFS, It does Retrogress next Week on Wednesday 4th, and through Thursday 5th December, the Large Polar Vortex locates in NE Atlantic North and znE of UK, and we get to trap the short Wave Low on Thursday, that then brings us A Very Cold NW and North flow from Thursday's Deep LP and Very Strong Severe Gale West winds with Squally showers and a large batch of heavy rain- merging into more prolonged Showers, a chance of Sleet and HEAVY SNOW Showers for Friday 6th December 2013- which the GFS 12z run persists over UK even on Saturday 7th December.
We see A large Anticyclone High this Weekend which moves East then West, with Greenland To NE N Europe SE Arctic and Svalbard get more Cold Weather and West to East Tracking Low Pressures.
On Monday plus Tuesday we see more High Pressure, and by Wednesday and Thursday the Lower Heights Over Greenland be replaced by large growing High, and A zipped away Low from NE USA NF and NW Atlantic, is expected to remove the UK High, by Thursday.
A Deep And Separated Deep Low in NE USA and Newfoundland and Another Deep Low in NE Canada Arctic link together- and Greenland High as well as the New Retrogress Block High establishes in North Central Atlantic, well out West away from us.
I am very interested in the next 6 days- GFS and UKMO plus ECMWF need a lot of careful Watching.
We could turn very wintry in som parts of favoured Britain.
And seeing the PFJ Low transported SE to the Meditteranean this Weekend and then watching a slip off to a PV Low set over UK on Thursday next week and beyond- looks very interesting.
We then Could re Double the opportunity for Cold NW flow- even a full blow Arctic plunge- twice, as looking to w of Greenland and the Newfoundland Low link up to Arctic area Low NE of Canada- if they shift SE and help Re develop again the a High over Greenland, plus send those merged Polar Vortex Trough Lows to cross SW then move out from E Greenland to Iceland and we get more High riding in West N Mid Atlantic for the 2nd Week December round two NW flow it may turn out as a very prolonged Spell of Arctic Weather over N and West a Central Europe and the UK- right through to Mid December.
We have to be very careful each day's Models Outputs could still change this forecast, so it is not really highly possible.
My experience says that the weather may well be kind in December 2013, I say to the GFS, UKMO and EMWF, just treat each day with faith, thanks for trying to bring a change if you are able to put in your thoughts and pay attention and be sensible with us at The Weatheroutlook then you will be treated fair.
Do not throw us down very easily- it waste a lot of our time as we try to be nice members on here.
Chill Out Central and Much of USA inc. the West East and North we know you like your prolonged arctic Snow and long cold winter's and the Same goes for North and NE and a Central Europe.
Enjoy your snow, but try to get some over to the UK, A Cold Winter Spell is quite a picturesque and Tranquil Site and you can share some with us at a Model Output- we get very upset if we get spoilers.
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.
