Can't tell if thats serious or not? Haha. Also seems like as hoped, the warming is moving foreward in timeframes rather than staying stagnant in FI and its nice to see such a strength of warming still predicted not becoming watered down.

In fairness to the GFS, its 12z looks very similar to the 18z Same timeframe..

Could someone do me the honour of explaing 500hpa charts? Are they linked to inversions? For example i know this will unlikely come off, but what do they mean?

We really do need to see that Russian high just bugger off to see anything remotly sustained of cold weather post christmas and new year, it only seems to build stronger again on the 06z, however although FI now is leading to a potential split vortrex at T288

-5's are just scraping the southern cornwall coast actually...

A definite shift eastwards on the 18z, looks better already... and whats this?!!?!?

Certainly what GP has alleuded too... Realised its quite off topic. Sorry.

Someones got sunglasses on in the Arctic...

GFS wants a nice little white christmas for the south...

Why say that, with no evidance to back it up just a completely ridiculous post? Dont post unless there is substance or reasoning to your beleif.

Is it feasable for a low to zip across the atlantic like that in 24hours though?

The differences between the 06 and 12z at just 114 are stark 12z... 06z Much better 12z imo.

Thats this mornings 6z for the 23rd, not T96...

06z seems to bring us a nice burst of warmth Followed by Nice integration into the vortex at 384? Novice speaking here, but willing to learn.

who wants to start the next chase?

Complete novice here, but seeing as there are no other posts for me to drool over, is the warming becoming slightly more watered down? and not as well integrated?

The differences between the 06z and the 12z are laughable 06 12z

Could you post a link please?

GEM still producing the goods at 144 http://www.meteociel.fr/modeles/geme_cartes.php?&ech=144&mode=0&carte=0

I may be wrong here, but i was fairly sure the effects of the strat changes or an SSW would only take 20-25 days to reach us, which is more 3-4 weeks?

So maybe after all the GFS was onto something a few days ago as i said earlier, before dropping it and re-developing it? Lets not get ahead of ourselves Also, can i ask you all something? Not that im superstitious.....but dont tell ANY family memebers or friends of the potential cold, as when i do this it always seems to be the next set of models that destroy all hope.

Notice at T120 core of the low moves slightly south aswell

Thanks @SK and @Panayiotis But even earlier than that, at 288 (19th december) on the 7th (12z) http://www.meteociel.fr/modeles/gfse_cartes.php?&ech=288&mode=0&heure=12&jour=7&mois=12&annee=2012&archive=1 then 18z at 336 (21st december) same thing... http://www.meteociel.fr/modeles/gfse_cartes.php?&ech=336&mode=0&heure=18&jour=7&mois=12&annee=2012&archive=1

One thing i think of in regards to the breif easterly shown around the 22nd tonight, is that 3 or 4 days ago there were a succession (4-5+) runs showing a N'easterly or Easterly at the same period. GFS has been known to pick up a trend, drop it, then reel it in again, im clearly not getting my hopes up but it is a glimmer of hope for anyone is search of cold and i do hope the trend begins and continues. If anyone could post a link to accessing previous charts i would be happy to (try and) back it up with these, or suddenly realise i was talking a load of tosh
