Very different run-up compared to 2010. The MetO long-ranger at this point in November 2010 was already talking about well-below average temperatures at the end of November going into December, and that outlook was rock-solid for quite a while. Currently the signals for something remotely similar are weak at best.

What needs to be remembered IMO is that at this moment in time, we are still just under three weeks away from the start of the meteorogical winter. While the models may look predominantly mild/very mild at the moment until the later stages of GFS FI, a lot can and quite likely will change in the model output over the coming three weeks or so.


It's worth remembering that we haven't really had a notably cold opening to any winter since that great December of 2010. Although it was a little chilly up here at the beginning of last December, it wasn't anything particularly severe and we didn't get our first snow here until Xmas night IIRC.

From what I recall, the models that we can see didn't really suggest anything particularly cold during the first ten days or so of that month; it was only when we got to around mid-November 2010 that the models began to show heights over the Greenland/Iceland region rising noticeably, pretty much the same thing that happened the previous winter which led to the Dec 2009/Jan 2010 freeze I think.

6z GEFS mean at 240 hours. There are several members now showing wintry potential from the east.

Meanwhile, here's the ECM mean for 240. Cool and settled looks increasingly likely as we go into the latter third of the month, IMO.

I can finish renovating this pool, dry weather at last, perhaps beyond  http://www.meteociel.fr/modeles/gfse_cartes.php?mode=0&ech=204 As long as it not too low temps in the day for cementing, and there is no model change

Not sure what to make of the models atm, other than it looks settled for a fair while. Whether the HP is static enough to allow some low level cold to form or indeed clear enough for some sun and frost is a bit of an imponderable.


GFS seems keen to reload the HP to a more favourable position, with the 12z OP in deep la la land showing how to get a decent early winter cold spell courtesy of it dropping a big chunk of the PV in to Scandi, with HP over Iceland nicely positioned to help the cold flood over most of Scotland and England I'd have thought.


The initial mild/warm HP phase seems pretty nailed on now, just have to wait and see how long it hangs around and whether it ends up somewhere that's conducive to getting some properly cold air over us.


It'll be interesting to see the Ens later - the 6z set had a split developing with a clear cold and milder cluster, suggesting continued HP dominance looks favoured but positioning as you'd expect far from certain.


All in all not a bad place to be in as we head towards the start of the silly season and the imminent dry mild stuff should be fairly pleasant to cycle in, which is a massive bonus for November

Well, looks like a Scandi HP is on the cards from every major model, starting next weekend.


Will it then retrogress towards Greenland?


Northern blocking is the form horse for the early winter in any case - looking good for some enduring frosts at least.


New world order coming.

GloSea update has just been issued. The mild signal has now gone completely and it favours below average 850s in the south with a positive pressure anomaly to the north of the UK. Other seasonal models from national forecasting centres offer support so perhaps the Met Office will start talking up the prospects of a cold winter.
