GFS Para is looking quite interesting in its latter stages as well.

A few more days/runs with changes and developments like this afternoon and things may look very different. Will this evening’s output be part of a transition or just a little blip?

No, there is no output that sends the High north, and there is no point in wasting time with a continuation of the High on top of us, we are going to see a well advertised zonal reset by day 9/10.

Apologies I thought from your comments thatt you meant they may change the current forecast not the one from days or weeks ago?

From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.

What is pretty clear now in my view is that ECM seems reluctant to follow GFS in bringing back the atlantic from late next week, although GFS is now indicating the HP to stick around for a little longer than it was a day or two ago. If anything, ECM now seems to be going for a reinforcement of the HP from a new cell from the mid-atlantic.

But yes before that quite a long coldish spell, although  the -10C isotherm (which I consider the benchmark for a proper cold spell) never quite arrives.

Also the ECM 12Z looks a little more encouraging with the high building northeastwards a tad.

The main positive thing is that the very wet runs seem to have diminished in the last day or so.

With the current set up the jet is being forced north; of course some energy in the southern arm would be good but it's fairly clear that we don't have a 'sinker' set-up however much Ian keeps repeating it.

I'm afraid that the fact is that his insistence on the Atlantic winning out has been quite consistently overplayed this winter so far and there's little in the current output to say that record will be changing anytime soon.

The output tonight has somewhat upset that scenario with mid latitude blocking on the menu.  Slow moving slow changing. There is still the outside chance that the block will gain traction slightly further NW too, giving a glancing NEly to the SE quadrant on 3/4th Jan.

What is going to happen to any surface high that runs up against the existing block?   It either bumps into the upper high and/or stalls (because the jet isn't pushing it eastwards).     

It could all get flattened out at Day 11 but the block may hold.

Of course it will. Limboesque conditions since the Autumn will continue without relent. And you are right, no real power in the jet stream to be had, which says a lot about the current state of the atmosphere. I've recorded higher windspeeds in June than this December, and this in itself is unnatural to the point of obscenity.

Lets see what the GFS does this evening but as someone said earlier ECM not without interest but still too far to bring any proper cold and snow to these waters.

Trends better on the runs tonight GFSP looks good, ECM high orientation building NE - detail not important and zonal not looking like steaming through as far as I can see so that cannot be favourite very much in the balance which gets the interest up going into the 2 coldest months. SSW could give cold the upper hand
