If/when we do get an easterly it’s going to be painful to get there!

(I might start copy and pasting, only so many different ways I can find to say the same thing!). 

Depending on whether you want cold or mild, it's a pattern that's very close to your desired outcome, albeit may not get there. I'd guess we should start to get a bit more certainty over things over the next 2-3 days although if the HP remains to the east longer term then I imagine the cold tease could carry on for a fair while yet.

It's only the brisk wind that is making the current 5 C & 2 DP feel quite raw. I expected all that and yet still cannot help feel disappointed. 🤣

The lack of deep cold to tap into and the higher than average SSTs are telling. Today's winters certainly are pale shadows of their former selves, it's one of the very few reasons why I'm glad to have been a 1980s teenager where I got to experience drifts taller than me here at my coastal location. Still, a skeg into the models are showing not that much in the way of stormy conditions for a while. Roll on for the first bit of actual Spring-like warmth, but even there's little of that on offer in the medium range outputs.

The op was mostly at the top end of the ensemble set for 2m and 850hPa values and again the median was below the mean.

What there's no support for in the MO at present, is the block and the cold to our East being completely blasted away by the Atlantic. As long as it stays close, there's a reasonable chance of it advecting Westwards through time.

The vast majority of “proper” cold spells at range never materialise. Every winter scenarios are ten days out and never come to fruition. As someone pointed out yesterday, if the charts of ten days ago were here now it would look very different to what we currently have

The latter half of the 06z GFS OP run gives me that bit of hope.

True. Sun on the skin can make you feel warmer than the air temp would suggest, given that the sun only really heats up surfaces anyway and not the air itself.

Looking back at the early pages of this thread I don't think I commented about the ens showing a proper cold easterly once, it was mostly that some of the ops were showing decent cold but the ens were never strongly on board.  There were a few comments re the current easterly being modelled and showing a mean of -8c, which is pretty good going as that's what we currently have. 

I'll happily link various posts etc. and appreciating people always view the charts slightly differently to others but my read then was an easterly was likely, after I'd had a few days of thinking it wouldn't get this far west, but that depth of cold was very uncertain although a couple of days of -7 to -10 air looked likely. There certainly was a signal in some of the ops etc. for a second more potent easterly but never one with strong support (much like we still have that signal but never one where all the ens suites have suggested it's the more likely outcome).

On the basis of what I was writing at the time I'd tend to disagree with your comment. It's all academic of course, we've got an easterly, the uppers are circa -8c and it's currently 2.1c and raining, with DPs stubbornly in the 1.3-1.6 range 😂

 

Eyes down for the incoming 12zs. If I was a betting man I'd put money on us still being none the wiser for the medium to long term, albeit I would have a bet that the majority option won't be to bring decently cold uppers in.

With sub zero 2m temps and -10 uppers the warmish N Sea would actually benefit us in terms of convection. Now it’s a curse as it’s mixing out the already very marginal airstream and we’re left with graupal and sizzle and general misery.

Faux cold is pretty common, but I'd say at least 1/2 faux cold easterlies transition into something real. And faux cold has imo always been a thing, but you so often need that initial 'poor man's' easterly to tame the atlantic before you get the true event a few days or a week later.
