A hint of interest in the ECM Op tonight I see - not impossible of course but a quick look at the 240 position on the GFS ens shows essentially no similar options, although there's HP not too far away so it could happen. (Not to mention GFS placed the current block too far South as well).


UKMO (must admit I rarely look at that even though it regularly verifies second) seems to keep the HP cell marginally more south than the ECM at T120 albeit the pattern is broadly the same.


GFS ens are, as they have been for a little while now, showing a warm up around the 24/26th Jan, albeit average to a little above seems more likely than unusually mild. The unsettled signal is still there during the warm up although down here at least the rain spikes are reducing and the pressure ens show a fair bit of scatter. There does seem to be an increase in blocked members (sounds painful) right at the end of FI suggesting on this run at least GFS isn't going for a prolonged zonal spell.


Given the pattern of the winter so far a 3-4 day unsettled blip (down here anyway) doesn't seem like a bad punt.


Nothing particularly exciting on show at present but I don't think we're a million miles away from seeing some decent charts again soon. Whether any of them will verify if they do appear is of course rather debateable.


Before we do get to an unsettled spell (assuming it doesn't disappear from the ens) there's still the chilly weather to come for my neck of the woods. Today certainly felt nippy, compensated for by some lovely crisp sunshine. Not a bad day for mid January

Holy beheezers, been away for a few days...
Ensembles paint a mild picture later on.
Not sure what ECM is up to but there's no westward ridging evident as mentioned by some.
Lack of snow has turned some to hit the poppers!

It looks like something is brewing. As I said this morning my money would be on high pressure continuing to influence the weather in the southern half of the UK with the north under a weak to moderate Atlantic flow.

No backup from the UKMO for WAA to Scandi at T120, given how it correctly called the last retrogression that never was, no eyebrows raised from me yet.

Not a great deal between GFS and ECM st 168 if you ask me!

Quite how ECM got pressure to rise northwards so quickly by 192 is hard to tell with a 24hr view but let's see what the GFS does with it.

EC15 this evening still paints a more unsettled picture post day 10 but HP never seems that far away from the south or east. One positive, as tenuous as it may be at this stage, is that there is a very narrow window for some storminess to develop around the 30th, but no doubt this will be scarpered in the next run as overall, the NA jet still looks very weak right out to day 15.

At first glance there's not that much change in the last 4 days: GEFS still shows milder conditions from the 24th, albeit drier than before, whereas EPS continues to signal a warmup from the 24th as well.

However, that ECM op is intriguing, not least because the control run does a similar thing - and it leads to cold (but not deep cold) easterlies across the UK by 264. Easterlies persist for a few days before a low finally makes it across the UK with WSW'lies for all.

So the Euro op doesn't do it's Scandinavian HP this time and by Saturday week has us all in very mild south westerlies. Wonder where it sits in the group.

GEFS00z continues to reduce the Atlantic punch next week. The question for the south is how long a chilly continental influence is maintained. Personally I'm finding this winter pretty tedious but it's clear the dominant forcing mechanisms don't favour an active Atlantic. Feb / first half of March may throw up a few wildcards in the UK as the sun and spring begin returning to the NH.

Looking at the big three this morning I can see that High Pressure remains over or to the SE of England for another week. For Edinburgh we have already had 4 bright and mild days another 7 coming up. Edinburgh well placed for sunny spells and dry weather at least.

The Scandi HP get crushed and the cold air goes down the usual route towards Greece.


GEFS generally supports milder flow but signs Of HP development to the SE of the UK in a handful of ENS.The remarkable persistence of near continent HP could still continue.

Such a shame this HP domination didn't come in the summer, what a glorious spell we would have had. You can just feel it hanging on, influencing our weather until April and then sodding off come May and the warmer months, not to be seen again until winter 2017. What a wretched climate we have.

Back to the here and now and it's deja vu time again with benign quiet cool weather in the reliable timeframe proceeding something more zonal thereafter, still no signs whatsoever of anything remotely resembling a cold spell in any output though.

The certainty displayed here about what happens in the future is admirable. First we have nailed on exceptionally mild temperatures next week and now we have a washout spring!
