Merry Xmas campers!


Finally, there seem to be some more interesting model runs appearing now, after weeks of both tedious output and weather together. Whether or not the models are really onto a potential pattern change or they are leading us up the garden path remains to be seen for now, but interesting viewing all the same.

ECM still not interested in any Easterly as per ECM32 update yesterday, so until that smells the coffee I would take what the GFS shows with a huge pinch of salt as we've all been led up the garden path before with these set ups. Having said all that as long as the block remains in situ and WAA continues to be pumped Polewards from both sides the PV will come under attack in a pincer movement and thus be banished for eternity, well at least for a few weeks.😁


Merry Xmas to all and may you all have a prosperous but more importantly healthy New Year.

South-easterly wind? - Will this bring snow to it's northern edge?

Notice a slight change - it never really sweeps eastwards and get's stuck across the Irish sea and N. England- bugger for Cumbria!).

Also running the 12z chart notice the HP's building across Greenland and Russia and Scandi? - Is this a sign of a blocking pattern emerging or too early to tell?

Happy Christmas everybody. Looking forward to a New Year crippling easterly that will paralyse the country in time for the return to work in early January. Now for a beer.

It certainly looks like a pattern change. It will be interesting to see what the 200hr+ charts on the ECM op run look like in a day or two

I just think it will take a few bites of the cherry before we see the goods, but the most important aspect is the NH profile which still looks rather good.

Yes but doesn't the HP look a bit further east?

I hope again that this insanely warm December can sow the seeds of a cold spell in the New Year.  At least there is the prospect of some seasonal temperatures, which will be something of a novelty.

Met O has changed its tune somewhat and appears to be moving towards are more (edit 1) blocked  solution.  Certainly a robust block even if its not of great UK influence.  A step in the right direction. UKMO 144...could be good down the line... edit 2 .better then the 12z GFS anyhow....
