After a brisk three or four days of northerlies and the associated snow showers the 00z GFS provides a more settled theme as we head through the weekend and into a new week as high pressure drifts eastwards over the UK and towards Europe blocking a return to the colder northerlies predicted in previous days. Its a similar theme on the GEM and UKMO with doubtless some cold daytime and night time temperatures to come.

Northerly or UK high, the only difference down south is the wind speed between those 2 scenarios. 


Time to wait and see what the next cold evolution might look like, in accordance with the met Office predicted cold first half of December.

A much milder outlook in the London Ensembles too, albeit 2m temperatures will no doubt remain subdued under the High pressure!

Funny how this still happens. The models lead us up the garden path, show us a delicious Greenie HP and then one backtracks, followed by the others.
This despite billions spent on computers, software, sensors and satellites - they are still clueless after a week at the most.
New world order coming.

I think the Beeb might change their thoughts slightly in the 21:55 forecast .....not much offering for a straight Northerly early next week, looks like HP sitting over us.....of course much can change.


 


In saying that the UKMO doesn’t look that bad at 144

The last time that the models correctly picked up on a series of northerly blasts seems to have been the November 2010 one, as that was modelled well from 14 or so days away. Why that one was picked up on so well, whereas successive ones haven't is open for discussion.

Of course the GFS still sets up a big northerly plunge in the latter stages - it still seems to be keen on that pattern, it just always fizzles out once it gets to the reliable time frame!

A note to casual readers, and it may come as a surprise, the 00z runs might have or it might not have, nailed next week’s weather.


Before then increasingly cold for the next three days.


 Even the milder GFS op run shows the following temperature anomaly http://wxmaps.org/pix/temp4.html 


(And for what it’s worth the GFS ensemble data have more runs, eight, breaching the -10°C t850 mark than any time this reason.

As Michael says, it could change - and undoubtedly will - but as it stands it’s looking less likely that we’ll see sustained cold.


The nirvana of cross-model and ensemble support is still not a guarantee.  Particularly for when the evolution relies heavily on a particular set of events falling just right.  In this case we were relying on energy slipping east from Greenland and diving SE and the high retrogressing to form the block. The high is now expected to stay too close and the upper heights near Greenland haven’t rebuilt and that changes everything.

Don’t worry about them they get paid plenty of money to do it most of them are not bothered either if it’s cold or mild it’s a job.
