Ref Gooners last post...


This is not what we see on the Meto general forecast this morning:


'Dull and damp on Saturday, with heavy rain Sunday. Becoming mild but windy'.


The contradiction is also illustrated here:

The GFS more in line with the figures you have posted.  (As you are north of the M4)

ECM ens anomalies indicating a very wet pattern. Day 8:



NAEFS at day 12 shows the trough weakening and the Euro high re-establishing bringing a return of mild to Europe.




So my outlook: very wet and much cooler up to at least day 10 with snow possible on high ground in N, then probably becoming drier but milder.

The GEM chart posted above, and the GFS 06Z shows a much slacker look over the UK than recently. They look as though there could be some opportunities, but those anomaly charts posted by Fothergill above look pretty hopeless. 😞

The only thing we can be anything like sure about at this stage with the current model output is that the exceptional mildness of the past two months looks like coming to an end, for a while anyway. That might perhaps help to provide a bit of relief for flood-stricken northern areas from the heaviest rains such as those seen recently. The only thing is, even small amounts of rain in these areas could and likely will cause problems for a while at least, given the sodden state of the ground.

The thought of replacing mild zonality with cold or cooler zonality doesn't really fill me with much enthusiasm. Roll on Spring!

TBH this is all academic, I can just go back to commenting on how the polar vortex continues to weaken, even if we don't see a cold spell in the first week of January, the potential gets better and better as we go through the month. At 10hpa the polar vortex is nearly at risk of being split:



The tropospheric polar vortex is located in siberia, well to the south (and 180degrees out in terms of longitude) where it should be.



 


By 384 hours the polar vortex is virtually in china and there is debris everywhere in the rest of the NH



My prediction is the first colder than average January since 2012 at the very least with a good chance of actually beating 2012.

Any future easterly may have a bit of a bite now however unlikely it looks viewing today's output. We just have to wait and see now how that WAA affects the vortex later on in January - as per Quantam's post some interesting possibilities at least.

I must admit I hadn't realised that Jan 2012 was colder than average; I would be surprised if it was colder than Jan 2013 as that January did have a fairly persistent, although not severe, cold spell from the second week of the month until just before the end of it.

Without being able to check right now, Jan 2012 was around 5.5C ??


 


Colder than average Jan/Febs have only followed above 5C Decembers twice in the last 28 years.


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.
