At the moment anyway. I'm not saying this will happen for certain, but things could change and change quite quickly if the right synoptic set-up for cold comes along. A large continental land mass like mainland Europe can cool down pretty quickly under the right circumstances, just like it can heat up quickly in the approach to summer.

indeed,,,you don’t need massive negative 850 as proven by some parts in the s/e to day

Sub-zero 850 hPA on a SE or E wind flow would be decidedly chilly in these parts!!

The 2009-2013 period measures up to any period in my lifetime for this region. And I'm nearly 49.

Having 20 years on you and 30 if you forget your early years the massive difference is the lack of blizzards and deep drifts, especially in the south and the total vanishing of the East Anglian heavy snow showers which were a part of normal life and rarely counted in our mind as anything special due to them occurring most winters.

You must have been lucky in getting snow every November. I have lived in the same location for all of my 41 years thus far, and even back in the 80s snow falling here in November was a pretty rare occurence according to my recollection. Only time I can recall it happening during that decade here was 1988.

Sorry David , just seen your reply , I agree . I have lived in N Oxfordshire all my life and November snowfalls are very infrequent

I remember in the 80's when my children were young freezing in sub-zero temperatures early evening one Bonfire Night and my car freezing up early one October evening. I'm not quite sure why people want to challenge the fact when us old fogies tell our tales of frequent and heavy snow falls. You'd think they would enjoy it and keep hoping for the same as i do - I'm running out of bloody time!

Yes, the outlook is still a generally cool one on this and other output. Not especially “wintry” and a bit messy.

Pretty much yes, but remember, I live on Dartmoor.


The problem is the Continental block is to our east, it's pumping relatively warm air across eastern Europe right into Scandinavia. In the past the continental block would be over Scandinavia but, well, this isn't the past. Continental blocks these days move relatively warm air about, in the past they moved cold air about. European blocks mean S or S wind not East winds (yes, I know we have Nlies but look to your east for what i mean, a fetch of isobars from N Africa to Scandinavia)

I think the biggest change probably has been to East Anglia. I remember my school geography book saying Norwich was the snowiest town in lowland England.

Take on the MO.


4 days into winter and we have already had a snow event. That's a once in a decade type event. We shouldn't forget that.

Certainly a move away from the barreling through of the Atlantic by the UKMO and ECM, but it remains a very wet picture with temps around average.

Latest GEFS. Snow row and downward dip in temperatures at the end may just be noise but worth watching.

Yes ECM not without intrigue still this morning.
More notably met office are now going for a milder blip next week followed by a cold spell into week 3 with severe frosts and below average by day possible over Christmas, drier in the west & north indicating a slack easterly of sorts.

I’m never a big fan of a reset. But the period between 11-15 December might be enough movement for things to shift in our favour. I love a blocked pattern, but it can either fall for you or against you.

it remains blocked on this mornings GFS, but need some of the pieces to move around a little bit.

FWIW snow cover still very patchy in W Europe and not much sea ice to the north so serious cold air may be a while arriving - which doesn't exclude local surface cooling Yesterday's snowfall in UK visible a a couple of tiny blobs  https://www.natice.noaa.gov/pub/ims/ims_gif/DATA/cursnow_asiaeurope.gif 


http://www.wxmaps.org/pix/temp4 backs this up though week 2 has some very cold air appearing - still a long way to the NE of us, but it's there. From the same site, pptn over W European coastal countries (notably week 2) and the Med (notably week 1)


GFS -A bit messy, but in summary, slack LPs for a week or so before the Atlantic wakes up again. Current LP filling and out of the way to SE by Wed 9th, Ural block still present. Atlantic trough from Rockall to Channel 985 mb Sat 12th but no real oomph in it;  a couple more LPs thrown our way by the Atlantic Wed 16th 985 mb Scotland and Thu 17th 965 mb NI both filling as they cross the UK. Something much deeper Sun 20th 950mb Faeroes coming up against the block which has by then moved N to Spitzbergen. Yesterday's SW-lies still there but being fed by north not south Atlantic so much cooler. 


GEFS - cool with good agreement to Fri 11th, then anything could happen with mean close to norm, perhaps a mild blip at first but you can find runs 7 or 8 C either above or below norm after that. Plenty of rain esp in S week beginning Wed 9th ( a minor but direct contradiction for this Sunday with rain shown on GEFS but dry in Meto). Snow row figures negligible 


ECM - much the same as GFS with minor differences in timing to end of run Tue 15th

I know November 1985 was cold and there were quite probably some snowfalls in some areas that month. I can remember the Novembers of from 1986 to 1989 quite well though (was aged 6-9 during that time), and of those, the only one which saw any snow in my locality was November '88, on the night of Saturday 19th as far as I recall.


As far as I have read, many Decembers in the 80s weren't especially great for cold and snow either apart from the famous exception of 1981.

We're going to have to be patient for significant cold to arrive to the UK.  But if the blocking continues and the PV fails to organise itself properly cold will arrive eventually.  I think Christmas week is probably the earliest we can hope for.

From what I can see of the model output, while are not looking at any likelihood of a repeat of December 2010 or the second half of December 2009 at the moment, we are not looking either at a repeat of December 2019 either. Still very much all to play for, IMHO.

I have sometimes wondered whether it would be better if there were only two GFS op runs per day instead of four, say at 00z and 12z as happens with ECM and UKMO.
