Not strictly relevant to MO I know, but my daughter has just emailed me to say they are having the blizzard of the century in Berlin at the moment.


They are so lucky with their weather in Germany.

On the face of it the models would certainly appear to be showing a “locked in” pattern for some time to come. There are also plenty of members on here who have far more experience and knowledge than I do when it comes to interpreting the medium to long range forecasts. However, I just can’t help feeling that by the middle of next week we’ll be looking at something completely different. There’s just something about the “certainty” of it all this morning that makes me feel mother nature is going to stick two fingers up to all the super-computers and their respective outputs. I have no idea whether it’ll be a cold easterly or a mild and stormy attack from the Atlantic but this scenario just looks ripe for something to pop up out of nowhere and surprise us all.


Sorry, I know this is the model output thread and not the “I have a hunch” thread but with the output looking so dull I hope the mods don’t mind. It could actually be another one of those occasions that remind us not to be too confident, no matter what the models are showing. I may be eating my words come Wed but I’ll be watching with interest.


Purely from an IMBY perspective I’d be happy to take another week or two of high pressure influenced weather, as I look out on another beautiful clear and dry winters day.

For the next two weeks 90% of the ensemble members have less than 10mm of rain. The Op offers all of 2mm in the next 10 days.


The ensemble shows two main groups of members by Day 10.  One group gives highs of around 8C, the other (including the Op) gives highs of around 3-4C.  I am assuming this is a matter of the alignment of the high, i.e. a continental drift of colder air or a SW drift of rather milder air.


With most of the models putting a stubborn high pressure cell somewhere to our SE we're going to have a flow from the continent across much of England and as the continent gets steadily cooler/colder next week under the high pressure the flow will get cooler.  That's what the ensemble says and it's what ECM, UKMO and GEM indicate.  Only GFS has the high aligned to give a flow from the SW and temperatures a couple of degrees higher as a consequence.


One thing is about as certain as model watching ever can be and that is that this pattern won't have shifted in any significant way in the next week.  I would put the odds on any significant pattern change before Xmas, i.e. getting a trough into Europe and pressure rising to our west or north, at about 10% based on the current output and trends (which are all the wrong way).

I think we can start to write off December. Output is poor for cold and it ain't going to change any time soon. All the early promise has disappeared it's looking like a old school 90s winter.

The output is as poor as anything I've seen since early 2007....  but then again, 2013 was the year that bucked the trend and dropped northern blocking tendency of previous summers.... it seems that's just continuing (for the time being at any rate) as we head towards 2014.

I don't think the pattern is 'locked in for winter' but I'd give you very good odds if you think anything resembling late December 1962 will appear in the next 3 weeks.....


Much as I'd love to be wrong.

Interesting that you say that, because sometimes I wonder what that cold winter would have looked like in terms of the forecast models (although the science has moved on hugely since then).  If you run the 62/63 winter sequence there were quite a few occasions when you would have put money on a breakdown but it never came, although it was close on several occasions.


As Martin said earlier the problem is the jet alignment - and those upper heights to our south/south east.  All that has happened lately is that the heights have displaced south briefly and then rolled back.


We need to see a drop of 50-60 dam in the 500hPa thickness over the continent and a similar shift the other way to our north - and that's a very major pattern shift.

More positively, the general model outlook for a fairly long fetch southerly, the result of Atlantic low pushing up against a north Europe high, bears a resemblance to the pattern which occurred shortly before the big Winter of 78/79.


 


But all this shows really is just how utterly random and chaotic weather patterns are.

UKMO offers a negatively tilted Atlantic trough. That really is as good as we have to work with right now. Considerably more potential than GFS' version, though.

It's really not happening for either camp is it?
Days and days of fairly benign, often cool but never very mild or cold weather to come.
Maybe the odd local spot in the northeast touching a 12 or 13; maybe the odd coldspot in the southeast catching a frost or two.

Looks set in until the week before Christmas perhaps.

With each run the AO becomes more negative, the heights become higher and the surface high is positioned more favouribly. No where near as good as the previous bering high, but things are starting to look very interesting now. A few more upgrades and I might be talking about a pattern switch after mid month.

This time, its a little different, the WAA is much less strong, and is tending to stagnate over E eurasia rather than make any progress towards the north pole or the central arctic. However there are some decent attempts to get height rises going over the arctic ocean, but the pattern is not consistant like it was last time. I can see hints of the jet stream trying to dive south over russia and some of the PV being taken along with it, that would really amplify the high on our side of the atlantic. The issue I have is the most natural solutions is for everything to be taken into canada again, or it to go directly into Europe and just end up a Euro high or something. Still, ECM will be interesting.
