Many thanks to all posters of output on here. All read daily to glean the knowledge. Gibby's Site in particular as so local. Well done Martin and look forward to another year of posts. ...  Happy New Prospects to all....

Shannon Entropy from end of next week falls to almost record-low levels, thereby exhibiting high confidence in the mostly westerly (and mostly cyclonic) story until end of 10-15d trend period, at least. More north of west bias by end, signalling drop in temperatures (unknown how pronounced).

In meteorological terms, I guess this is because the temperature contrast between the mid latitudes and the high northern latitudes is at its highest at this time of year, thus firing up the jet across the north Atlantic which blows wet and mild across the dastardly North Atlantic Drift, which is purposely designed to deny these islands decent winter weather.


That is why our best hope is an early SSW, whatever the sceptics might say, since that is the best chance of disrupting the standard, relentless west to east jet which powers in our direction.


The lack of Shannon Entropy identified by IF is particularly depressing, since it indicates high confidence in the current, rotten model output - it was ever thus!

Happy New Year all.
Taken from Martin's (Gibby) summary above, until this changes I cannot see any chance of a cold spell for us.


THE JET STREAM ENSEMBLE FORECAST(18z) The Jet Stream Forecast shows little change from that of recent output, remaining flowing in a relatively flat pattern West to East across the UK or close to the South between Low pressure to the North and NW and High pressure in a belt from Southern Europe and the Azores.

There is a ridge to the west but it's a feeble, very weak affair - the chart itself is very zonal still. Even if that were to come off, we'd still be a long way away from a proper cold spell.


EDIT: And looking at the EPS plume for London:


http://www.weathercast.co.uk/services/ensemble-forecast.html?eps=london


we see that 3 of the 51 runs bring a decent cold spell to London. The other 48 seem to show the typical out-of-sync sine wave pattern that heralds zonality...

Confidence levels high in the mid term outlook as I think has been noted:


GFS and GFSP 6z +180 hours


 


GFS and GFSP 6z +384 hours


 


Personally I wouldn't even bother worrying about the details on these charts. The general pattern is clear with a broadly westerly mobile flow persisting.


The best advice for most people here is probably to either start looking at the nuances of the set up which could bring stormy conditions and heavy rain at times with the risk of more wintry conditions over higher ground in the north, or to find something more productive to do with your spare time if snow is your only weather interest. Just looking for snow at the moment is bad for your health!

I've booked flights to a place gauranteed to have snow, for example, although I'll have to wait until May to see it! Hopefully there'll be some here before then...

As several here have been saying repeatedly for a week at least, there is no sign of anything generally wintry on the horizon until mid January at least, and maybe beyond.
As Lord Sugar would say, the wait continues . . .

If this chart output is anything to go by (I got it from Gusty and now use it to have a quick glance in the medium range output without trawling through lots of graphics), http://wxweb.meteostar.com/sample/sample.shtml?text=EGMD, at least it does seem flooding is quite unlikely to be an issue for this end of the woods despite the seemingly changeable and breezy outlook - a subtle difference on this time last year and proves how that Azores ridge is nearer than we think.

I suspect Scotland and western parts of the UK won't fare quite so well, though.

Hi Doc! Indeed, I think due to the very westerly component about things, the lee effect is going to be in play over the UK over the next few days, especially if the higher heights stay close off to our south.

Poor outlook for coldies at the moment. Awful, just awful.
However I'm hoping to see signals of a Greenland pressure rise in the far reaches of FI in the coming days.

While it's by no means certain that the stratospheric warming that is seemingly taking place right now will be of any benefit to us in terms of getting us out of the current zonal pattern, IMO it does give us half a chance. Any SSW that occurred last winter either wasn't strong enough to change the pattern, didn't occur in an area that was of any help to us, or perhaps both.

As ever it comes down to personal taste. FWIW I think the current outlook is potentially worse than at this time last year. Quite a lot of the GEFS Ps are showing a zonal Bartlett developing during the first half of January. They're available on the chart viewer and to be blunt a lot of them would hold their own against the horror shows frequently on display in the 90s and 00s:


http://www.theweatheroutlook.com/twodata/datmdlout.aspx


Each to their own, but I'd sooner have more mobility across the south if we can't have cold and snow. The zonal Bartlett takes the gold medal for the most boring winter pattern in the UK.

Last year despite a promising looking strat warming picture there were just far too many other factors going against a colder pattern developing. The North aligned jet was in turbo mode and the Atlantic was a perfect breeding ground for UK-bound storm systems. 


Things look different this year. Not necessarily better at this point but certainly different.

I'm afraid it does nothing for me. This Azores High is a real pain in the arse this Winter so far.

ECM mean day 8



12z op continues the theme. You couldn't draw a more unfathomably bad winter chart.

I fear GFS might be into something here with its mega zonal Bartlett.

So far this winter GFS has been miles ahead of ECM in the crucial 6-10 day period.

Actually the above chart is worse than 1989, at least 1989 was benign with mostly light winds and bright skies, I remember one Sunday in that month going to the beach at Torquay and it felt like spring. If it's going to be mild it might as well be very mild!

What we don't want is another winter like last year.

At least it's January now with just two months till spring and I think when that time comes we will be glad of it!

Although the downside I suppose is stormier and wetter weather with a risk of flooding. GFSP is very wet.
