  1. Morning all Cold still on the way,uncertainty on how long it will last but that is always the case. GFS op run a mild outlier in the later stages,majority ensembles showing cold. We've seen the models deviate run to run when there is a major pattern change afoot in the past. ECM looks to me like it couild deliver a true scandi high.the high doesn't to me look like toppling.-10 upper air temps on its last frame. The trend is still for a much colder pattern.
  2. Morning all, Are we now seeing the stubborn low heights circa Greenland being removed with something more conducive to cold for the UK?, Z500 anomolys seem to think so, Starting chart ECM Day nine GFS start Day nine Further down we can see more signs from the surface pressure, GFS day ten ECM day ten, GFS ensembles on the slide,
  3. Morning all, Middle strat temp now running well above the mean,not sure how long it will stay there, It'll be interesting to see if we get any trop response further down the line.Ensembles have been sniffing a change for quite a few runs 0z indicative,
  4. Morning all, IMHO we can never rule out a cold outbreak regardless of what the NWP show,many a cold spell has cropped up at short notice take this one for instance a seemingly dire chart below, Fast forward ten days to this, Aythings possible. The strats warming as we speak,
  5. Morning all, All models in agreement then,a period of zonality set to take over.I wouldn't be too bullish over how long it will last though and definatly wont be righting off the rest of this month that is just plain ridiculous,weve seen cold modelled at relatively short notice and out of the blue in the past and with the current pattern I see no reason why this isn't still the possible.One or two posters comparing similarities with this year and last,sorry but I just don't see them,the zonal flow last year was a lot stronger.This year IMBY weve seen five days of lying snow and recorded 10 air frosts since the start of December I think that by far exceeds last years winter total already.
  6. Morning all, It seems our chance of a pressure rise circa Greenland has now passed,even with the trop vortex relaxing around Baffin low heights have still scuppered any WAA from Atlantic ridging.Indeed current NWP are now pointing towards a rejuvenated trop vortex emerging in the Greenland area around the new year, with current output I would think our best chance of achieving heights that will bring cold to the UK would now be from our N/E,as I think this can be achieved whilst we have a strong trop vortex to the N/W.We have also seen heights low around the Alutians so far this winter and the snow advancement over Russia we saw in October would I think correlate to us seeing the return of the Russian high at some point this winter. ECM tries to rise pressure into Scandi around the 29th and we see a link up with the Russian high, Its something I'll be looking out for wether it materializes is a different matter. Merry Christmas to you all, Wolvesfan
  7. Morning again, One thing clear from the ensembles the operational run from the GFS was one of the milder solutions,
  8. Morning all, GFS operational looks an outlier and propbably one of the milder (wrong)solutions, Last nights 18z also an outlier as can be seen from the ensemble most runs below average 850 temps, Gem still looking cold for cold, UK met agrees, So does ECM, ECM,GEM go on to build stronger blocks circa Greenland,
  9. Evening all, Made the mistake of coming in here tonight before I viewed the output,heres what I found when I went and looked for myself, All the above showing cold for the big day. Great potential going forward too.
  10. Evening all, Lots of talk regarding the Azores being a winter spoiler.Could be quite the opposite though as we can see from these three epic charts below, WAA from the Azores fuelled the above.We wont get a sustained HLB without it.
  11. Afternoon all, Lots of speculation of what's going to happen out into the low resolution of the various model runs.The hear and now of the situation is that its cold and if you don't believe me go for a walk and see for yourself,todays temps, 60mph N/W gusts and we have a significant wind chill. Modeling looks good for cold in the high res part,GFS indicative, Still looks great out to next Wednesday, After that take with a pinch of salt.
  12. Morning all. Its nice to see something more seasonal has arrived,Tomorrows chart indicative, Cant say I'm too despondant going forward either.Hemisphericaly GFS in particular shows the heights which have been persistently low circa Baffin Island begin to drain and the residule energy eventually pushed to the Siberian sector. Week three looks good to me for potential although here on the ground we might have to suffer a while before we get what we want.

  14. Morning all, Looking odds on for a return of a more mobile flow for the UK.All models showing the retreat of the Scandi/Russian block allowing progression of fronts into the uk,angle of entry looks good as others have stated with a constant spew of low pressure sytems from the Baffin Island vortex,N/W S/E angled as highlighted below, ECM GFS, Temperaturs also dropping as wind swings into the N/W and taps into colder air, Jet stream also picking up sum intensity, Looks like after this weekend nothing mild on offer but plenty of cold wet and windy weather as we head into December.
  15. Morning all, My knowledge is limited compared to the majority on here.I cant see any cold whilst we have high pressure as such over Europe though,sceuro highs seem give nothing but mild for the uk we need some lower heights digging in.Heres a chart I hope doesn't verify, It will help with the strat vortex over Siberia only if it destroys it totally and dosnt relocate it closer to us. I'd sooner see warmth over the states because that lobe over the Baffin island area looks a lot less intense to me.Surely the Siberian vortex is better where it is?.
