    I must be the only one then that looks at these chart and walks off satisfied. Anyone hunting wall to wall snow in November needs to read their history. The pressure differential between Greenland and Scandy on those charts is pretty good for vortex disruption when combined with the Aleutian low in the North Pacific. November is nothing but a setup month - no low ground product in terms of snow is realistic. In addition the pattern is effectively blocked, and people need to realise that a block creates a more meridional flow that promotes warm flows from the south as well as cold flows from the north. The fact that the Scandy anomaly helps pull warm air up over the UK is part of life in this part of the world at this time of the year. The pattern is not one of raging zonality, the strat/trop disconnect remains in place at least for now, and vortex stress looks likely. Winter doesn’t start for 3 more weeks, and realistically doesn’t really kick in until mid December which is 5 more weeks. If you need to cheer yourself up in the search for snow try reading up about the Feb 18 reversal that led to that beastly spell. The Atlantic preconditions are not dissimilar and while every patten is unique we are certainly in with a chance of a cold outbreak this season. Just don’t expect it in November and don’t expect it to last all winter. 1963 was unique and a year I don’t think we will see repeated for as long as the world continues to warm.

    Good to see things ticking along nicely WRT pressure rising to the North & the atlantic systems being ushered on a more southerly track- Some may remember me commenting 2 days ago on the GFS being to far NE with its angle Well now look V the 2 charts from the other day Original prognosis at 84 was all the enery moving NE Now the same timestamp this eve on the 18z Note the swift change to the jet alligning SE This will stop the low ploughing NE through the UK which would have blocked the small ridge of high pressure moving NW towards Iceland- Now this ridge looks like developing so the return to colder runs has returned At this point in the year im glad the main thrust of cold is still 8-10 days away as for us down south thats really the earliest window we could really hope for snow anyway.... First Air frost here last night @ -0.5c Cheers

    @Allseasons-si A classic 3 wave pattern. Anyway I think the key watch here over the next 14 days appears to be the amount of 'undercutting' we get from a high that aligns NW up towards Greenland... Very very interesting times - Early snow potential available for the North...

    Once again some great and insightful posts, sorry about running out of likes! The 12z ensembles to me look just fab, the mean has come down further, and we are now looking at a fair amount of sub zero runs, I've even noticed a few potential snow makers on a couple of em. It's blatantly obvious things are shaping up well at the moment due to the increase in posts. This could be one hell of a busy run up to Xmas and beyond. 2010 repeat!! Let's go one better and have a 47/63 combined effort.... Could we cope with that! I'd like to think so.

    The usual (probably quite dull by now) advice from me We should not be too quick to dismiss a single deterministic run, even if it is out of kilter with its own suite (caveat: I have not yet seen the EPS suite), particularly given the higher resolution of the deterministic run in trying to resolve some delicate balances over the atlantic. We simply don’t know at this stage where to judge this run and will need to wait for further runs. My second and definitely tiresome piece of advice is to be very cautious when looking beyond day 5 in the Greenland locale and particularly with regards to any suggestion of increased heights (those lovely greens and yellows on the H500 charts) - we have seen season after season a bias towards increasing heights too much in this area beyond day 5, only for this to correct itself the closer to T+0 we get. At some point, like a stopped clock, the models will sniff out one of these Greenland height rises correctly (and I do fancy that to be this year incidentally), but for now I would urge caution before we drive ourselves towards an early season meltdown. With Brexit coming Nick might struggle to get the Prozac over the border.

    18z says no to phasing the lows. This really is not your standard Northern Hemisphere . Whether we end up with a proper cold spell by the end of the year or not, this will continue to be fascinating to see this continue to evolve over the coming weeks

    It's great to see all the gang back on the strat thread - I did nag @chionomaniac to join in the fun. @Recretosgreat blog on Severe EU and always love seeing what data crunching . RAM abusing graphics are up next. @zdlawrence prettty much a privilege to have you here Zac, your website is a real benchmark for Strat monitoring after years of peering at the Berlin charts. I think the testament is that even a year on the 3D work is catching the attention of esteemed pros such as Mike Ventrice. I loved the fact that #stratpants appeared this season when last year we had saw the same split troosers ( Scottish for Jeans / Trousers / etc). Best contribute with some commentary too other than say what a great season ahead, am personally loving Novembers now - it's the chase of the what happens next as much as the will it won't it herald negative AO/NAO or a decent winter.. By that I mean the down-welling question and the concentration of minds on this. Stop and reflect for a moment on how we were only 5 years ago working out precursors or Displacement / Split Dynamics.. Loving this ! Gnarly old vortex aint enjoying the Anticyclonic stuff happening right now.. can't do what it wants... Get your crayons out... Not a forecast there are two other years in the mix for Solar QBO similarity...however 95 worth a look..

    I agree that we weren’t lucky last year. We got about 85% of the way towards the cold blast the models kept seeing, but the split ended up being a bit too far west, and SSTs in the Atlantic conspired with the very cold air spilling out of America to prevent sub tropical ridging on the back of some solid tropical forcing to create the high lat block. I think it was a very fine balanced thing...and we got close but not close enough to tip that balance in favour of cold. I don’t see our current kind of mobility in November as a bad thing at all. For a start it isn’t conventional mild zonality - the trough over Europe is helping keepthe trajectory of the Atlantic assault quite steep with residual heights to the north remaining in play, and we have heights to the east in the right place to upset the vortex. Over on the other side of the globe the North Pacific ridge is set to topple, and a period of Aleutian Low action will also help fire warmth into the vortex. Later in the season what we need is a block to the north/NW/NE that can cause a reverse flow and bring in continental cold and this is very hard to achieve when the vortex dominates. So all remains good as far as I can see, and anyone hopeful of widespread snow right now is hoping for the near impossible. Perfect Synoptics right now in most places would bring nothing but drab, cold rain....so let’s “enjoy” the current setup that is about as good as it could be to set the vortex up for a fall and create the background conditions that could bring something special when winter proper is here.

    It doesn't seem logical take to take the 0600 out of context with the previous two runs and the the ecm After all it was only the other day when you stated 'bin the 0600' because it didn't agree with your preferred outcome.

    Not sure it’s worth taking the current outputs at face value in terms of precise detail , better to look at the overall NH picture which is positive for coldies . The overnight ECM is a big improvement in terms of reducing the strength of the PV and moving it further to the nw. I’d give it a few days to see where the pieces might fall. Writing off mid November cold at this point seems very premature .

    EC46 not too different from the ext EPS knocker posted earlier on. Heights generally to the N/NE with temperatures below average for the first part of November Blocking relaxes during the second half but interestingly a signal for blocking to the east returns during December, though little point worrying that far ahead at this stage.

    SSW in Dec as a whole I think could be considered rare given that is the canonical Vortex Intensification period, happy to be challenged on that view however.. I think without pulling out any papers that statistically January is your go to month for SSW with December being very much the exception, still gobsmacked by the EC Seasonal update to be honest - the plot for December shows an SSW with the Ensembles posted earlier showing the cluster heading that way. Then, January plot is also a torched vortex, if that came to pass then we are in for a ride this winter. What is also interesting is that this November feels like a throw back to when Novembers featured Canadian Warmings back at the start of the 80s, given last November saw considered action also, just a few years ago we were wondering about whether Canadian warmings were actually worthy of classification, or a nuance of the early satellite era capturing more detail and then requiring classification of a kind. Rambling now... onwards and upwards with the wave breaking !

    Morning all . Woke up to a nice covering of fresh snow. The fine mesh model we use forecast 20cm at our location with-in 2 Sq M perimeter and guess what ? Spot on. Just blows me away with the numerical accuracy at that range. A great tool for the resort planners. The winterview chart below from CDPS model seems to continue the rather cold unsettled spell over much of NW Europe at 144t with further snowfall over the Alps and increasingly so over upland Northern Britain. There appears some uncertainty at this range from this mornings big main models. Both GFS and ECM seem to water down the prospects of a developing Scandinavian with a shift to a more Northerly flow and mid- Atlantic ridging but the British Isles remains in the cold side of the trough throughout. Will get the views of the team with regards to their own medium longer term outlook. In the meanwhile just received latest snowfall portal service report and that's for 30cm more snowfall before the end of Sunday. C

    FWIW the JMA probably the most likely to deliver a flake or two, or maybe more, here at T192: Didn't know JMA did strat charts, but some forcing on the vortex as early as T192: Very interesting to read @Tamara thoughts above. Couple of thoughts, re the idea of lower AAM as per La Niña atmospheric setup, could the Indian Ocean Dipole as mentioned as a reason for the +NAO forecast in the MO contingency planners forecast, be contributing factor here? A strongly positive IOD adds easterly winds at the equator, so seems to support. (Usual caveat, I can't claim to fully understand this area so maybe barking up wrong tree!) Second thought, like I was saying the other day when a new probabilistic model shows results that echoes the others, it doesn't actually change the probability of cold or mild, I think most of us now have factored in that there is a certain weight of evidence against a cold winter, Tamara's post backs that up. However, in my mind, weight must be given also to the arguments about what is seen here and now in models regarding both the trop and strat, and persistence of a -NAO regime, and the extreme solar minimum, which I believe the science is lacking a bit on. If the coldies get nothing this year i.e a 2013/14, I will eat my pants. But the fact that we're up against it, makes the jackpot sweeter when it lands! Going to be great model watching as winter proper is now fast approaching...

    The North Atlantic surface analysis and the 0400 UK chart and 0300 WV image The deepening low is in the process of crossing the country through today resulting in bands of heavy rain associated with the fronts in the circulation effecting some areas. In particular Wales, the south west and northern Scotland and this will be accompanied by strong winds particularly in the south west and along the southern coast. Suffice it to say already gusts of 50kts down here. Overnight the low is now centred in the North Sea so a continuation of the rain belts running around within the circulation and still mainly effecting Wales, the south west and eastern Scotland A not dissimilar story on Sunday as low low slowly fills so a day of sunny intervals, heavy showers and longer periods of rain but the winds should be decreasing. But further troughs have joined from the west and the eastern Atlantic is now a very complex area of low pressure Over Sunday night through Monday the filling low is absorbed into another low within this complex trough which is now becoming positively tilted courtesy of the subtropical high temporarily amplifying in the west. Thus another day of sunny intervals, heavy showers and longer periods of rain and the orientation adjustment has introduced a cooler north easterly wind in the north By Tuesday the north easterly wind prevails over much of the country so generally a drier and cooler day but the remnants of the low are still effecting the south east so cloudy with some rain here. But note the ridge is under pressure in the west After a frosty start Wednesday should be sunny for most but further troughs have suppressed the ridge and made inroads from the west and the associated occlusion will bring rain the western regions in the latter part of the day which could fall as snow over the high ground in the north now that the colder air has been introduced

    The North Atlantic 300mb wind field and surface analysis for midnight Area of rain, currently aligned across the north of England is at last easing and starting to fragment and this will continue through the day, perhaps even giving some sunny interval by the afternoon. But showers will continue to feed into north easterly and westerly coastal regions as well as northern Scotland. By late afternoon more persistent rain will effect the south east courtesy of a shallow low This rain will track north west though this evening and overnight but remaining clear over N. Ireland and Scotland with a frost by morning Still some patchy rain around on Saturday, mainly in southern Scotland and northern England but generally a better day with sunny intervals but an occlusion is slowly approaching Ireland. Perhaps a tad warmer By Sunday another intense extra tropical cyclone is tracking towards Greenland promoting some downstream ridging resulting in pretty static showery day over the UK On Monday the low is filling and moving east across the Atlantic and after early patchy rain in the south east it will be a sunny and cold day in the UK after a widespread frost. By Tuesday the filling and complex low is dominating the area west/south west of the UK and by late afternoon the associated occlusion will bring heavy rain to N. Ireland and the south west. Elsewhere it will be generally sunny but cold after a widespread early frost

    I agree with @s4lancia from my POV and as I posted last night still every chance we could get an easterly flow and actually the 06z GEFS were better < those are the perfect setup for snow streamers here. Again the focus is on the position of the lower pressure if it is to the S / SW of the UK we will have a good chance of getting the easterly, if it moves N / NW over the UK that will ruin the chance. Still all to play for and even if we dont end up getting the easterly we are only in November so anything wintry at this stage is a bonus and we still have the possible effects from the stratospheric developments with zonal winds getting ready to decrease and still signs of warming (how significant still to be resolved) . Also how often in the past have we went from A - B into colder weather without the usual upgrades / downgrades cycle - example from Jan 2009 days before the famous Feb 2nd 2009 event in the SE GFS 0Z 27th Jan GFS 12z 27th Jan GFS 18Z 27th Jan GFS 0z 28th Jan Actual charts Even just 5/6 days before there was lots of chopping and changing of the position of the cold pool so how people can take the exact positions of the setup for a week from now is beyond me, with the memories of last winters failed easterly I would agree that a cautions approach is needed but remember that the models have the tendency to underestimate blocking areas of high pressure...

    I'm not going to get into a war of words with fellow posters on here regarding early cold chances, firstly there are a dam sight lot more knowledgeable than me for one. Secondly its far to early to be worrying about just where exactly heights are going to be setting up, or not setting up at this stage! A cold shot looks plausible next week!!!snow for some even!!! That would indicate to me, an early taste of winter! But in all honesty we need to fast forward another 4-6 weeks before we can start making sweeping judgement on early winter!! No need for anyone to take a break from model watching at this early stage folks... Let's sit back, relax, and let it unwind!!! And breath!! And the 6z ensembles weren't a write off by any means... Still plenty of colder options on the table.... Its all good. ps the op lost the plot at times towards the end of the run... No surprises there then.

    Morning. Using the Gfs and Gem mainly for this update.. So a snapshot below 3 timestamps.. GFS for Friday.. Sunday 24th.. Tuesday 26th.. Friday 29th.. Finally 1st December unreliable time frame but shows a classic vigorous low pressure system pushing quickly northeast across the north Atlantic grazing Scotland and sending an active cold front towards the UK with gales for the far northwest of Scotland and Northern Ireland.. An impressive Wind gust chart.. Now the Gem.. Friday 22nd.. Sunday 24th.. Sunday evening.. Tuesday 26th.. Friday 29th.. If we blend Ecmwf the Gem and Gfs average output together this is the synoptics shown.. Monday 25th.. Friday 29th.. Good agreement for southerly tracking low pressure systems bringing plenty of rain with a risk.. only a risk at this stage of a particular spell of very strong winds for more southern areas towards the end of the month but uncertainty as expected.. Higher pressure towards Greenland and a displaced Azores high keep the unsettled conditions locked further south than would typically be expected. So Gfs for the next few days out to around a week in more detail.. Continuing drier than recently for most parts of the UK the exception being the far southwest of England and Wales with rain effecting here and perhaps fringing into Scotland later today for a time with a frontal system stalled out to the far west this is expected to push back further west into Ireland by tomorrow evening as high pressure over the continent exerts more influence.. What this does is strengthen southerly winds.. This evening and tomorrow.. Thursday winds turn more to the southeast as the rain out west pushes slowly northeast later in the day with the blocking high to the east of the UK allowing this rain to make more progress. dry to start though for northern and Eastern areas.. Into Friday the band of rain becomes confined to Scotland and northeast England elsewhere turning mostly dry with sunny spells and milder than recently as winds blow from the south the winds then start to turn to the southeast again as the centre of low pressure slips southeast as it isn't able to push into the north sea and fills because of the blocking high out east still has enough of an influence to deflect this to the south like I mentioned..what this process does do is push an area of rain back northwest to southwest England later in the day.. Friday morning and Friday night.. Saturday morning more rain pushes up from the south giving a very wet day to England and Wales drier for Scotland and Northern Ireland for a time.. Saturday night the rain becomes confined to Eastern Scotland turning dry elsewhere.. The centre of low pressure fills to the south as shown below.. Sunday night into Monday morning on the image below a very active frontal band of rain pushes into much of the west of the UK the stubborn high pressure to the east of the UK has now eased away to allow this rain to push in with more momentum.. some of this rain shown to be very heavy particularly for the southwest of England even torrential locally and this then pushes fairly quickly northeast giving a very wet start to Monday windy too with this rain but then it turns much drier from the west with only a few showers still mild.. 25th.. Wind gusts.. Staying unsettled into next week potentially very windy for southern England during the middle of next week with yet more rain but drier spells too staying mild.. Remember this is just a snapshot of what the Gfs is showing the very wet conditions are likely but detail especially for next week is subject to change and shouldn't be taken too literally but it gives you a general idea of what conditions to expect.. 5 day maximum and minimum temperature expected over the next 5 days.. Mild by day and milder at night too after tonight's cold night which is responsible for why the 5 day minimum temperature is showing as low as near or around freezing and below for Scotland.

    Back to the present... Are we underestimating this storm tonight? Up to 90mph gusts on the EURO4 even in a couple of built up areas like S Wales. There could be quite a bit of disruption, but media surprisingly blase? This mean wind speed chart has F10, close to F11 approaching S Wales for first thing tomorrow - very dodgy indeed

    Yes, Matt Hugo mentions the same thing as Judah Cohen yesterday about whether the combination of aluetically low and scandi-high in mid-November can disrupt PV and possibly lead to an SSW subsequently, as it lies on each side of the Arctic. This is exactly what led to an early SSW in 2009/10. It is good that PV is stronger than normal, which can collect very cold in the upper stratosphere. If it is quickly attacked afterwards, an SSW allows to push very cold air away from the Arctic. Interesting things are already appearing in the PV forecasts despite the strengthening. In 2009, PV also strengthened first, while November transitioned from -NAO to neutral NAO. It provided high pressure over Scandinavia-Eurasian and the North Pacific, which weakened PV via energy transfer. We had a blockage in the troposphere and fast wave 1 and 2 activity. It reminds me this year? Solar minimum? And so I think everything continues to go against the season models until day 7-10. It is only afterwards that you constantly see the peak of PV in the forecasts, while it changes continuously for the first 10 days.

    Morning peeps! Plenty of scope for a seasonal start to November, with frost and fog looking evermore likely...And, frost-encrusted trees come a close second, to snow of course, at this time of year! And, the ensembles are now showing less scatter than they were so, hopefully, the models won't be too far off the mark...?

    The North Atlantic 300mb wind and surface analysis for midnight and the 0400 UK surface chart The key issue today is the broad area of heavy rain associated with the front that is currently aligned central Wales > Suffolk. This will pivot through the day to be roughly Humber > Devon by 1800 to bring persistent rain to the areas underneath and snow down to quite low levels south Wales and the west Midlands, Further north after a frosty start a pretty sunny day although showers along eastern coastal regions The area of rain will continue to pivot to some extent overnight with frequent showers along north east coastal regions in the north easterly wind which also means the dreaded Pembroke Dangler comes into play in the south west Cloud and patchy rain continuing in the south east on Friday but becoming heavy again through the afternoon as a wave develops on the trailing front. Showers still in the north east and the south west with north westerly regions drier and sunnier Cloud and patchy rain will continue to be a problem in the south east over Friday night and through Saturday and by dusk another waving front will bring rain to N. Ireland and NW Scotland. By Sunday there is another quite intense extra tropical cyclone near the tip of Greenland that promotes further downstream ridging resulting in the UK being in a very slack gradient with stalled and bits and pieces of fronts bringing some patchy rain to northern and eastern areas with snow on the high ground on a rather chilly day The low tracks east across the Atlantic on Monday but the eastbound energy hits the buffers of the block in the east resulting in th wave that has developed in Biscay tracking north east into the North Sea. Ergo not a bad day, albeit quite cold, in western and northern regions after a frosty start but some cloud and patchy rain may effect the south east and eastern regions

    Hmm - if we were heading for a +NAO driven first half this isn't what we would expect to see - but its still only the first half of November. If it looks like that for the 7 - 10 beyond then something may be brewing running in contrast to NWP outlooks. Wonder what Glosea might have in store in its next update...

    Masie just out. What can I say..... ESS 101K increase. Laptev 80K increase. I call that a flash freeze. We now have the imminent situation of the central ice pack linking to the Siberian coastal ice in ESS, as well as it has already achieved in Laptev. This leaves it more likely that more rapid ice gains will be made filling in the still open waters. Elsewhere Beaufort added +11k Km2, and Barents added +13K KM2. The ice pack is being pushed by the wind into these areas, with the ice around F.J. and Svalbard looking very menacing. Even Chukchi moved forward with +6K Km2, for the first time this year. Zoom in the charts below for detail. If further proof is needed of the rapid increase in sea ice, the time taken to get from 5000K to 6000K is now the second quickest in the last 10years, For example last year took 14 days as did 2015. Both years were considered quite a fast rate of increase - whereas it has taken just 9 days this year.

    Ive dismissed the ECM op for its progressive nature over the top of Greenland ( 168 > onwards ) NB same the other say- where it sweeps the high pressure aside from the west ... ECM mean looks much lower with better pressure over NW greenland, also the 192 mean a lot closer to GFS mean- ironically the swing to cold from ECM mean is almost identical to the GFS swing I posted earlier
