    You aren’t reading the hemispheric pattern because that’s precisely happening as we go forward.

    Not seeing much evidence for that personally, as any retrogression seems to coincide with a further build in pressure over the Azores / Iberia, which prevents a southerly undercutting jet.

    I think that HP centred over the Russia/Kazakhstan border is the key here. (In this scenario). I've seen this modelled previously. It forces the jet into Europe, the euro high retrogresses and the TPV is forced through the gap, pushing a big cold pool with it.

    Its a long way off but it's a plausible evolution.

  2. I always think, winter model watching is like watching England in the World Cup. 

    We go 1-0 up early on, then the opposition equalises in the second half. We get numerous chances and shots on goal, only for them to be saved or called offside. We then sit frustratingly through extra time, only to lose on penalties....

    Thankfully, we've had a lot more epic winters than we've won world cups so the chances are much higher... 

    "They think it's all over..." 

    Not yet....

    Look forward to seeing this evolve …

    So am I...

    I  (partly) agree with you regarding January, it's highly unlikely there will be anything particularly wintry for the next week or two but after that, some models are showing an evolution to more substantial winter weather. Even when the "building blocks" are in place, it's a fine balance to  hit the jackpot on our little island but we can never discount any chance of it happening.

    Just sensing this winter will keep us on our toes, whilst we maintain the strat / trop disconnect. As we saw over christmas there was major uncertainty how things may pan out, and I read not one forecast going for record mild temps to usher in the New Year. With this in mind, keep an open eye when viewing the models - expect sudden developments and departures from what any of the ensembles and anomalies show.

    In the meantime, within the reliable - about 120-144hrs tops, we have a chilly period ahead, more so further north, with snow to relatively low levels at times, wind and rain elsewhere and return of frost in clearer breaks. The models are hinting at possible height rises further towards the mid month period, but too far out to call what might happen.

    Those wanting something more notably colder and snowier, if such weather does happen, I suspect it will appear at very short notice, and catch us out this year.

     

    A point well made. 

    The disconnect is key here. Many people are noting the 'raging PV' which normally would keep us on the zonal train, (hence the despondency) we don't have a raging strat to match. Hence why the forecasts have gone down the toilet 

    Therefore anyone forecasting a dull rest of winter, don't be surprised if your toilet gets blocked by a snowmans poo ❄️⛄before winter is out.... :snowman-emoji:

    Read - unsure what signs you’re seeing (absolutely nothing across NWP supporting this at all). We all live in hope and I for one would enjoy nothing more than some cold and snowy weather but currently Jan prospects look extremely bleak. 

    Ok, not sure you've read my posts correctly, or maybe you've just missed the context. The point was, that January may look "bleak" but with a very similar hemispheric profile throughout January 1991, we entered February with one of the most epic cold spells in memory

  6. https://www.meteociel.fr/modeles/archives/archives.php?day=5&month=2&year=1991&hour=0&type=era&map=0&type=era&region=nh&mode=0I can't believe the negativity in here.

    What's being modelled is almost a 'copy and paste' of January 1991

    I'm certainly not writing anything off yet...
