    I admit this is a bit out of date but I just love different shades of blue when it comes to T850’s (uppers)!....perhaps the early part of winter will be interesting from a cold perspective if the cfs is on to something rather than just on something?😜🤪

    Good evening! 😀 1st ever post! 1st of many I hope. Love this forum.   ECM: Tonight Matthew, I’m going to be... The GFS from yesterday!     A real tease, shame the OP only

    ECM indicating a return to some settled weather end of next week however a few showers & the flow becoming Northerly so the potential for some frost developing- Nice & seasonal.

    And with the GFS 12Z at T+384, I think I'll pop to B&M and buy me a small fan-heater... Hopefully, I'll run into Miss Tiggywinkle while I'm at it. And maybe get the gen on the upcoming winter!🦔

    Another set of dull as dishwater 12z runs so far. Come back tomorrow and see if anything has changed.

    Ensembles staying well above average still. A few stray colder runs, but nothing more than that at the moment.

    A coldie in the u k needs a sense of humour, after all we are not lucky enough to be in Canada or Finland for example..actually, the GEFS 12z doesn’t turn out too be a complete mild fest as these charts would suggest!?...I will keep looking for some major cold (don’t laugh!🤪)...it’s still autumn for another 3 weeks and a bit!😜

    This month (looking at the latest 12z and others) looks very reminiscent of December 2015 with the jet dipping south eastwards in the Atlantic only to buckle northwards to our west leaving us in constantly in mild/warm air...as long as we stay dry.

    35dayer from GEFS suite is promising for more seasonal temps down the line but a lot can change before now and early December

    Today's D10 charts on the ECM and GFS very similar in synoptic:

    ECM1-240.thumb.gif.0c9dfeab0c18b6b1bbddb55c9dce6334.gifgfs-0-240.thumb.png.3f3466dfd09ea2830adb774c1b66d106.png

    This a repeating pattern from earlier this month that never quite married up to what we got:

    Nov 1 chart from ECM for Nov 5 and Nov 11:

    ECM1-120.thumb.gif.987c8f9dbc04ac44b6defebe0159971a.gif1024105009_ECM1-240(1).thumb.gif.c0f56b1a49ab6a1fdf5c930280703b7e.gif

    Current chart for Nov 11:

    gfs-0-84.thumb.png.3250f74c9908f24c7246a1df9d1c703d.png

    So this morning's charts although promising a last hurrah for Summer are relying on the algorithms working out that cut-off upper-low again? I will be interested to see how the models handle it on this occasion. If there is a ghost in the machine, where even at 5-day it can be wrong, then noteworthy for our sanity going forward.

    FWIW this morning's 0z from the GFS went on to...

    The only crumb of comfort this morning is that the GFS op 850s wise was very much on the milder side of the esembles later on.

    Looking or trying to be positive can this upcoming winter be any worse than last year. I'd suspect not so. Looking very stagnent at the moment but hope springs eternel. So il now go and store my industrial box of straws in advance for the coming  days 🙏🙏

    A quick question over those charts. Everytime I look at them those green contour lines seem, to me anyway, showing the exact same thing whether in summer or winter. Probably the mind playing tricks but what will it take for them to show a NE'ly

    [b]What I don't understand about them is that they show a high anomaly which, in that chart you've posted, would suggest a Southerly or Se'ly rather than a SW'ly and that contradicts the green contour lines which are in a seemingly permanent SW'ly[/b]

    Honest question - I'm not trying to dismiss that model just trying to understand them more

    I think i can explain this a bit better now.

    These two fax charts for today and tuesday demonstrate the BIB.

    The green contour lines then showed a gentle southwesterly, and this is borne out on the current fax charts which illustrates the Northeastward progression of the messy shallow lows and attendant fronts off Biscay.

    We dont get much of a Southerly or Southeasterly because whilst high pressure is centred to our East/northeast, it also ridges southward so theres little continental element, or not strong.

    These charts IMHO are completely in line with what the NOAA charts were predicting.

    Edit...oh you dont do a BIB now?

    Truth be told there still isn’t anything to whet the appetite in any of the output yet. There’s still a chance it turns colder in the last week of November, but equally we still have ensemble members showing the mild weather continuing. It’ll probably take a few more days to sort out, early to mid next week looks complicated with a possible split flow developing.
