    Is the cloud one right (assuming white is "cloudy")? I'd be surprised to see sunshine in Cornwall in that setup, and conversely I'd expect much clearer weather in Scotland north of the front.

    It is yeah - in this particular instance it just appears to be a well defined frontal boundary with high pressure to the south keeping things mainly clear. As is always the case with weather, different every time...

    Mind you with the wind direction the way it is, I suspect there will be much low cloud, plus drizzle on windward coasts - so when it comes to light levels, it'll arguably be absolute winter. Or perhaps like late October or early November minus the leaves. Probably exceedingly humid also.

    For me (and I am someone who is looking forward to lighter days and dislikes the overly-early sunsets of winter) those charts couldn't be worse. I'd honestly prefer a named storm and a low right over the UK if only there might be a N-ly in its wake!

    Scotland looks OK though, in much clearer and brighter Pm air by the looks of things.

     

    Probably more of a selfish thing for me - over here in the east we get sheltered from the worst effects of westerly/SW airstreams, most of the ppn tends to get dropped out to the W/NW, and we can miss the cloud altogether. The chart below shows 16c and sunny despite the westerly flow. That'd feel dreamy to me.

  3. Nice to see a summer thread appearing....winter officially only has 5 weeks left before we can wave goodbye for another 8 months or so.

    Can't wait until the light properly returns and all of the flowers and trees start to bloom with the birds singing away on a sunny spring morning. Better than everything looking desolate and dead as it always does in the middle of winter. 

    What will Summer 2024 hold? As long as we get a few decent weeks out of the season then we're ok. I'm not expecting another 2018 job. 2023 was odd with a nice June, bad July and August, then the scorching September.

  4. Why are people in the middle of the country surprised there isn't strong wind? It was never going to be really windy here. Gusts of 10-20mph this morning, relatively calm.

    The strong winds are all on the southern flank of the low, as was always the case. As it moves north through today, winds will pick up to 40-50mph  across central areas, but you aren't going to see anything too untoward.

    I don't think anyone is tbh, 

    There were loads of people in summer swooning about how great autumn is.

    Well to me, when I think of autumn, this is exactly the sort of weather that I associate with it. Wet, windy, miserable. You can get the nice calm and mellow days, but they are sadly vastly outweighed by this absolute tosh we have to contend with.

    Beautiful out there, the sky today is a really clear blue. 24c, a few 25c's now showing up in Essex and Kent. 

    Yes - Cavendish has been above 25c for 3/4 days in a row now. Certainly be a shock by the end of the weekend when we are down to 12c!

    Well, it's a long way off, so really just for fun, but you never know...

    You clearly like the warmer stuff like myself...we may squeeze one more very warm day out in our neck of the woods on Friday.

    Beyond that - the first widespread cold nights of the season could be with us in a week. Temps around freezing or just above in  most areas by next Sunday night on the ECM.

    546dm thickness well to the north of Scotland.

    564dm line (Tropical air thickness) still across Southern England.

    Also, that front looks like it's occluding rather than a straight forward cold front.

    Was just going to say the same....you do realise that is the 564 dam line straddling the country in the second week of October?! 😆

    Those auto generated temps are always a bit off anyway. The UKV run has 24-25c in the SE Monday, ARPEGE 26c. 22c may be a bit low.

    There isn’t a single model showing this warm spell ‘teetering on the edge’ this weekend. All have extended into next week. What an odd comment.

    The only real wobble this morning is the GFS, which shows only 18/19c on Sunday.....which is at odds with other output. UKV for example has 24c on Sunday, and up to 25/26c on Monday. As you say though, it does keep temps into the 20s right out until Wednesday.

    A question: whyare upper temperatures of 20C only translating to 26C / 27C? I know it's October, but you'd expect a bit more than that. Even in Paris, it's only showing 27C.

    29.9c was achieved under this set up on October 1st 2011 at Gravesend.

    If you look at the forecast for Saturday, you'd think that with a much warmer airmass we'd be seeing similar temperatures. Airmass just probably isn't dry enough this time around with more of a SW component. Makes all the difference with lapse rates etc. Humidity is still above 50% in most of the SE.

    The gfs forecast sounding for Saturday is a quite a good illustration of why surface temps, based on the 850mb temp, can be a tad tricky if the lapse rate in the boundary layer is modified by such as cloud, etc

    Looks pretty clear to me on Saturday at least going by the GFS. The obvious limiting factor is the fact that it's October, not July, and not a straight southerly flow. 25/26c seems fair. Sunday on the GFS has more medium and high level cloud in places, but at this range purely speculation.

  13. Although Autumn can never really be Summer as we lose the long days.....this year really has tried its best to make up for the dreadful July and August. An exceptional September followed by a really good start to October. It'll end at some point, but at this point I'm just drinking it in. The prospect of 25c next weekend, wearing shorts and a BBQ or a trip to the coast fills me with joy. 😎
