This piqued my interest, the AC is generally > 0.9, but during the periods of lower predictability, is there a possible strat effect?

The impact seems more important if a greater depth of stratosphere is affected by vortex weakening than just considering the 10 mb level alone.

Certainly an interesting observation.

I guess the MetO updates through mid July which continually called for dry and warm weather have well and truly been wide of the mark. I'm not going to doubt the forecasters and data there, which far exceed my knowledge....but to myself and many on here, this outcome never really gained a massive head of steam did it? I'm just wondering what they can see (that we can't) which continually led to this forecast.

UK Outlook for Tuesday 25 Jul 2017 to Tuesday 8 Aug 2017:

More prolonged dry and warm spells may become more prevalent across much of the UK through the end of July, perhaps continuing through early August. The northwest is still likely to remain more changeable at first though, with a risk of gales in the far northwest. There may also be spells of rain or scattered thundery showers at times in the south. Temperatures will probably be above average generally.

      A busy spell coming up, as the beast from the east arrives.
      As the focus of the model thread is often a bit further ahead, for those wanting to talk more exclusively about the shorter term outputs, we do have a short-range thread up and running. (You're still welcome to discuss the shorter term in here too though).
      This thread is all about discussing the models - but we have loads of other options for other topics:
      As always, please keep it to the models in here, and head over to the banter thread for any moans, ramps and general chat.
      For threads related to the cold spell, met office forecasts, the winter overall and much more on top, please take a look at the general weather forum:
      https://www.netweather.tv/forum/forum/1-winter-and-general-weather-discussion/
      And finally, if you're wanting to chat about your local weather, the risk of snow in your particular location etc, then the regional threads are for you:

      Ooh yes, it's busy and with good reason - it's a rare beast to see the sort of charts we're seeing right now. It would appear the UK and much of Europe is headed into the freezer, but how cold, and for how long?
      As always, please keep to just discussing the model output in this thread.
      We have a thread open to discuss the cold spell - so if you're wanting to chat more generally about it, or talk about forecasts from the BBC, Met Office, Netweather etc, please head over there:
      https://www.netweather.tv/forum/topic/89358-ssw-related-cold-spell-will-it-wont-it/
      It's also worth keeping an eye on is the blogs from our team including @Jo Farrow & @Nick Finnis, there's some great info about the SSW, the cold spell etc, and new articles will be posted regularly:

      The much talked about SSW has taken place, but as Nick blogged about a few days ago, it doesn't always mean cold for the UK. The signs are good though (if you like cold that is), and the model output is showing a lot of northern blocking currently. It's set to be a really interesting time to follow the models if nothing else, so please carry on the discussion here. 
      As ever, please keep it to model discussion only in this thread.....

      Please only post about the model output in this thread - if you're unsure what this entails, and what thread you should be using, please see our posting guide:
      https://www.netweather.tv/forum/topic/89198-model-threads-posting-guide/.
      We don't want to do it, but we have and will either block from posting, or pre-moderate the posts of those who continually post off topic posts in here. So please don't let that be you, with what may be a very interesting/exciting spell of weather on the way.  
      If you spot a post which you believe may be off topic or breaking the forum guidelines in any way, please hit the report button, and don't respond in the thread. The team will deal with reports as quickly as they can.
