    I'm waiting for the MetOffice YouTube channel's Deep Dive; it will be fascinating this week. 

    Agreed - when might we expect to see it?

    The form horse here is for the system to head south of early modelling with France experiencing more of an “event” than southern UK. 

  2. I think it’s a little early to be cancelling plans for Thursday. There is clearly still a range of outcomes in terms of the track and intensity of the system, and forecast confidence will rise in the usual way as time progresses. The yellow warning is there now to raise awareness, so yes it’s time to contemplate/advise that some flexibility might be needed. But not yet to make definitive decisions as to what you will and won’t be doing on Thursday.

    A low-probability yellow warning ⚠️  for rain in the SE issued for this weekend. 

    My sense - and it is no more than that - is that the MetO are getting too trigger happy with weather warnings. The forecast(s) I’m looking at look seasonal, nothing more.

    If warnings are so frequent and for weather that is neither particularly threatening or unseasonal - then they will lose their impact. The same is true of “storm” naming. Not every system is a storm. We’ve seen the impact of sensationalism in mainstream journalism and politics; it will be a shame if the same happens in meteorology.

    There's a yellow warning ⚠️ for tonight's rain in the SE: 

    WWW.METOFFICE.GOV.UK

    Met Office UK weather warnings for rain, snow, wind, fog and ice. Choose your location to keep up to date with local weather warnings.

     

    This yellow warning has just been updated - essentially to cover a larger area westward. However the MetO forecast for my location (S of Woking, well within the area shown) has hardly any rainfall at all. I’ve not seen that before, usually the forecasts and warnings seem well sync’ed. We’ll see which is right!

    Odd transient ridge aside it all looks Atlantic driven as far as the eye can see..

    I'm happy to suffer this if we get something settled and colder in November..

    Is there a known linkage or pattern sequence - in fact anything beyond mean reversion - between an Atlantic driven October and a more settled cold November..?

    Hmm. BBC news article saying a “metre of rain” has fallen. But the article detail then quoting amounts of 100mm (ish).

    so either the UK 24 rainfall record has been shattered by a factor of 3, or somebody there needs some basic maths lessons! 🤔

    An excellent education on display here 🤦‍♂️

    It doesn't really matter though, its basically all one set of impacts. It makes more sense to call it one thing - the technicalities are less important than the consequences.

    It’s always difficult to get the scientists to accept that. For them the technicalities are everything!

  8. Not sure I understand your key.

    What is “SVR - Black outline” and why does it have a white outline?

    What does your forecast say for the area bounded by Oxford-London-Brighton-Southampton? Is that SVR because it is within the black outline covering Southern UK? Or Low because it is a light grey shaded area?

    Perhaps it’s just me. Sorry if so…

    The dp’s are generally fairly borderline where the main precip occurs so I wouldn’t be certain that we won’t see more of a slush fest than a winter wonderland away from >400 feet.

    its very tricky  

    Very very tricky…

    It goes without saying that higher is better, but it’s easy to see how this could result in quite a widespread fall also. MetO is right to put the warnings out. Dew points will be the key and they can generate and sustain their own change in precipitation. And the heaviest snow falls we see in this country tend to happen when temps are above freezing….
