My last reiteration on this as I accept that no amount of rationale is going to be worthwhile when disillusion with the weather in the UK overrides any reasoning behind it.
Personally I do find the 500mb charts broadly there for two weeks out with detail following within that framework far more often than not. an elephant fart in Thailand could introduce the butterfly effect that along with random chaos of the atmospheres scuppers any teleconnections theory beyond around 3 weeks in my humble opinion. In my view you can have as many global teleconnections theories as you like (they tend to come in fads until proven wrong ) but the simple fact of the matter is the chaos and butterfly effect that increasingly extrapolates its own merry dance the further out we look.
