But the 'Return of the Westerlies' and a 'zonal type' set up occurs in most
years around this time. Lamb detailed it and it is something I have noticed
that seems to happen in around 7 out of 10 years. Of course, the 'detail'
can make all the difference such as if the Jet Stream is just a little bit
to the north or to the south we can have a great detail of difference in
what weather we get, and if the Jet Stream is weaker or stronger, meanders
or not. Anyway, I am rambling on now and I am sure there are far more people
on this newsgroup better qualified than me to answer this question.

Turned very hazy now but the sun is still managing to shine through it.

No, no. Far from rambling! The re-establishment of a zonal type around
this time is well documented. I'm not sure about its statistical
reliability, but it is often referred to as the "European Monsoon". It
could be a result of strong heating over the continent/EAstern Europe,
drawing in Atlantic air after a spring hiatus.
