Well GFS 06Z run has 850 hPa of -7C over London on Saturday. I find it
hard to believe that that would mean a max. of 6C? Clearly GFS has not
been followed, which is fair enough, but it shows the possibilities,
writing this one off 5 days away is far too premature in my view.

Maybe I'm never particularly overwhelmed by cold northerly-northwesterlies.
Although in fairness - maxima of 3c in London for Thursday, so clearly not
going with that view in the weekly forecast.

GFS has a much stronger Greenland high than EC/UKMO and if this the key
determinant then goodness knows what is going to happen !
