Can't find any weather maps with fronts on (the weather.org.uk

is particularly disappointing for what should be the sunniest time of
year... can anyone confirm this?

How do you know? I don't think anyone can confirm it until it happens
Nick! At the moment everything is a forecast and the forecast charts
will always change somewhat before the events anyway. Judge it on
outcome and enjoy the sunny weather if it happens, or curse the
forecasters if it doesn't (that's what normally happens anyway!).

I've been on leave for more than a week now and have a policy of not
checking forecasts when not at work so this is not a comment on the
forecast for the coming week or how accurate any one source was (as I
do not know). However in general subsided marine boundary layers (esp.
Pm ones) tend to be rather cloudy with a lot of trapped Sc. How that
reacts on traversing land depends on a number of factors, maturity of
the layer, height of the inversion and BL flow strength are just
three. Sc forecasting is a nightmare at any time of the year and has a
huge impact on the weather and feel of the day.
To make things more difficult NWP models tend to under do boundary
layer cloud amounts, GFS being one of the worst offenders, as
evidenced by its tendency to overdo diurnal range. My experience, as a
user, is that GFS has fallen off the pace somewhat during the last 12
to 18 months, this supported by the statistics (depending on source)
placing it in roughly 3rd place with JMA, whilst GM and EC occupy the
top two positions. Certainly, as stated above, that fits with my
experience as a user of the various models.
