Here is a summary of the NWP output for 12z on Monday.
Issued 0525z, 5th July 2007.

The middle part of next week will see a mobile flow over the UK, with a
ridge bringing a respite before more unsettled weather moves in from the
west.

Analysis and evolution to T+120 via GFS
http://expert.weatheronline.co.uk/pslv_frame.htm
Low pressure lies to the NE, with a weak ridge over the UK. Winds are
westerlies for most as a result. A low moves over Scotland overnight and
into tomorrow, leading to strong westerlies and WSW'lies. The westerlies
persist on Saturday as the low moves away to the NE. Sunday sees a ridge
over England and Wales, with westerlies elsewhere.
