Planning Outlook
A hint of a change as pressure builds across Britain from the coming weekend. For this week though, although not as stormy, further bands of rain and strong wind, particularly affecting western mountains. Into the weekend, a final front could well become almost stationary for a day or so before fizzling out - as yet uncertainty as to its position (thus its rain and low cloud) in the otherwise improving picture as it becomes fine with light wind on the hills.
