Planning Outlook
A hint of a change as pressure builds across Britain from the coming weekend as the present stormy weather gradually subsides. On Friday and into the weekend, a final front could well become almost stationary for a day or so before fizzling out - still uncertainty as to its position (thus its footprint of rain and low cloud) in the otherwise improving picture as it becomes fine with light wind on the hills and overnight frost in lowland and upland valleys.
