Planning Outlook
The present extensively dry and often relatively windless weather will end over the next few days as low pressure envelopes Britain. Showery conditions (snow on higher areas) will arrive on western mountains (mainly W & NW Scotland) on Saturday, before the threat of widespread rain - or snow higher areas of the Highlands - on Sunday. There may also be upland gales (although as yet considerable uncertainty for Sunday). Next week, frequent precipitation, low cloud and bouts of upland gales.
