Planning Outlook

All mountain areas of Britain from Tuesday 25th October 2016

Benign conditions on Tuesday, but a transition to a west or southwesterly pattern will have taken place by Wednesday, as high pressure becomes centred across southern Britain. For the rest of the week, winds will be often strong, mainly Scottish mountains, at times gale force. Rain from time to time most western regions, plus extensive low cloud, but toward east & south, very little rain and higher cloud breaks. Becoming much milder than recently, or very warm for a few days, but a risk of turning colder by the start of next week.
