Planning Outlook

All mountain areas of Britain from Friday 9th October 2015

Pressure will build across England and Wales eventually becoming an extension to a large high centred away to the northeast early next week, giving mainly fair conditions for several days ahead, but low cloud and drizzle may affect Western Islands and far NW of the Mainland on Friday. Winds will strengthen from the south-east around Saturday and may reach near gale force over westernmost ranges for a while. A good deal of dry, bright weather next week but as high pressure transfer to west of Ireland rain, drizzle and low cloud may start to affect the north and west of Scotland.
