Planning Outlook

All mountain areas of Britain from Saturday 28th February 2015

Little change in the weather pattern unit the middle of next week: frequent upland gales and considerable precipitation focussed western mountains, particularly the W & NW Highlands. Rain frequently only lower slopes, although mainly from southern Scotland southwards, one or two brief periods of thaw up to higher slopes. Later next week, as pressure rises, much drier. Indeed, pressure will remain high close to Britain for perhaps a week or more. At present there is least certainty of dry conditions over NW Scotland where renewed bouts of upland gales and precipitation may develop.
