Planning Outlook for all mountain areas from Wednesday, 12th March, 2014
Fine, very warm for March and widely sunny mid-week. However, the NW Highlands will become cloudy with a little rain, and across the Highlands by Friday there will be rain and low cloud, mainly in the west. Pressure will fall slowly over the weekend as the high centre moves away south; but still substantially dry, although intermittent upland gales across Highland Scotland. Snowmelt, mostly during daylight, will continue until the weekend. This may cease on higher Scottish areas on Sunday.
