Planning Outlook
Mostly cloudy with precipitation from time to time over the next few days - although total rainfall is now expected to be fairly small on most mountains, particularly N Scotland. Temperature wise, it is highly likely to remain colder than recent January's with the snow pack across the Scottish Highlands being enhanced by further snowfall, whilst further south snow accumulates on higher areas, and occasional falls reaching lower slopes.
