Planning Outlook
High pressure will continue to be the main influence into next week, particularly W & NW Highlands where extensively dry and wind often light. However, disappointing for other areas as 'gloomy' conditions predominate" patches of light rain and extensive low cloud and fog. Into next week, an area of low pressure will bring rain and wind in from the southwest but northern Scotland may escape most or all the rain.
