Planning Outlook
The unsettled period of weather will persist over the coming week with low pressure area centres tracking just to the northwest of Scotland, allowing south-westerly winds to prevail. Rainfall often showery in nature, but coming in frequently to western mountains with the greatest falls for western Scotland. Chilly and windy at times; freezing level touching highest tops Scotland on Tuesday and Wednesday, when showers may fall as wet snow at times over the tops. Temperatures trending warmer again next weekend, as pressure is likely to rise from the south to give drier weather more widely.
