Temperatures will vary during next week - highest Scottish summits will temporarily dip close to freezing point, but it will be often mild as southwesterlies prevail. Periods of gales or severe gales on the mountains. Frequent rain, some sustained heavy falls focused on western Scotland where flooding is possible through midweek. Less wet further south and east.
