High pressure will dominate the weather over the next week. Winds will be light. Rain, if any, will be rare, sunshine extensive - although were it forms cloud banks will drift on only slowly. Frequently the air very clear giving excellent or superb visibility. Although often warm by day (particularly into next week), snow melt will be slow. There is just the risk of a front bringing temporarily stronger winds and low cloud to NW Scotland into Tuesday, but otherwise it may well be toward next weekend before the weather breaks.
